{"uid":"cap_CPQFCj72uI8vEhibfIv-i","slug":"fiatdock-hacker-news-search-front-page-d5fea1bd","name":"FiatDock: Hacker News Search & Front Page","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/news/hackernews?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":{"sort":{"enum":["relevance","date"],"type":"string","example":"relevance","description":"relevance (text match, then points) or date (newest first); default relevance"},"type":{"enum":["story","comment","ask_hn","show_hn","front_page"],"type":"string","example":"story","description":"story, comment, ask_hn, show_hn or front_page; default story with a query, front_page without one"},"limit":{"type":"integer","example":20,"maximum":50,"minimum":1,"description":"How many items, 1-50 (default 20)"},"query":{"type":"string","example":"x402","maxLength":200,"description":"Words to search for, as written (no typo matching; \"quotes\" for a phrase, -word to exclude).
