Quick Install

Automated & IDE Setup

Copy the AI prompt to install this server into Claude Code, Cursor, or another agent — or use 1-click editor setup below.

One-click editor setup isn’t available for this listing yet — we don’t have a confirmed install command, and we’d rather show nothing than point your editor at the wrong package or host. Follow the project’s own setup instructions, linked above.

Manual Client & Custom JSON ConfigExpand JSON ▾

No confirmed setup config for this listing yet. We only publish a config block when the install details come from the project itself — its README, its docs, or a verified owner. We haven’t found those for mgo, and we’d rather show nothing than a guess you’d paste into your client. Follow the project’s own setup instructions for the current steps.

Endpoints

Endpoint	Payment	Description
`GET /gas/demo`	Free	Raw gas prices only (10/hr rate limit)

`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

server.ts

// 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");
