x402 API — pay-per-call exchange data

The same data that powers Rebatify, sold to AI agents pay-per-call in USDC over Coinbase’s x402 standard. No account, no API key — your agent pays $1.00 USDC on Base per call and gets structured JSON back.

How it works

Every endpoint speaks x402. Hit it with no payment and you get 402 Payment Required plus a challenge; an x402-capable client (x402-fetch, Base MCP, or any Bazaar consumer) signs a one-shot USDC authorization and retries. The facilitator settles on-chain and pays the gas — your agent never needs ETH, just USDC. Funds land directly in our receiving wallet; we never custody or hold a key for this.

Most endpoints accept filters so you buy only the slice you need, and a fields array to return only the columns you want. The full machine-readable menu (with each endpoint’s input schema) is free at /api/x402, and every endpoint is discoverable in the Coinbase Bazaar (merchant 0xA9BD0171cf284F338a1925E352DB4a7D4CAed0b8).

Call it

# 1. The free catalog (no payment) — list every endpoint + its input schema
curl https://www.rebatify.net/api/x402

# 2. Call a paid endpoint with any x402 client (x402-fetch, Base MCP, …).
#    Without payment you get HTTP 402 + a PAYMENT-REQUIRED challenge;
#    your client signs a USDC payment and retries automatically:
import { wrapFetchWithPayment } from '@x402/fetch';
const pay = wrapFetchWithPayment(fetch, client); // client holds your wallet
const res = await pay('https://www.rebatify.net/api/x402/best-rebate', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({ limit: 5, fields: ['payback', 'takerFee'] }),
});
const data = await res.json(); // top rebate exchanges — paid $1 USDC on Base
