x402.direct -- Service Directory
The x402.direct API is a directory of x402-enabled services. It indexes services that accept x402 payments (HTTP 402 + crypto) and provides search, browsing, and trust scoring.
Base URL: https://x402.direct
Endpoints
1. Search (Paid -- $0.001 via x402)
GET /api/search?q=<query>
Full-text search across all indexed services. Results ranked by blended text relevance + trust score. Protected by x402 middleware -- first request returns HTTP 402, re-send with payment proof.
{"query":"weather api","count":3,"results":[{"id":42,"resourceUrl":"https://example.com/api/weather","description":"Real-time weather data for any location","category":"weather","provider":"example.com","network":"base-mainnet","price":"1000","priceUsd":"0.001","scoutScore":85,"scoutVerdict":"safe","relevance":0.3214,"score":58.11}]}
x402 payment flow:
Send GET to /api/search?q=... with no payment header.
Server returns HTTP 402 with payment details in the response body (price, network, payTo address, facilitator URL).
Pay $0.001 USDC on Base (via agent wallet or Coinbase Agentic Wallet).
Re-send the same request with X-402-Payment: <proof> header.
Server verifies payment via facilitator and returns search results.
If using an x402-aware HTTP client (e.g., x402 npm package), the payment is handled automatically:
