Is Card Hedge API live?

Yes — it answered the hub's last check (checked 3h ago). It answered 100% of checks over the last 30 days.

Is Card Hedge API free to use?

Not anonymously — it asks for a key or a login before it will serve. Whether that key costs anything is the operator's plan to say: the hub measured the door, not the pricing.

What tools does Card Hedge API have?

18 tools: search_cards, search_sets, search_cards_sorted, get_details_by_certs, get_all_prices, get_total_sales_by_player, get_player_index, search_players, ….

Is Card Hedge API safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  Get Card Details by Certificate Numbers (Batch) Get card details for multiple certificate numbers in a single request. This endpoint performs batch lookups without price history: 1. Checks the persistent validated-certificate cache for each certificate; queries GemRate only for certificates not successfully retrieved before 2. Fetches card details from CardHedge using GemRate IDs 3. Fallback: if step 2 finds no card, matches the GemRate description against the AI `card-match` endpoint 4. Returns certificate info and card details (or null if not found in either lookup) `card_source` reports how each card was resolved -- `gemrate_id` for the direct GemRate ID lookup, or `card_match` for the description fallback. When the fallback is used, `match_confidence` carries the AI match score (0-1); treat low-confidence matches with care. **Example curl:** ```bash curl -X POST -H "X-API-Key: your-api-key-here" \ -H "Content-Type: application/json" \ -d '{ "certs": ["76676185", "50000000", "12345678"], "grader": "PSA" }' \ "{base_url}/v1/cards/details-by-certs" ``` Returns card details for each certificate. Cards not found in CardHedge will have null card field. Maximum 100 certificates per request. Each submitted certificate counts as one unit toward the customer's minute and day rate limits, including duplicate and cached certificates. A batch that exceeds the remaining allowance is rejected with HTTP 429 before any certificates are processed. GemRate HTTP 400 not-found results are cached by grader and certificate and reused on later requests. Each account also has a daily budget of **uncached** certificate lookups (shared by every certificate endpoint and every API key of the account, resetting at 00:00 UTC). Only certificates that were never looked up before spend it. Once it is spent, cached certificates are still served and any other certificate comes back with `error: "gemrate_daily_quota_exceeded"`; if none of the batch could be served the request returns HTTP 429 with a `Retry-After` header. ### Responses: **200**: Successful Response (Success Response) Content-Type: application/json **Example Response:** ```json { "results": [ { "cert_info": { "grader": "psa", "cert": "76676185", "grade": "PSA 9", "gemrate_id": "9f4cd2db01a0a873ba5da0feb23428686fd556ac", "universal_gemrate_id": "9f4cd2db01a0a873ba5da0feb23428686fd556ac", "description": "2000 Pokemon Japanese Neo Wooper 194" } }, { "cert_info": { "grader": "psa", "cert": "50000000", "grade": "PSA 10", "gemrate_id": "25783324b9710f1366ca4d54f3dd4689c02b6885", "universal_gemrate_id": "25783324b9710f1366ca4d54f3dd4689c02b6885", "description": "1999 Bowman Chrome C.C.

  Get Latest Prices Across All Grades Get all latest prices for a card across all available grades. Requires a card_id. If you only have a card name/description, call `card-match` or `card-search` first to get the card_id, then use it here. This endpoint returns the most recent price for each grade/grader combination available for the specified card. Includes prices from all major grading companies (PSA, BGS, SGC, CGC, CSG, HGA) plus raw (ungraded) prices. The response includes: - Grade and grader information - Latest price for each grade - Display order for sorting grades consistently **Example curl:** ```bash curl -X POST -H "X-API-Key: your-api-key-here" \ -H "Content-Type: application/json" \ -d '{ "card_id": "1586414093385x612765462196125700" }' \ "{base_url}/v1/cards/all-prices-by-card" ``` Returns all available grades with their latest prices for the card. ### Responses: **200**: Successful Response (Success Response) Content-Type: application/json **Example Response:** ```json { "prices": [ { "card_id": "1586414093385x612765462196125700", "grade": "Raw", "grader": "Raw", "price": "1299.99", "display_order": "-1" }, { "card_id": "1586414093385x612765462196125700", "grade": "PSA 10", "grader": "PSA", "price": "16999.99", "display_order": "1" }, { "card_id": "1586414093385x612765462196125700", "grade": "PSA 9", "grader": "PSA", "price": "3700.00", "display_order": "2" }, { "card_id": "1586414093385x612765462196125700", "grade": "BGS 9.5", "grader": "BGS", "price": "5200.00", "display_order": "323" } ] } ``` **Output Schema:** ```json { "properties": { "prices": { "items": { "properties": { "card_id": { "type": "string", "title": "Card Id", "description": "Unique card identifier" }, "grade": { "type": "string", "title": "Grade", "description": "Card grade (e.g., PSA 10, BGS 9.5, Raw)" }, "grader": { "type": "string", "title": "Grader", "description": "Grading company (e.g., PSA, BGS, SGC, CGC)" }, "price": { "type": "string", "title": "Price", "description": "Latest price for this grade" }, "display_order": { "type": "string", "title": "Display Order", "description": "Display order for sorting grades" } }, "type": "object", "required": [ "card_id", "grade", "grader", "price", "display_order" ], "title": "GradePrice", "description": "Price information for a specific grade." }, "type": "array", "title": "Prices", "description": "Latest prices across all available grades" } }, "type": "object", "required": [ "prices" ], "title": "AllPricesByCardResponse", "description": "Response model for all latest prices by card endpoint.", "examples": [ { "prices": [ { "card_id": "1586414093385x612765462196125700", "display_order": "-1", "grade": "Raw", "grader": "Raw", "price": "1299.99" }, { "card_id": "1586414093385x612765462196125700", "display_order": "1", "grade": "PSA 10", "grader": "PSA", "price": "16999.99" }, { "card_id": "1586414093385x612765462196125700", "display_order": "2", "grade": "PSA 9", "grader": "PSA", "price": "3700.00" }, { "card_id": "1586414093385x612765462196125700", "display_order": "323", "grade": "BGS 9.5", "grader": "BGS", "price": "5200.00" } ] } ] } ```

  Get Total Sales Count by Player Get total sales counts per player/character over a recent window. Counts sales records from the last N days that mention each player or character name. Returns only the counts — no individual sale records — so it stays fast even for high-volume players. **Parameters:** - `players`: List of player/character names (max 25) - `days`: Look-back window in days (default: 30, max: 365) ### Responses: **200**: Successful Response (Success Response) Content-Type: application/json **Example Response:** ```json { "results": [ { "player": "Mike Trout", "total_sales": 12809, "search_time_ms": 391 }, { "player": "Shohei Ohtani", "total_sales": 87192, "search_time_ms": 618 } ], "days": 30 } ``` **Output Schema:** ```json { "properties": { "results": { "items": { "properties": { "player": { "type": "string", "title": "Player", "description": "Player/character name searched" }, "total_sales": { "type": "integer", "title": "Total Sales", "description": "Total number of sales found" }, "search_time_ms": { "type": "integer", "title": "Search Time Ms", "description": "Upstream search request time in ms" } }, "type": "object", "required": [ "player", "total_sales", "search_time_ms" ], "title": "PlayerSalesResult" }, "type": "array", "title": "Results" }, "days": { "type": "integer", "title": "Days", "description": "Number of days looked back" } }, "type": "object", "required": [ "results", "days" ], "title": "TotalSalesByPlayerResponse" } ```

• get_player_index reads auth-required never probed

  Get Player Index Latest cached player index: a market-cap-weighted average price (USD) of the player's top-10 cards, with 1d/7d/30d/90d/365d changes and the cards behind it. Identify the player by `player_id` (recommended — from `player-search`) or by `name` (+ optional `category`). A name must match exactly one player, otherwise the response is 409 with `candidates`. Merged duplicate IDs resolve to their canonical player (`resolution.resolved_via: "alias"`). `status` is `current` (updated within `PLAYER_INDEX_STALE_DAYS` days, default 2), `stale` (older; still served — the API never triggers a recalculation), or `withheld` (at least `PLAYER_INDEX_WITHHOLD_FOREIGN_PCT` percent, default 25, of the index's weight comes from other players' cards; `value` is null and `integrity.reason` explains). **Example curl:** ```bash curl -X POST -H "X-API-Key: your-api-key-here" -H "Content-Type: application/json" -d '{"name":"Luka Doncic"}' "{base_url}/v1/cards/player-index" ``` ### Responses: **200**: Successful Response (Success Response) Content-Type: application/json **Example Response:** ```json { "player": { "player_id": "1585918730738x583198232556601300", "name": "Luka Doncic", "categories": [ "Basketball" ], "aliases": [] }, "resolution": { "requested_player_id": "1585918730738x583198232556601300", "resolved_via": "player_id" }, "index": { "value": 948.01, "as_of": "2026-09-25", "status": "current", "days_since_update": 0, "volume_30d": 357, "card_count": 10, "changes": { "1d": { "abs": 11.52, "pct": 1.23 }, "7d": { "abs": -20.4, "pct": -2.11 } }, "methodology": { "algorithm": "market_cap_weighted", "base_grade": "PSA 10", "version": "2.0.0" } }, "integrity": { "verdict": "ok", "foreign_weight_pct": 0.0, "unknown_weight_pct": 0.0 }, "constituents": [ { "card_id": "1588995508450x437304889574424600", "card_name": "Luka Doncic 2018 Panini Prizm Basketball Silver", "set": "2018 Panini Prizm Basketball", "variant": "Silver", "grade": "PSA 10", "price": 1850.0, "weight": 40.0, "volume_30d": 38, "owned_by_player": true } ] } ``` **Output Schema:** ```json { "properties": { "player": { "properties": { "player_id": { "type": "string", "title": "Player Id", "description": "Canonical Card Hedge player ID" }, "name": { "type": "string", "title": "Name" }, "categories": { "items": { "type": "string" }, "type": "array", "title": "Categories" }, "aliases": { "items": { "type": "string" }, "type": "array", "title": "Aliases", "description": "Player IDs merged into this player" } }, "type": "object", "required": [ "player_id", "name" ], "title": "PlayerBlock" }, "resolution": { "properties": { "requested_player_id": { "title": "Requested Player Id" }, "requested_name": { "title": "Requested Name" }, "requested_category": { "title": "Requested Category" }, "resolved_via": { "type": "string", "enum": [ "player_id", "alias", "name" ], "title": "Resolved Via" } }, "type": "object", "required": [ "resolved_via" ], "title": "ResolutionBlock" }, "index": { "properties": { "value": { "title": "Value", "description": "USD: market-cap-weighted average price of the top-10 cards;

• search_players reads auth-required never probed

  Search Players Search Card Hedge's canonical player catalog by partial name. Duplicate player records (e.g. two "LeBron James" records) are folded into one canonical player: `player_id` is the canonical ID and `aliases` lists the merged IDs, whose stats are summed. `categories` lists every category the player appears in; the optional `category` filter matches any of them. `index` says whether a player index is available (`current`, `stale`, `withheld`, or `none`). Results are ranked by 30-day sales and capped by `count`. **Example curl:** ```bash curl -X POST -H "X-API-Key: your-api-key-here" -H "Content-Type: application/json" -d '{"search":"Luka","count":5}' "{base_url}/v1/cards/player-search" ``` ### Responses: **200**: Successful Response (Success Response) Content-Type: application/json **Example Response:** ```json { "count": 1, "players": [ { "player_id": "1585495598505x695909526016884700", "name": "Michael Jordan", "categories": [ "Basketball", "Baseball" ], "aliases": [], "cards_tracked": 3746, "thirty_day_sales": 20946, "index": { "has_index": true, "as_of": "2026-09-25", "status": "current" } } ] } ``` **Output Schema:** ```json { "properties": { "count": { "type": "integer", "minimum": 0.0, "title": "Count", "description": "Number of players returned" }, "players": { "items": { "properties": { "player_id": { "type": "string", "minLength": 1, "title": "Player Id", "description": "Canonical Card Hedge player ID.

• get_fmv_by_cert reads auth-required never probed

  Get Fair Market Value (FMV) by Certificate Number Get the Fair Market Value (FMV) for a card by grader certificate number. Convenience wrapper that chains a certificate lookup into an FMV valuation, so callers holding only a cert number do not need to resolve the card themselves. ## How it works 1. Checks the persistent validated-certificate cache; queries GemRate only when that certificate has not been successfully retrieved before. 2. Resolves the card in CardHedge using the GemRate IDs. 3. Fallback: if step 2 finds no card, matches the GemRate description against the AI `card-match` endpoint. 4. Requests the FMV for the resolved card at the certificate's grade. ## Card resolution (`card_source` / `match_confidence`) - `card_source: "gemrate_id"` — direct GemRate ID → CardHedge lookup succeeded. `match_confidence` is null. - `card_source: "card_match"` — direct lookup found nothing; the card was matched from the GemRate description via the AI fallback. `match_confidence` (0-1) is the matcher's score; **treat an FMV derived from a low-confidence match with care**. Cards resolved this way have null `category_group` and `set_type` because the matcher doesn't return those two fields. ## FMV (`fmv`) The `fmv` object is identical to the `/v1/cards/card-fmv` response — see that endpoint for the full method cascade (`direct`, `card_interpolation`, `cross_provider`, `anchor_multiplier`, `segment_fallback`, `no_data`), `_indexed` variants, confidence grading, and movement-index metadata. ## When fields are null - `card` and `fmv` are both null only when the certificate cannot be matched to a card by EITHER the GemRate ID lookup or the description fallback. - When the card is found but the upstream has insufficient sale data, `fmv` is a populated object with `method: "no_data"` and `price: null` — `card` is still populated in this case. **Example curl:** ```bash curl -X POST -H "X-API-Key: your-api-key-here" \ -H "Content-Type: application/json" \ -d '{ "cert": "50000000", "grader": "PSA" }' \ "{base_url}/v1/cards/fmv-by-cert" ``` ### Responses: **200**: Successful Response (Success Response) Content-Type: application/json **Example Response:** ```json { "cert_info": { "grader": "psa", "cert": "50000000", "grade": "PSA 10", "gemrate_id": "25783324b9710f1366ca4d54f3dd4689c02b6885", "universal_gemrate_id": "25783324b9710f1366ca4d54f3dd4689c02b6885", "description": "1999 Bowman Chrome C.C.

  Get Price History by Certificate Number Get card information and pricing by grader certificate number. This endpoint performs a multi-step lookup: 1. Checks the persistent validated-certificate cache; queries GemRate only when that certificate has not been successfully retrieved before 2. Fetches card details from CardHedge using GemRate IDs 3. Fallback: if step 2 finds no card, matches the GemRate description against the AI `card-match` endpoint 4. Retrieves price history for the card at the specified grade, served from the synced `card_prices` table with upstream fallback for cards the sync does not cover **Related:** to look up many certificates at once, use `details-by-certs` (card details only) or `batch-prices-by-cert` (one price estimate per cert instead of price history). `card_source` reports how the card was resolved -- `gemrate_id` for the direct GemRate ID lookup, or `card_match` for the description fallback. When the fallback is used, `match_confidence` carries the AI match score (0-1); treat prices derived from a low-confidence match with care. Cards resolved via the `card_match` fallback have null `category_group` and `set_type` -- the matcher does not return those two fields. **Example curl:** ```bash # Default: 180 days of price history curl -X POST -H "X-API-Key: your-api-key-here" \ -H "Content-Type: application/json" \ -d '{ "cert": "76676185", "grader": "PSA" }' \ "{base_url}/v1/cards/prices-by-cert" # Custom: 30 days of price history curl -X POST -H "X-API-Key: your-api-key-here" \ -H "Content-Type: application/json" \ -d '{ "cert": "76676185", "grader": "PSA", "days": 30 }' \ "{base_url}/v1/cards/prices-by-cert" ``` Returns certificate info, card details, and price history (default: 180 days, max: 365 days). ### Responses: **200**: Successful Response (Success Response) Content-Type: application/json **Example Response:** ```json { "cert_info": { "grader": "psa", "cert": "50000000", "grade": "PSA 10", "gemrate_id": "25783324b9710f1366ca4d54f3dd4689c02b6885", "universal_gemrate_id": "25783324b9710f1366ca4d54f3dd4689c02b6885", "description": "1999 Bowman Chrome C.C.

  Get Price History for a Card Get price history for a specific card and grade. Requires a card_id. If you only have a card name/description, call `card-match` or `card-search` first to get the card_id, then use it here. Returns daily price points for the card at the requested grade. By default the window ends today, so `days` alone reaches back at most one year (366 days). Results are cached for improved performance. ## Getting price history older than one year Set `end_date` to shift the `days` window into the past and page backwards, one window at a time. Each response covers `(end_date - days, end_date]` — exclusive start, inclusive end — so consecutive pages are contiguous and never overlap or skip a day. **Paging by calendar year:** | Page | Request body | |------|--------------| | This year to date | `{"card_id": "...", "grade": "PSA 9", "days": <days since Dec 31>}` | | 2025 | `{"card_id": "...", "grade": "PSA 9", "days": 365, "end_date": "2025-12-31"}` | | 2024 (leap year) | `{"card_id": "...", "grade": "PSA 9", "days": 366, "end_date": "2024-12-31"}` | | 2023 | `{"card_id": "...", "grade": "PSA 9", "days": 365, "end_date": "2023-12-31"}` | | ... | continue stepping `end_date` back a year at a time | Stop paging when a response returns an empty `prices` list — you have reached the start of the card's history (price coverage generally begins around spring 2020). Use `days: 366` for leap years so the page covers the full calendar year; `end_date` may not be in the future. Windows that end in the past are immutable, so they are cached longer (24 hours) than live windows (1 hour) — historical pages are fast and cheap to re-request. **Example curl:** ```bash # Default: 180 days of price history curl -X POST -H "X-API-Key: your-api-key-here" \ -H "Content-Type: application/json" \ -d '{ "card_id": "1587446850514x224832321163624450", "grade": "PSA 9" }' \ "{base_url}/v1/cards/prices-by-card" # Custom: 30 days of price history curl -X POST -H "X-API-Key: your-api-key-here" \ -H "Content-Type: application/json" \ -d '{ "card_id": "1587446850514x224832321163624450", "grade": "PSA 9", "days": 30 }' \ "{base_url}/v1/cards/prices-by-card" # Historical: calendar year 2024 (366 days, leap year) curl -X POST -H "X-API-Key: your-api-key-here" \ -H "Content-Type: application/json" \ -d '{ "card_id": "1587446850514x224832321163624450", "grade": "PSA 9", "days": 366, "end_date": "2024-12-31" }' \ "{base_url}/v1/cards/prices-by-card" ``` Returns price history (default window: 180 days; max: 366 days per window). ### Responses: **200**: Successful Response (Success Response) Content-Type: application/json **Example Response:** ```json { "prices": [ { "closing_date": "2025-10-26T23:59:00.000Z", "Grade": "PSA 9", "card_id": "1587446850514x224832321163624450", "price": "337.67" }, { "closing_date": "2025-10-25T23:59:00.000Z", "Grade": "PSA 9", "card_id": "1587446850514x224832321163624450", "price": "337.00" }, { "closing_date": "2025-10-24T23:59:00.000Z", "Grade": "PSA 9", "card_id": "1587446850514x224832321163624450", "price": "331.29" } ] } ``` **Output Schema:** ```json { "properties": { "prices": { "items": { "properties": { "closing_date": { "type": "string", "title": "Closing Date", "description": "Date of the price point" }, "Grade": { "type": "string", "title": "Grade", "description": "Card grade" }, "card_id": { "type": "string", "title": "Card Id", "description": "Card ID" }, "price": { "type": "string", "title": "Price", "description": "Price value" } }, "type": "object", "required": [ "closing_date", "Grade", "card_id", "price" ], "title": "PriceHistory", "description": "Individual price point from CardHedge." }, "type": "array", "title": "Prices", "description": "Daily price history for the specified card and grade" } }, "type": "object", "required": [ "prices" ], "title": "PricesByCardResponse", "description": "Response model for prices by card endpoint.", "examples": [ { "prices": [ { "Grade": "PSA 9", "card_id": "1587446850514x224832321163624450", "closing_date": "2025-10-26T23:59:00.000Z", "price": "337.67" }, { "Grade": "PSA 9", "card_id": "1587446850514x224832321163624450", "closing_date": "2025-10-25T23:59:00.000Z", "price": "337.00" }, { "Grade": "PSA 9", "card_id": "1587446850514x224832321163624450", "closing_date": "2025-10-24T23:59:00.000Z", "price": "331.29" } ] } ] } ```

  Get Comparable Sales (Comps) Get comparable sales (comps) for a card, with anomaly filtering and optional time-weighting. Requires a card_id. If you only have a card name/description, call `card-match` or `card-search` first to get the card_id, then use it here. This endpoint: 1. Fetches the most recent sales for the card at the requested grade 2. Filters only statistical price anomalies using IQR fences (keeps non-anomalous highs/lows) 3. Calculates comp price using either: - Simple average (default) - Weighted Moving Average (if time_weighted=True), giving recent sales more weight 4. Returns `high`/`low` from the filtered sales used in the comp 5. Returns `raw_high`/`raw_low` from the unfiltered sales fetched for the request 6. Optionally returns raw price data (if include_raw_prices=True) **Time-Weighting Algorithm (WMA):** When time_weighted=True, recent sales are weighted more heavily: - Most recent sale: weight = n - Second most recent: weight = n-1 - ... - Oldest sale: weight = 1 - Formula: (P1*n + P2*(n-1) + ... + Pn*1) / (n + (n-1) + ... + 1) **Example curl:** ```bash # Basic comp (simple average) curl -X POST -H "X-API-Key: your-api-key-here" \ -H "Content-Type: application/json" \ -d '{ "card_id": "1587446850514x224832321163624450", "count": 10, "grade": "PSA 9" }' \ "{base_url}/v1/cards/comps" # Time-weighted comp with raw prices curl -X POST -H "X-API-Key: your-api-key-here" \ -H "Content-Type: application/json" \ -d '{ "card_id": "1587446850514x224832321163624450", "count": 10, "grade": "PSA 10", "time_weighted": true, "include_raw_prices": true }' \ "{base_url}/v1/cards/comps" ``` Returns calculated comp price with anomaly-aware filtering. ### Responses: **200**: Successful Response (Success Response) Content-Type: application/json **Example Response:** ```json { "comp_price": 336.0, "high": 348.0, "low": 325.0, "raw_high": 348.0, "raw_low": 325.0, "count_requested": 5, "count_used": 5, "time_weighted": true, "raw_prices": [ { "price": 325.0, "sale_date": "2025-10-26T13:00:00.000Z", "price_source": "marketplace", "card_id": "1587446850514x224832321163624450", "price_history_id": "1761480061129x501444455762531900", "grade": "PSA 9", "sale_type": "Best Offer", "title": "[listing title]", "sale_url": "[sale url]", "image": "[image url]" }, { "price": 348.0, "sale_date": "2025-10-26T03:36:00.000Z", "price_source": "marketplace", "card_id": "1587446850514x224832321163624450", "price_history_id": "1761446206940x522975047258362750", "grade": "PSA 9", "sale_type": "Auction", "title": "[listing title]", "sale_url": "[sale url]", "image": "[image url]" } ] } ``` **Output Schema:** ```json { "properties": { "comp_price": { "type": "number", "title": "Comp Price", "description": "Calculated comparable price (after anomaly filtering)" }, "high": { "type": "number", "title": "High", "description": "Highest sale price used in comp calculation" }, "low": { "type": "number", "title": "Low", "description": "Lowest sale price used in comp calculation" }, "raw_high": { "type": "number", "title": "Raw High", "description": "Highest unfiltered sale price fetched for this comp request" }, "raw_low": { "type": "number", "title": "Raw Low", "description": "Lowest unfiltered sale price fetched for this comp request" }, "count_requested": { "type": "integer", "title": "Count Requested", "description": "Number of prices requested" }, "count_used": { "type": "integer", "title": "Count Used", "description": "Number of prices used in calculation (after anomaly filtering)" }, "time_weighted": { "type": "boolean", "title": "Time Weighted", "description": "Whether time-weighted algorithm was used" }, "raw_prices": { "title": "Raw Prices", "description": "Raw price data (only included if include_raw_prices=true)" } }, "type": "object", "required": [ "comp_price", "high", "low", "raw_high", "raw_low", "count_requested", "count_used", "time_weighted" ], "title": "CompsResponse", "description": "Response schema for comp prices.", "examples": [ { "comp_price": 336.0, "count_requested": 5, "count_used": 5, "high": 348.0, "low": 325.0, "raw_high": 348.0, "raw_low": 325.0, "raw_prices": [ { "card_id": "1587446850514x224832321163624450", "grade": "PSA 9", "image": "[image url]", "price": 325.0, "price_history_id": "1761480061129x501444455762531900", "price_source": "marketplace", "sale_date": "2025-10-26T13:00:00.000Z", "sale_type": "Best Offer", "sale_url": "[sale url]", "title": "[listing title]" }, { "card_id": "1587446850514x224832321163624450", "grade": "PSA 9", "image": "[image url]", "price": 348.0, "price_history_id": "1761446206940x522975047258362750", "price_source": "marketplace", "sale_date": "2025-10-26T03:36:00.000Z", "sale_type": "Auction", "sale_url": "[sale url]", "title": "[listing title]" } ], "time_weighted": true } ] } ```

  Get Price Estimate for a Card Get a price estimate for a card at a specific grade. Requires a card_id. If you only have a card name/description, call `card-match` or `card-search` first to get the card_id, then use it here. This endpoint uses CardHedge's correlated price estimation service to provide price estimates with confidence intervals. The estimation can use either direct sales data or correlated pricing from similar cards. **Response Fields:** - `price`: Estimated price in USD - `price_low`: Lower bound of price estimate - `price_high`: Upper bound of price estimate - `confidence`: Confidence score (0-1) - `method`: Estimation method used ('direct' or 'correlated') - `freshness_days`: Age of data used for estimation in days - `support_grades`: Number of supporting grade data points - `grade_label`: Grade label used for estimation - `provider`: Grading provider (e.g., 'PSA', 'BGS') - `grade_value`: Numeric grade value **Example curl:** ```bash curl -X POST -H "X-API-Key: your-api-key-here" \ -H "Content-Type: application/json" \ -d '{ "card_id": "1586812246197x228181943611293700", "grade": "PSA 9" }' \ "{base_url}/v1/cards/price-estimate" ``` Returns price estimate with confidence bounds and metadata. ### Responses: **200**: Successful Response (Success Response) Content-Type: application/json **Example Response:** ```json { "price": 349.99, "price_low": 329.2, "price_high": 370.78, "confidence": 0.3869, "method": "direct", "freshness_days": 0, "support_grades": 1, "grade_label": "PSA 9", "provider": "PSA", "grade_value": 9.0 } ``` **Output Schema:** ```json { "properties": { "price": { "title": "Price", "description": "Estimated price in USD (null when no data available)" }, "price_low": { "title": "Price Low", "description": "Lower bound of price estimate (null when no data available)" }, "price_high": { "title": "Price High", "description": "Upper bound of price estimate (null when no data available)" }, "confidence": { "type": "number", "title": "Confidence", "description": "Confidence score (0-1)" }, "method": { "type": "string", "title": "Method", "description": "Estimation method used (e.g., 'direct', 'correlated', 'segment_fallback')" }, "freshness_days": { "title": "Freshness Days", "description": "Age of data used for estimation in days (null for fallback methods)" }, "support_grades": { "type": "integer", "title": "Support Grades", "description": "Number of supporting grade data points" }, "grade_label": { "type": "string", "title": "Grade Label", "description": "Grade label used for estimation" }, "provider": { "type": "string", "title": "Provider", "description": "Grading provider (e.g., 'PSA', 'BGS', 'AGS')" }, "grade_value": { "type": "number", "title": "Grade Value", "description": "Numeric grade value" } }, "type": "object", "required": [ "confidence", "method", "support_grades", "grade_label", "provider", "grade_value" ], "title": "PriceEstimateResponse", "description": "Response model for price estimation endpoint.", "examples": [ { "confidence": 0.3809, "freshness_days": 2, "grade_label": "PSA 9", "grade_value": 9.0, "method": "direct", "price": 385.0, "price_high": 407.92, "price_low": 362.08, "provider": "PSA", "support_grades": 1 } ] } ```

• match_card reads auth-required never probed

  Match a Card from a Text Description (AI) Match a natural language card description to the best card in the CardHedge database. Uses AI to evaluate search results and return the single best match with a confidence score. **How it works:** 1. Your query is sent to the card search API to find candidates 2. An LLM evaluates each candidate against your description 3. The best match is returned with a confidence score (0.0 - 1.0) **Confidence levels:** - **0.9 - 1.0**: Very high confidence — near-exact match - **0.7 - 0.9**: High confidence — likely correct match - **0.5 - 0.7**: Moderate confidence — possible match, verify manually - **Below 0.5**: No match returned (threshold not met) **Example curl:** ```bash curl -X POST -H "X-API-Key: your-api-key-here" \ -H "Content-Type: application/json" \ -d '{ "query": "2025 Topps Chrome Cooper Flagg 251", "category": "Basketball" }' \ "{base_url}/v1/cards/card-match" ``` ### Responses: **200**: Best matching card, or a null match below the confidence threshold (Success Response) Content-Type: application/json **Example Response:** ```json { "match": { "confidence": 0.95, "reasoning": "Exact match on player, year, set, and card number.", "description": "Shohei Ohtani 2018 Topps Chrome Baseball", "player": "Shohei Ohtani", "set": "2018 Topps Chrome Baseball", "number": "150", "variant": "Base", "card_id": "1587446850514x224832321163624450", "image": "https://images.example.com/ohtani-150.jpg", "category": "Baseball", "prices": [ { "grade": "PSA 10", "price": "850" }, { "grade": "PSA 9", "price": "125" } ] }, "candidates_evaluated": 10, "search_query_used": "2018 Topps Chrome Shohei Ohtani #150" } ``` **Output Schema:** ```json { "properties": { "match": { "description": "Best matching card with confidence score, or null if no confident match found" }, "candidates_evaluated": { "type": "integer", "title": "Candidates Evaluated", "description": "Number of candidate cards evaluated by the AI" }, "search_query_used": { "type": "string", "title": "Search Query Used", "description": "The search query that was sent to the card search API" } }, "type": "object", "required": [ "candidates_evaluated", "search_query_used" ], "title": "CardMatchResponse", "description": "Response model for AI-powered card matching.", "examples": [ { "candidates_evaluated": 10, "match": { "card_id": "1587446850514x224832321163624450", "category": "Baseball", "confidence": 0.95, "description": "Shohei Ohtani 2018 Topps Chrome Baseball", "image": "//s3.amazonaws.com/appforest_uf/example.jpg", "number": "150", "player": "Shohei Ohtani", "prices": [ { "grade": "PSA 10", "price": "850" }, { "grade": "PSA 9", "price": "125" } ], "reasoning": "Exact match on player (Shohei Ohtani), year (2018), set (Topps Chrome), and variant (Base).

  Get Fair Market Value (FMV) for a Card Get the Fair Market Value (FMV) for a card at a specific grade. Requires a `card_id`. If you only have a card name/description, call `match-card` or `card-search` first to resolve it. ## What FMV is FMV is CardHedge's smoothed valuation for a card at a specific grade, computed by an underlying pricing service that: 1. Looks for a direct price for this card+grade, and if found, replaces the raw `latest_price` with a **Winsorized-median FMV** computed over a 7/15/30/90-day window (the shortest window with enough daily prints wins). Winsorizing trims outlier sales so a single hot/cold day doesn't move the value. 2. If no direct price exists, falls back through a cascade of related data: other grades of the same card → other graders → grade multipliers → segment baselines. 3. If the chosen base price is stale, overlays a **movement index** to project it to today. The index is picked from the most specific level with enough sample density (card+grade → card → player → segment). 4. Returns the price, a confidence score, and full metadata so callers can decide how much to trust the result. Compared to `price-estimate`, the FMV response includes the smoothing window, sample counts, confidence grade, and a human-readable `price_explanation`. ## FMV calculation methods (the **method** field) The `method` field tells you which cascade step produced the price. There are **6 base methods** plus an `_indexed` variant of each non-terminal method (10 indexed + 1 terminal = 11 possible values). **Base methods**, in cascade priority: | Method | Meaning | | --------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | `direct` | Exact card+grade lookup. The 7/15/30/90-day Winsorized-median FMV is used when enough daily prints exist; otherwise raw `latest_price` is returned. See `fmv_window_days` / `fmv_sample_count`. | | `card_interpolation` | No direct price; isotonic regression in log-space across the card's OTHER same-provider grades, interpolated/extrapolated to the target grade. Requires 2+ supporting grades. | | `cross_provider` | No same-provider data; translates from another grader (e.g., BGS 9 → PSA 9) using a learned price ratio. | | `anchor_multiplier` | One same-provider grade is the anchor; a within-provider grade multiplier projects it to the target. Variants: same-provider, chained (e.g., BGS 8.5 → BGS 9 → PSA 9), raw (Raw → graded). | | `segment_fallback` | Last resort: uses the (set × year × category) segment baseline price and applies a grade multiplier. Lowest confidence — no card-specific data was used. | | `no_data` | Terminal: nothing in the cascade produced a usable price. `price` and the range bounds are null. | **`_indexed` variants** — `direct_indexed`, `card_interpolation_indexed`, `cross_provider_indexed`, `anchor_multiplier_indexed`, `segment_fallback_indexed`. The base method produced a stale price (older than the freshness threshold), so a **movement index** was overlaid to bring it to today. The index is chosen from a cascade of entities: - `index_level: "card_grade"` — most specific: this card at this grade - `index_level: "card"` — blended across all grades of this card - `index_level: "player"` — player-level (all this player's cards) - `index_level: "segment"` — (year × category) segment-level - `index_level: "none"` — stale, but no index met the minimum sample threshold (an `un_indexed_penalty` was applied to confidence) - `index_level: null` — fresh estimate, no adjustment was needed Examine `raw_price` (pre-adjustment) vs `price` (post-adjustment) and `index_pct_change` to see exactly what the index changed. Filter low-signal adjustments by requiring `index_sample_count >= 10`. ## Picking a method by use case - **Pricing UI for end users** — Trust `confidence_grade` A/B; show `price_explanation` on a "How was this calculated?" tooltip. Hide or caveat C/D and `no_data`. - **Portfolio valuation** — Use `price` directly; band it with `price_low` / `price_high` for uncertainty visualization. - **Sensitive financial decisions** — On C-grade or any `_indexed` method, also show `raw_price` so the user can see what the movement index changed. - **Bulk analytics** — Aggregate by `method` to see what % of cards have direct data vs are interpolated vs fall back to segments. ## Response field reference See the response schema (CardFMVResponse) for the full field-by-field description. Highlights: - `price` / `price_low` / `price_high` — FMV and uncertainty band in USD. - `confidence` (0-1) and bucketed `confidence_grade` (A/B/C/D) — single trust score folding in method, FMV quality, and index quality. - `raw_price` — pre-adjustment price. Differs from `price` when a movement index was applied (`_indexed`), or shows the FMV value for `direct` when latest_price was replaced. - `fmv_window_days` / `fmv_sample_count` — FMV smoothing window (7/15/30/90) and sample density. - `index_level` / `index_pct_change` / `index_sample_count` / `index_truncated` / `as_of_date` — movement-index provenance. - `cross_grade_fmv_count` — for cross-grade methods, how many source grades had their `latest_price` FMV-substituted before the cascade ran. - `price_explanation` — plain-English derivation (debug/audit only). Any additional fields the upstream returns are passed through unchanged. **Example curl:** ```bash curl -X POST -H "X-API-Key: your-api-key-here" \ -H "Content-Type: application/json" \ -d '{ "card_id": "1586812246197x228181943611293700", "grade": "PSA 9" }' \ "{base_url}/v1/cards/card-fmv" ``` ### Responses: **200**: Successful Response (Success Response) Content-Type: application/json **Example Response:** ```json { "price": 2000.0, "price_low": 1908.05, "price_high": 2091.95, "confidence": 0.9772, "method": "direct", "freshness_days": 3, "support_grades": 1, "grade_label": "BGS 9.5", "provider": "BGS", "grade_value": 9.5, "index_truncated": false, "confidence_grade": "A", "price_explanation": "Used latest_price $2000.00 (card_grade_prints direct lookup).
