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.
