ToolPick searches every paid x402 resource listed on the public x402 discovery indexes (36,000+ endpoints, merged from the CDP discovery API and the PayAI list) and ranks them for a task by relevance, real 30-day usage (calls and unique payers reported by the index), recency and price, with filters for max price, network (Base, Solana, Polygon, Arbitrum...) and minimum payers. The pick tier live-checks the top candidates (one unpaid request each: do they answer 402 with terms right now, does the price match the listing) and names a best verified pick plus the category price range; the market tier gives sellers and builders the competition and pricing picture for a category (price quartiles, payer-weighted price, top sellers by estimated revenue). Fail-closed: a stale or missing index is refused (not charged) and unverified candidates are never called verified. Paid per call over x402 or with prepaid credits; free preview and remote MCP. Rankings use public x402 index metadata and the index-reported 30-day call and payer counts; listings are self-described by sellers and are not endorsements. A live check only shows that an endpoint answers with x402 payment terms right now, not that its data is good or that the seller is safe. Check terms before paying. ToolPick never pays, holds funds or keys.","url":"https://toolpick.agentgate.workers.dev/v1/market?utm_source=zero.xyz","method":"GET","headers":{},"bodySchema":{"type":"object","$schema":"https://json-schema.org/draft/2020-12/schema","required":["input"],"properties":{"input":{"type":"object","required":["type","method"],"properties":{"type":{"type":"string","const":"http"},"method":{"enum":["GET"],"type":"string"},"queryParams":{"type":"object","required":[],"properties":{"need":{"type":"string","description":"The capability you need, in plain words, e.g. \"solana token safety\", \"web search\", \"pdf to text\", \"hyperliquid funding rates\" (2-200 chars); omit for the whole index"},"limit":{"type":"integer","description":"Rows per list, 1-25 (default 10)"},"network":{"enum":["any","base","solana","polygon","arbitrum","optimism","ethereum","avalanche"],"type":"string","description":"Only resources payable on this network (default any)"}},"description":"Search intents: x402 market data, api pricing research, api market size, x402 seller analytics, api price benchmarks, paid api competition"}},"additionalProperties":false},"output":{"type":"object","required":["type"],"properties":{"type":{"type":"string"},"example":{"type":"object","properties":{"need":{"type":"string"},"tier":{"type":"string"},"index":{"type":"object"},"stats":{"type":"object"},"terms":{"type":"array"},"filters":{"type":"object"},"checked_at":{"type":"string"},"confidence":{"type":"string"},"disclaimer":{"type":"string"},"top_sellers":{"type":"array"},"total_sellers":{"type":"number"},"sources_failed":{"type":"array"},"top_resources_by_payers":{"type":"array"}}}}}}},"responseSchema":{"type":"json","example":{"need":"token safety","tier":"market","index":{"age_s":600,"stale":false,"refreshed_at":"2026-10-23T12:59:10.247Z"},"stats":{"hosts":87,"calls_30d":2646,"price_usd":{"max":1,"min":0.001,"p25":0.01,"p75":0.02,"median":0.01},"resources":287,"est_revenue_note":"calls x listed price; an upper bound (includes sellers testing their own endpoints and crawler payments; resources priced $5+ excluded)","priced_resources":287,"est_revenue_30d_usd":52.57,"price_with_buyers_usd":{"p25":0.005,"p75":0.015,"median":0.01,"payer_weighted_median":0.01},"hosts_with_3plus_payers":34},"terms":["token","safety"],"filters":{"network":"any"},"checked_at":"2026-10-23T13:09:10.247Z","confidence":"high","disclaimer":"Rankings use public x402 index metadata and the index-reported 30-day call and payer counts; listings are self-described by sellers and are not endorsements.
