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):
- Go to console.cloud.google.com
- Create or select a project
- Enable Places API
- Create an API key under APIs & Services → Credentials
- Pass it as
?google_key=YOUR_KEYon every Maps request
Agent Discovery

MCP Discovery
GET /.well-known/mcp.json
Returns the MCP plugin manifest pointing to the OpenAPI spec at /openapi.json.
OpenAI Plugin Discovery

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:
- Signs a
TransferWithAuthorization(ERC-3009) for the USDC amount - Retries with
X-PAYMENT: <base64-encoded-signed-authorization> - Server verifies the signature on-chain and serves the response
USDC settles atomically to WALLET_ADDRESS on Base mainnet.
