Callers pay per-request in USDC on Base — no accounts, API keys, or subscriptions needed. ### How It Works x402 is an HTTP-native payment protocol. When a client hits a protected endpoint without paying, the server returns HTTP 402 with payment requirements. The client signs a USDC payment and retries with a payment header. The facilitator verifies and settles the payment, and the server returns the response. ### Confirm wallet is initialized and authed npx awal@latest status If the wallet is not authenticated, refer to the authenticate-wallet skill. ### Step 1: Get the Payment Address Run this to get the wallet address that will receive payments: npx awal@latest address Use this address as the payTo value. ### Step 2: Set Up the Project mkdir x402-server && cd x402-server npm init -y npm install express x402-express Create index.js: const express = require("express"); const { paymentMiddleware } = require("x402-express"); const app = express(); app.use(express.json()); const PAY_TO = "
"; // x402 payment middleware — protects routes below const payment = paymentMiddleware(PAY_TO, { "GET /api/example": { price: "$0.01", network: "base", config: { description: "Description of what this endpoint returns", }, }, }); // Protected endpoint app.get("/api/example", payment, (req, res) => { res.json({ data: "This costs $0.01 per request" }); }); app.listen(3000, () => console.log("Server running on port 3000")); ### Step 3: Run It node index.js Test with curl — you should get a 402 response with payment requirements: curl -i http://localhost:3000/api/example ### paymentMiddleware(payTo, routes, facilitator?) Creates Express middleware that enforces x402 payments. ParameterTypeDescriptionpayTostringEthereum address (0x...) to receive USDC paymentsroutesobjectRoute config mapping route patterns to payment configfacilitatorobject?Optional custom facilitator (defaults to x402.org) ### Route Config Each key in the routes object is "METHOD /path". The value is either a price string or a config object: // Simple — just a price { "GET /api/data": "$0.05" } // Full config { "POST /api/query": { price: "$0.25", network: "base", config: { description: "Human-readable description of the endpoint", inputSchema: { bodyType: "json", bodyFields: { query: { type: "string", description: "The query to run" }, }, }, outputSchema: { type: "object", properties: { result: { type: "string" }, }, }, }, }, } ### Route Config Fields FieldTypeDescriptionpricestringUSDC price (e.g. "$0.01", "$1.00")networkstringBlockchain network: "base" or "base-sepolia"config.descriptionstring?What this endpoint does (shown to clients)config.inputSchemaobject?Expected request body/query schemaconfig.outputSchemaobject?Response body schemaconfig.maxTimeoutSecondsnumber?Max time for payment settlement ### Supported Networks NetworkDescriptionbaseBase mainnet (real USDC)base-sepoliaBase Sepolia testnet (test USDC) ### Multiple endpoints with different prices const payment = paymentMiddleware(PAY_TO, { "GET /api/cheap": { price: "$0.001", network: "base" }, "GET /api/expensive": { price: "$1.00", network: "base" }, "POST /api/query": { price: "$0.25", network: "base" }, }); app.get("/api/cheap", payment, (req, res) => { /* ... */ }); app.get("/api/expensive", payment, (req, res) => { /* ... */ }); app.post("/api/query", payment, (req, res) => { /* ... */ }); ### Wildcard routes const payment = paymentMiddleware(PAY_TO, { "GET /api/*": { price: "$0.05", network: "base" }, }); app.use(payment); app.get("/api/users", (req, res) => { /* ... */ }); app.get("/api/posts", (req, res) => { /* ... */ }); ### Health check (no payment) Register free endpoints before the payment middleware: app.get("/health", (req, res) => res.json({ status: "ok" })); // Payment middleware only applies to routes registered after it app.get("/api/data", payment, (req, res) => { /* ... */ }); ### POST with body schema const payment = paymentMiddleware(PAY_TO, { "POST /api/analyze": { price: "$0.10", network: "base", config: { description: "Analyze text sentiment", inputSchema: { bodyType: "json", bodyFields: { text: { type: "string", description: "Text to analyze" }, }, }, outputSchema: { type: "object", properties: { sentiment: { type: "string" }, score: { type: "number" }, }, }, }, }, }); app.post("/api/analyze", payment, (req, res) => { const { text } = req.body; // ... your logic res.json({ sentiment: "positive", score: 0.95 }); }); ### Using the CDP facilitator (authenticated) For production use with the Coinbase facilitator (supports mainnet): npm install @coinbase/x402 const { facilitator } = require("@coinbase/x402"); const payment = paymentMiddleware(PAY_TO, routes, facilitator); This requires CDP_API_KEY_ID and CDP_API_KEY_SECRET environment variables. Get these from https://portal.cdp.coinbase.com. ### Testing with the pay-for-service Skill Once the server is running, use the pay-for-service skill to test payments: # Check the endpoint's payment requirements npx awal@latest x402 details http://localhost:3000/api/example # Make a paid request npx awal@latest x402 pay http://localhost:3000/api/example ### Pricing Guidelines Use CaseSuggested PriceSimple data lookup$0.001 - $0.01API proxy / enrichment$0.01 - $0.10Compute-heavy query$0.10 - $0.50AI inference$0.05 - $1.00 ### Checklist Get wallet address with npx awal@latest address Install express and x402-express Define routes with prices and descriptions Register payment middleware before protected routes Keep health/status endpoints before payment middleware Test with curl (should get 402) and npx awal@latest x402 pay (should get 200) Announce your service so other agents can find and use it ## Trust - Source: tencent - Verification: Indexed source record - Publisher: 0xRAG - Version: 0.1.0 ## Source health - Status: healthy - Item download looks usable. - Yavira can redirect you to the upstream package for this item. - Health scope: item - Reason: direct_download_ok - Checked at: 2026-05-05T20:39:39.266Z - Expires at: 2026-05-12T20:39:39.266Z - Recommended action: Download for OpenClaw ## Links - [Detail page](https://openagent3.xyz/skills/monetize-service) - [Send to Agent page](https://openagent3.xyz/skills/monetize-service/agent) - [JSON manifest](https://openagent3.xyz/skills/monetize-service/agent.json) - [Markdown brief](https://openagent3.xyz/skills/monetize-service/agent.md) - [Download page](https://openagent3.xyz/downloads/monetize-service)
