USE WHEN an agent needs a paid API or data service it can call and pay per request with x402, and wants the ones with evidence behind them first. Find a paid API/data service an agent can call and pay per request with x402: market data, onchain data, web data, search, inference, security checks, identity lookups, dev tools and more. Describe the need in plain words; optional category, chain and max_price_usd narrow it. RULE ENFORCED: results are ranked by what Sato Hub observed, never by what a seller says about itself and never by anything paid to us. Order: (1) x402-style payments to the payout address on Base in the last seven days from several outside payers, not machine noise (counted when the transaction carries a signed USDC authorization, EIP-3009, the settlement x402's exact scheme uses; some non-x402 gasless sends use it too); (2) the listed URL answered HTTP 402 with a payment payload when we asked; (3) everything else, unknown before no. All USDC received at a payout address is context only and never ranks. Ties go to the lower per-call price. Each hit carries both readings with their dates and method, and links to the one canonical page for its payout address. `unknown` means we hold no reading, never that the service failed. A price is what the seller registered, not a charge we observed; `price_usd` appears only where the asset is USDC on Base or Solana. A hit is a description of what was observed, not an endorsement, and nothing here pays for or calls a service. NO HIT IS INVENTED: when nothing matches, the answer says so and names how to broaden (fewer words, drop a filter, another category). Returns (json): { hits: [{ url, network, chain, description, category, price_usd, merchant: { slug, display_host, pay_to, answers_402, payments, claimed_at, is_ours }, sato_url }], matched, capped, match_mode, evidence_as_of, ranking, guidance, unavailable }. `merchant.payments` carries the x402-style reading (the x402_* fields, which rank) and, as context only, the all-USDC reading. `sato_url` is the canonical page for the payout address. Read-only. Example: { need: "token prices", chain: "Base", max_price_usd: 0.01 }
