What it does

x402scan is an analytics dashboard and block explorer for the x402 payment protocol ecosystem. The `/api/data/merchants` endpoint is a paywall-protected API that returns data about merchants (servers) participating in the x402 network. The parent application tracks global x402 statistics including transaction counts, volume, buyer/seller counts, and top servers across chains like Base and Solana, with facilitators including Coinbase, PayAI, Corbits, Polymer, and Virtuals Protocol.

The endpoint responds with HTTP 402 on unauthenticated GET requests, confirming it is live and follows the x402 protocol. However, the 402 challenge body returned is empty (`{}`), which means the specific payment terms (price, token, chain, payTo address) are not available from the probe. No OpenAPI schema, dedicated API documentation, or pricing page exists — the `/docs`, `/api`, `/pricing`, and `/README` paths all return 404.

Based on the dashboard's homepage, x402scan v2 tracks approximately 89.68K transactions and $424.55K in volume over 24-hour windows, with ~9.47K buyers and ~550 sellers. The merchants endpoint likely returns structured data about these servers, but without documentation or a sample response the exact schema is unknown.

The endpoint is live (returns 402) but the challenge body is empty, there is no API documentation, no OpenAPI schema, no pricing information, and no example responses. The exact data schema and payment terms are unknown, making this effectively a stub listing.

Warnings

  • —Empty 402 challenge body — payment terms (price, token, chain, payTo) are not discoverable from the probe
  • —No API documentation found; /docs, /api, /pricing, /README all return 404
  • —No OpenAPI or schema available — response format is unknown
  • —This appears to be a Vercel preview deployment (URL contains hash), not a stable production URL
  • —Price per request is unknown
