{"openapi":"3.1.0","info":{"title":"Agent402: 500+ pay-per-call tools for AI agents over x402 + MPP","version":"2.1.0","description":"The open-source, self-hostable applied layer of Agentic Finance - agents paying and getting paid over x402 and MPP: 500+ machine-payable web tools for AI agents in one place (browser, search, PDFs, images, live data, payment helpers) - the whole catalog is open and runnable yourself. Each priced operation is paid per call over x402 (USDC on Base, Solana, Polygon, Arbitrum, Monad, Celo, Avalanche, Sei, Optimism, Arc, Stellar, or Algorand - or USDG on Robinhood Chain; identity-bound and long-running operations take EVM chains only, and each operation's description names its own rails), or over MPP (Machine Payments Protocol: USDC.e or PathUSD natively on Tempo, USDC on Base or Celo, or a card on routes priced $0.50 or more) - no signup, no API keys - the first request returns HTTP 402 carrying both offers, an x402 or mppx client pays and retries - or free with proof-of-work. Also the open x402 index, Smart Order Router and MPP marketplace. Free discovery: GET /api/pricing, GET /llms.txt. Multi-tool workflows: GET /api/skill-packs.json.","contact":{"name":"Havok Holdings LLC","email":"mike@agent402.tools","url":"https://agent402.tools"},"x-guidance":"Every operation in this document that carries x-price is pay-per-call: request it unauthenticated, read the 402 (x402 PAYMENT-REQUIRED or MPP WWW-Authenticate: Payment), pay and retry. Find the right tool with GET /api/find?q=<task> and read prices at GET /api/pricing, both free (its payment.premiumUsdByNetwork names a chain's settlement premium, added to every price quoted on that chain, and payment.minPriceUsdByNetwork a chain's floor; an operation's x-payment-info carries the premium too); many tools also accept free proof-of-work (GET /api/pow). To call a model, use the metered routes (POST /v1/metered/chat/completions, POST /v1/metered/messages, POST /v1/metered/responses), the default. The 402 quotes this exact request from its own body (the input estimated from its tokens with headroom, plus your max_tokens, at the model's list price plus a fee). On x402, Tempo and credits, settlement never exceeds that quote: an exact payer pays the quote, and an upto payer (where the 402 offers it) or a credits key settles what the answer used; a card payment adds the processor fee. Flat tiers stay as the predictable-price option: one price per call whatever the length, $0.003 to $0.50 (/v1/nano, /v1, /v1/pro, /v1/premium; GET /v1/models lists every model with its tier). Retries: an Idempotency-Key replays a served paid call without a second charge, and a request re-sent with the same signed EVM payment is replayed without one (X-Replayed-Answer: 1)."},"servers":[{"url":"https://agent402.tools"}],"components":{"schemas":{"User":{"type":"object","properties":{"id":{"type":"string"},"name":{"type":"string"}}}},"parameters":{"UserId":{"name":"id","in":"path","required":true,"schema":{"type":"string"}}},"headers":{"IdempotentReplay":{"description":"true when this 200 was replayed from the first answer to the same credential, route and body (an Idempotency-Key, the x402 payment-identifier extension, or a re-sent EVM payment): no handler ran and nothing settled again.","schema":{"type":"string","enum":["true"]}},"ReplayedAnswer":{"description":"1 when the replay was keyed on a re-sent signed EVM payment (same nonce, route and body) with no Idempotency-Key.
