}'Machine-readable discovery files so your agent can find and use these services autonomously.
Discovery index — short overview of all services and links.
Complete API reference in plain text. Full schemas, examples, errors.
Machine-readable JSON catalog with endpoints, pricing, and schemas.
Protocol-level discovery for x402-aware clients.
// 1. Discover services
const catalog = await fetch("https://x402tools.xyz/agents.json").then(r => r.json());
// 2. Find the right tool
const qr = catalog.services.find(s => s.name === "qr-generator");
// 3. Call it (x402 client handles payment automatically)
