How this service works
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.
Output
Returns a JSON object with the article title, a plain-text extract (paragraph-length summary), the canonical Wikipedia URL, a thumbnail image URL, geographic coordinates (where applicable), Wikidata ID, last-modified timestamp, CC BY-SA 4.0 license info, attribution string, language code, matched article type, and up to several related article titles for disambiguation.
Example use cases
Enriching a travel itinerary with local facts
“For each city on my itinerary — Rome, Kyoto, and Buenos Aires — grab the Wikipedia summary and coordinates so I can add quick context cards to the trip plan.”
Answering a factual question about a person
“What does Wikipedia say about Marie Curie? Give me the short summary and the link to the full article.”
Multilingual content enrichment
“Get me the Wikipedia summary for 'Artificial intelligence' in Japanese — I need the extract and the article URL for a localized briefing doc.”

Endpoint
GEThttps://fiatdock.com/v1/wiki/summary?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, structured Wikipedia summary with rich metadata (coordinates, thumbnail, Wikidata ID, license info) across 20 language editions, billed per-call in USDC with no API key required. Prefer it over raw Wikipedia REST API calls when operating in an x402 pay-per-call agent environment, or when you need a normalized, schema-consistent response rather than raw Wikimedia JSON.
Side effects
- Query does not match any Wikipedia article — returns a not-found or empty result
- Ambiguous query matches multiple articles — response includes otherMatches array with candidates
- Wikipedia API rate limit or upstream outage — upstream error propagated
- Empty or blank query string — endpoint returns the published example response (Riyadh) rather than an error
- Unsupported language code — request rejected by schema validation
