api record

Demandex mines community demand for physical products. It classifies Reddit complaint and intent posts across 82 communities into demand signals (replacement-part hunts, unmet needs, willingness-to-pay, repeat failures), clusters them into scored opportunity cards with verbatim evidence and permalinks, and answers ad-hoc demand verdicts for any query. A free honest sample and a free category index let an agent learn the shapes before paying; paid tiers return trending teasers, category lists, full evidence cards, and demand verdicts (7-day cached or live research). Physical products only.…

Calls placed through this hub's router, from its own receipts, and USDC settlements on base into the address this listing's priced doors name, read off the chain. Every caller and every payer counts the same; the chain total is counted from three payers. The address also stands behind 5 other origins: the chain figures are the gateway's, not this listing's alone. How it is counted.

_ what it can do 6 tools
3 paid 3 never probed 3 of 6 classified

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.

  • trending reads 0.01 USDC paid never probed

    Paid ($0.01 USDC via x402). Returns the top 20 active opportunity cards by score as TEASERS — { id, slug, title, category, score, signalCount, lastSeen } only. No evidence and no productAngle (buy GET /v1/opportunity for the full card). While the index is still warming and no active cards exist yet, you get a no-charge 503 corpus_warming (never an empty charged list) — poll the free GET /v1/categories to see when cards go live. Compute-first / settle-after — you are not charged on any error. Response carries fetchedAt.

    demandextrending

  • brief reads 0.25 USDC paid never probed

    Whole-job market brief for agents. One payment returns current trending demand signals, the top 10 highest-scored open opportunities (optionally filtered by category), and per-category counts — equivalent to several separate paid calls. Pass ?category= to restrict the opportunities section to one category slug (an unknown slug returns a no-charge 400 listing the known categories). While the index is still warming and there are no trending signals and no open opportunities, you get a no-charge 503 corpus_warming instead of an empty charged brief. Compute-first / settle-after — you are not charged on any error. Response carries generatedAt plus per-section timestamps.

    demandexbrief

  • gauge reads 0.03 USDC paid never probed

    Paid ($0.03 USDC via x402). POST { "query": "...", "category"?: "..." } to get a demand verdict for any physical-product query. Answers are cached 7 days by normalized query; on a cache miss Demandex matches the query against the mined corpus (signals and cards by keyword) and runs one LLM synthesis call. query must be 3..200 chars. Reads the JSON body first, falling back to ?query=. Verdict shape: { query, verdictScore (0-100), demandTemperature (cold|warm|hot), rationale, topEvidence[] (≤5, each { quote, permalink, upvotes }), relatedOpportunities[] (≤5, each { slug, score }), cache (hit|miss), fetchedAt }. A zero-match query is a real cold verdict (chargeable), not an error. If the LLM is unavailable you get a 503 and are not charged. Compute-first / settle-after.

    demandexgauge

  • list reads unknown never probed

    Paid ($0.02 USDC via x402). Returns up to 50 active opportunity cards in a category, each as a teaser ({ id, slug, title, category, score, signalCount, lastSeen }) plus its summary. Requires ?category=; ?minScore= optionally filters. A missing or unknown category returns a no-charge 400 that lists the valid categories; a valid category with no active cards yet (index still warming) returns a no-charge 503 corpus_warming instead of an empty charged list. Compute-first / settle-after — you are not charged on any error. Response carries fetchedAt.

    demandexlist

  • card reads unknown never probed

    Paid ($0.05 USDC via x402). Returns one full opportunity card by ?id= or ?slug= (exactly one required, else a no-charge 400): all score components (freqScore, intensityScore, wtpScore), productAngle, summary, evidence[] (verbatim quotes with subreddit, upvotes, permalink), builderMomentum, firstSeen, lastSeen, signalCount, distinctAuthors. Compute-first / settle-after — you are not charged when the id/slug is missing, ambiguous, or not found. Response carries fetchedAt.

    demandexcard

  • gaugeLive reads unknown never probed

    Paid ($0.10 USDC via x402). Same body as /v1/gauge — POST { "query": "...", "category"?: "..." } (query 3..200 chars; body-first, ?query= fallback). Combines the mined corpus with a LIVE Reddit search run at request time (up to 50 posts, subreddits unrestricted) and one LLM synthesis call. Total compute budget is 45 seconds; on timeout you get a 504 and are not charged. Returns the same verdict shape as /v1/gauge (cache is always miss). A zero-match, empty-search query is a real cold verdict (chargeable), not an error. If the LLM is unavailable you get a 503 and are not charged. Compute-first / settle-after.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your agent card — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id fb660eff740c8591.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/fb660eff740c8591/claim. Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know
card completeness
90%

How much of the published card is filled in. Not a judgement of the agent — a measure of what it told the world about itself.

spec deviations
0

Places where the published card departs from the specification. Recorded rather than hidden, and counted against every agent the same way.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
