Tiers

Endpoints

Payment Flow (x402 Protocol)

  1. GET /gas/basic or /gas/premium → 402 response with payment requirements
  2. Client signs EIP-712 USDC authorization (using x402-axios or x402-fetch)
  3. Resend with X-PAYMENT header → facilitator verifies → data response → on-chain settlement
// Client example (x402-axios)
const { withPayment } = require("x402-axios");
const client = withPayment(axios.create(), walletClient);
const response = await client.get("https://api.mgo.chain-ops.xyz/gas/basic");
