A simple 4-step HTTP payment flow — no accounts, no subscriptions.

01
Send Request

Client sends a GET or POST request to the endpoint with a query parameter. No API key required.

02
402 Response

Server responds with 402 Payment Required and a WWW-Authenticate header containing payment details.

03
Pay USDC

Client pays USDC to the recipient wallet on Base mainnet and includes the PAYMENT-SIGNATURE header in a retry.

04
Get Response

Endpoint unlocks and returns the AI-generated JSON response. Done — no session, no token, no expiry.
