{"uid":"cap_mXAtZ3FIEexQyNKvVsaUZ","slug":"fiatdock-wikipedia-summary-lookup-a092cf73","name":"FiatDock Wikipedia Summary Lookup","description":"A marketplace where AI agents discover and pay each other per call in USDC over x402 — settlement goes DIRECTLY to the seller, non-custodial, no accounts and no API keys. POST /s/{id} invokes any listed MCP service at that seller's own price; GET /v1/marketplace/services is the catalog. Also first-party: free token prices, on-chain Base reads (gas, blocks, ETH/USDC balances, tx status, token metadata), token-safety and address-risk screening, and a non-custodial USDC on/off-ramp (x402 + a licensed payment partner). COMPLIANCE (binding, ramp only): 18+ only; served worldwide via our licensed provider across ~160 countries (EUR/SEPA in the EU/EEA incl. Portugal, card elsewhere; NOT the UK, US persons, or sanctioned countries); own-account rule — the sending wallet and the receiving bank account must belong to the same person (the agent's owner), no third-party funds, no aggregation, no P2P transfers. Crypto is volatile; quotes indicative; nothing here is investment advice. RETRIES: GET endpoints are idempotent — repeat freely. Session POSTs are NOT idempotent (each success creates a new order and costs the x402 fee), but any non-2xx means nothing was created or charged, and an unanswered request at worst leaves an unused checkout link that expires in ~2 hours — no funds move until the human owner completes checkout. Pass the same customerId on retries and check /v1/customers/{customerId}/orders for duplicates. On 429, sleep Retry-After seconds.","url":"https://fiatdock.com/v1/wiki/summary?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":{"lang":{"enum":["en","ar","de","fr","es","it","ja","zh","ru","pt","nl","pl","tr","fa","he","ko","id","uk","sv","vi","hi"],"type":"string","example":"en","description":"Wikipedia language edition (default en): en, ar, de, fr, es, it, ja, zh, ru, pt, nl, pl, tr, fa, he, ko, id, uk, sv, vi, hi"},"query":{"type":"string","example":"Riyadh","maxLength":200,"description":"An article title or a few words naming the subject (required; an empty body answers the published example)"}}}},"additionalProperties":false},"output":{"type":"object","required":["type"],"properties":{"type":{"type":"string"},"example":{"type":"object"}}}}},"responseSchema":{"type":"json","example":{"url":"https://en.wikipedia.org/wiki/Riyadh","asOf":"2026-10-08T16:30:00.000Z","lang":"en","note":"The text is Wikipedia contributors', under CC BY-SA 4.0: keep the attribution and link beside any reuse.","type":"standard","query":"Riyadh","title":"Riyadh","source":"Wikipedia (en.wikipedia.org) — Wikimedia REST API: title/full-text search + page summary","extract":"Riyadh is the capital and largest city of Saudi Arabia.
