x402 — Pay per call, no account

Open protocol for machine payments. Your agent sends a request, gets HTTP 402 with payment terms, signs a USDC transfer from its wallet, retries — and receives the result. No API key, no checkout.

1. Request

POST /v1/extract without API key → 402 + PAYMENT-REQUIRED header

2. Sign

Agent wallet signs EIP-3009 USDC authorization (micro-payments from ~$0.001)

3. Retry

Same request + PAYMENT-SIGNATURE → 200 + result + PAYMENT-RESPONSE receipt

Agents: prefer free API key or testnet x402 unless your wallet is already funded on Base.
