api record

Agent payments have no chargeback. Paddock is pre-payment verification for AI agents. get_market_summary needs no key. Other tools take an api_key argument: a free key is issued with an email at paddock.finance/docs and has a daily limit; paid keys remove it. Tools only read data. Paddock never makes payments and never writes anything on the user's behalf.

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Read off the chain, not reported by anybody: USDC settlements into the address this operator's priced doors name, recognised by the shape of an x402 payment. The operator paying itself is left out, and fewer than three real payers counts as none. The address stands behind 10 doors on this origin, so this is the operator's figure. How it is counted.

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.

  • verify_before_pay 0.25 USDC paid never probed

    Should my agent pay this endpoint right now? Free key - a free pk_free_ key covers it against a shared 10 calls/day; $0.25 per call via x402 beyond it. Over MCP only, 1 free trial call/day is available without a key. CALL THIS BEFORE YOUR AGENT AUTHORIZES ANY x402 PAYMENT. An unpaid GET and POST at query time decode the 402 from the body AND the payment-required header; HTTP 200 is never treated as live. A contract mismatch is route:false and names the field (network, asset, seller, price). Includes independent paid-fulfillment results where available — whether a third party has actually paid this endpoint and got a valid response back, with the settlement hash. Test the result with route === true: the string "inconclusive" is truthy, and it is the one case where you must not pay on our say-so. The bias is deliberate: where evidence is incomplete, verify_before_pay favors inconclusive over a false pass — it will more often decline to clear a good endpoint than clear a bad one. route: true means the live contract matched your expectations — it is not an all-clear on every signal: stale settlement, a circular flag, a payTo divergence, and a failed request pre-flight can each coexist with it, so read the checks block rather than route alone. route_state carries the same verdict as route, always as a string ("true", "false", "inconclusive"), for clients that cannot type a boolean-or-string field. contract_and_request_ok is the narrower combined verdict: true only when route is true AND your own declared request passed pre-flight, false when either is bad, and the string "not_assessed" when a term was never established (usually because you passed no intended_params). Test it with === true; contract_and_request_ok_excludes names the risk categories it is silent on. No success-rate field is returned, deliberately: Paddock observes settlements, not failed calls, so recency and frequency are reported instead. Pass attest: true to also issue a signed, publicly fetchable record of this verdict — returns an attestation id and a URL a third party can verify independently against Paddock's published key.

  • get_market_summary open 35m ago

    How big is agent commerce today? (The citation number.) Keyless - no key, no payment, no rate limit. Returns daily transactions, USDC spend, unique buyer agents, live providers, and top categories by share. Each category's share_of_transactions is its share of CATEGORIZED (attributed) transactions — named categories only, NOT a share of the full-ecosystem daily_transactions total; only the top 6 are returned, so the shown shares sum to <100% by design.

Over MCP only, 1 free trial call/day is available without a key. Every category ranked by opportunity score (high volume, few providers), with concentration and an Open/Tightening/Consolidating/Mature signal, and the published thresholds behind that label.

  • get_provider_revenue open 35m ago

    Who earns the most, and how much of the market can that answer see? Paid - $0.99 per call via x402, or a Builder / Pro Agent key. Over MCP only, 1 free trial call/day is available without a key. Resolved by payTo wallet attribution, not by counting events. ATTRIBUTED universe only, never the full-ecosystem census: facilitator pass-through and circular-flagged wallets are excluded from the leaderboard; unresolved wallets are not dropped — they surface as one explicit unattributed row (transaction share only, no dollar figure exists for them). Also reports whether the recipient list was complete on every aggregated day, and flags (retroactive_exclusion_caveat) any day before 2026-07-28 where a wallet added to the exclusion lists afterward could not be retroactively re-checked.

  • get_liveness unknown never probed

    Was this domain up at last night's probe, per someone who isn't the seller? Free key - a free pk_free_ key covers it against a shared 10 calls/day; $0.001 per call via x402 beyond it. Over MCP only, 1 free trial call/day is available without a key. Per-domain 7-day share of probes that succeeded, latency p50/p95, sample counts, and last-probe time — including domains with no payment history at all. Sourced from an independent third-party monitoring feed, captured NIGHTLY: this is a daily series, not a live probe — for a check taken at query time use verify_before_pay. up is 7-day share of probes that succeeded >= 0.95 across every probed endpoint on the domain.

    Is this facilitator's volume real, or is it paying itself? Paid - $0.99 per call via x402, or a Builder / Pro Agent key. Over MCP only, 1 free trial call/day is available without a key. Wash/circular-settlement signal per facilitator: flagged clusters, flagged volume and share, self-funding percentage, detection date. Methodology public (v0.1).

    Which provider in this category should my agent pick? Paid - $0.02 per call via x402, or a Builder / Pro Agent key. Over MCP only, 1 free trial call/day is available without a key. Ranks a category by reliability (7-day share of probes that succeeded), reputation (unique buyers), and price, returning every input so the score can be checked. The composite formula is published in the route and in the docs, and Paddock does not sell positions in this ranking. Valid categories: llm, data, search, infra, content, markets, payments, comms (aliases accepted).

  • get_token_metrics unknown never probed

    Is today's number a real move or ordinary noise? Free key - a free pk_free_ key covers it against a shared 10 calls/day; $0.01 per call via x402 beyond it. Over MCP only, 1 free trial call/day is available without a key. Paddock's own first-party series — the same chart data the public /charts page reads — queryable by metric and date range. Metrics: spend_share_over_time, daily_transactions, category_concentration, new_services, liveness_score, aci. The aci metric returns the Agent Commerce Index series, which is SUSPENDED (ADR 0006): existing prints are retained and served, no new prints are computed, so that series does not advance. This is Paddock's series, not token prices; third-party token market data is deliberately not resold here.

_ 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.

[![measured by brick.blue](https://brick.blue/api/v1/agents/857734cd3ec52d42/badge.svg)](https://brick.blue/agent/857734cd3ec52d42)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
