createCdpFacilitatorClient

function createCdpFacilitatorClient(args?: CdpFacilitatorClientArgs): HTTPFacilitatorClient;

Defined in: facilitator.ts:180 Creates a CDP-authenticated x402 facilitator client. The returned client is pre-configured with the CDP hosted facilitator URL and CDP JWT-based authentication. It implements the HTTPFacilitatorClient interface from @x402/core/server and can be passed directly to x402ResourceServer as a drop-in replacement for a self-hosted facilitator. Credentials are resolved in order: explicit args → CDP_API_KEY_ID / CDP_API_KEY_SECRET environment variables.

Parameters

args?

CdpFacilitatorClientArgs Optional credential overrides.

Returns

HTTPFacilitatorClient A configured HTTPFacilitatorClient ready for use with x402ResourceServer.

Throws

If neither explicit args nor environment variables provide credentials.

Examples

Drop-in replacement for a self-hosted facilitator:

import { createCdpFacilitatorClient } from "@coinbase/cdp-sdk/x402";
import { x402ResourceServer } from "@x402/core/server";
import { ExactEvmScheme } from "@x402/evm/exact/server";

// Set CDP_API_KEY_ID and CDP_API_KEY_SECRET in your environment
const facilitator = createCdpFacilitatorClient();

const server = new x402ResourceServer(facilitator)
  .register("eip155:8453", new ExactEvmScheme());

Explicit credentials:

const facilitator = createCdpFacilitatorClient({
  apiKeyId: "my-key-id",
  apiKeySecret: "my-key-secret",
});
