Endpoints

GET/supportedPayment kinds, networks, and settlement signers.

POST/verifyChecks a signed payment payload against requirements: signature, expiry, balance, on-chain simulation.

POST/settleRe-verifies, then broadcasts the transfer. The facilitator pays gas; funds move payer to merchant.

Use it from the x402 SDK

import { x402HTTPResourceServer } from '@x402/core/http';

// Point your resource server at the Mesh facilitator:
const server = new x402HTTPResourceServer({
  facilitator: { url: 'https://facilitator.meshgateway.co' },
  routes: { 'GET /report': { price: '$0.01', network: 'eip155:8453' } },
});

Or straight over HTTP

Settlement signer

Settlements are broadcast from this wallet on every supported chain. It pays gas only; it can never move funds without a payer's signed authorization.
