MGO — Multi-chain Gas Optimizer

An x402-native API that compares real-time gas prices across up to 9 EVM chains and recommends the cheapest one. Built for trading agents, DeFi bots, and any AI agent that needs to optimize transaction costs.

Quick Start

bash

# 1. Install dependencies
npm install

# 2. Set environment variables
cp .env.example .env

Endpoints

Endpoint	Payment	Description
`GET /gas/demo`	Free	Raw gas prices only (10/hr rate limit)
`GET /gas/basic`	$0.001 USDC (x402)	4-chain comparison + recommendation + savings
`GET /gas/premium`	$0.002 USDC (x402)	9-chain full comparison
`GET /llms.txt`	Free	AI agent discovery file
`GET /health`	Free	Server health check

Payment Flow (x402 Protocol)

GET /gas/basic or /gas/premium → 402 response with payment requirements
Client signs EIP-712 USDC authorization (using x402-axios or x402-fetch)
Resend with X-PAYMENT header → facilitator verifies → data response → on-chain settlement

javascript

// 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");
