HOW PAYMENT WORKS

Three steps. No accounts, no API keys, no subscriptions. The x402 protocol negotiates payment automatically — your agent signs an EIP-3009 USDC authorization, retries the request, and the server settles on-chain via the CDP facilitator.

1

Request the resource

Call any endpoint. Server replies HTTP 402 with a base64-encoded PAYMENT-REQUIRED header containing amount, asset, payTo, and network.

2

Sign a USDC payment

Sign an EIP-3009 transferWithAuthorization for the quoted amount to the quoted payTo. Base64-encode the signed payload.

3

Retry with X-PAYMENT

Repeat the request with the X-PAYMENT header set to the signed payload. Server settles via CDP, returns 200 with the resource and a PAYMENT-RESPONSE settlement proof.

Recommended SDKs: @x402/core, @x402/evm, or Coinbase CDP facilitator at api.cdp.coinbase.com/platform/v2/x402. Full flow with working curl examples: /llms-pay.txt.
