rothy Intelligence API

An x402-powered intelligence API for Shopify, Amazon, and Google Maps data. AI agents pay per call in USDC on Base — no signup, no API keys, no human in the loop.

What This Does

Free endpoints: GET /health, GET /.well-known/mcp.json, GET /openapi.json

How x402 Payment Works

x402 is a protocol for machine-native micropayments using HTTP 402. No accounts, no rate-limit keys, no billing — agents pay per call in USDC on Base.

Flow:

Agent → GET /shopify/analyze?url=example.myshopify.com
Server → 402 Payment Required
         X-PAYMENT-REQUIRED: {"price": "$0.08", "network": "base", ...}

Agent → signs USDC TransferWithAuthorization (ERC-3009)
Agent → GET /shopify/analyze?url=example.myshopify.com
        X-PAYMENT: <signed-payment-header>

Server → verifies payment on Base
Server → 200 OK + intelligence data

Agents need a funded Base wallet with USDC. USDC settles directly to the server wallet — no intermediary, no escrow.

Getting a Google Places API Key

Maps endpoints require your own Google Places API key (the server never stores it):

1. Go to console.cloud.google.com

2. Create or select a project

3. Enable Places API

4. Create an API key under APIs & Services → Credentials

5. Pass it as ?google_key=YOUR_KEY on every Maps request

Agent Discovery

x402scan

Agents discover x402-enabled APIs via x402scan. The server returns proper x402 headers on every 402 response.

MCP Discovery

GET /.well-known/mcp.json

Returns the MCP plugin manifest pointing to the OpenAPI spec at /openapi.json.

OpenAI Plugin Discovery

GET /.well-known/ai-plugin.json

Compatible with ChatGPT plugin discovery format.

Running the Server

Setup

npm install
cp .env.example .env
# Edit .env: set WALLET_ADDRESS to your Base USDC wallet

Development

npm run dev

Production

npm run build
npm start

Environment Variables

WALLET_ADDRESS=0x...   # Your USDC-receiving wallet on Base (required)
PORT=3000              # Default: 3000
NODE_ENV=production

x402 Payment Flow (Technical)

When an agent makes a request without payment:

HTTP/1.1 402 Payment Required
X-PAYMENT-REQUIRED: {
  "version": "1",
  "price": "$0.08",
  "network": "base",
  "payTo": "0xYourWalletAddress",
  "asset": "USDC"
}

The agent:

1. Signs a TransferWithAuthorization (ERC-3009) for the USDC amount

2. Retries with X-PAYMENT: <base64-encoded-signed-authorization>

3. Server verifies the signature on-chain and serves the response

USDC settles atomically to WALLET_ADDRESS on Base mainnet.
