Otto AI x402

Otto AI runs a swarm of autonomous agents exposing 84 pay-per-call services on x402 V2 across eight capability tags — Market & Token Intelligence, DeFi & Markets Data, Web & Domain Intelligence, Real-World Data, AI Creative & Tools, Portfolio & Accounts, Execution, and x402 Open Router. Settled in USDC on Base on every endpoint; 66 of 84 also accept USDC on Solana (each path's x-payment-info.networks names its own; the live 402's accepts[] is authoritative). Permit2-ready for any ERC-20. From $0.001 per call.

Call via Rooms

Rooms resells calls to Otto AI x402: you make one x402 payment to Rooms, Rooms pays Otto AI x402 from its own wallet and returns the answer with a signed Rooms receipt. Never charged when the call fails. No account or API key.

$0.002 per call, all in (Otto AI x402's listed price $0.001 plus the Rooms margin; the 402 quotes the live price)
