An HTTP API paid for in USDC on base. No account, no API key, no subscription. Prices start at $0.02 per call.

Pay by signed x402 authorization, or by plain USDC transfer from any wallet. An unpaid request answers with HTTP 402 and tells you exactly what to send.

How to pay

x402

Sign an EIP-712 USDC TransferWithAuthorization and send it in the X-Payment header. Verified offline, so no transaction is needed before the request. This is the rail for agents.

Direct transfer

Send USDC from any wallet, then put the transaction hash in the X-Payment-Tx header. This is the rail for people, who cannot produce a signed envelope but can send a payment.
