SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Building API-driven services often requires custom monetization, billing, and access control. This skill provides an out-of-the-box x402-based payment server to monetize endpoints and charge per request without creating complex subscriptions or accounts.

Core Features & Use Cases

  • Protects API endpoints using the x402 payment protocol to require per-request payments.
  • Supports multi-route pricing configuration and payments on the Base network.
  • Enables rapid experimentation and deployment of paid APIs for developers and service providers with no account provisioning.

Quick Start

Install Express and x402-express, create a simple Express server, and enable a protected endpoint to start monetizing your API.

FAQPage Schema
How do I monetize an Express API endpoint with per-request payments?▼

You can monetize Express API endpoints with per-request USDC payments by implementing the x402-express middleware, which validates and settles transactions on the Base network before delivering API responses.

What is the x402 payment protocol for web services?▼

The x402 payment protocol enables paid web services by validating and settling USDC payments on the Base network before an API delivers its response, eliminating the need for custom billing or account provisioning.

Can I configure different pricing for individual API routes using x402?▼

Yes, the x402 protocol supports multi-route pricing configuration, allowing you to apply and set specific per-request USDC costs for each protected Express endpoint on the Base network.

Do I need a Node.js environment to charge for API access with x402?▼

Yes, implementing the x402 402 payment flow requires a Node.js environment along with the Express framework and the x402-express package to validate and settle USDC payments.

How does the x402 protocol handle API access control without user accounts?▼

The x402 protocol handles API access control by validating and settling per-request USDC payments on the Base network before the Express server delivers its response, bypassing the need for account provisioning.
