This specific endpoint (`GET /api/x402/resources`) returns a paginated list of all indexed x402-protected resources. It supports filtering by chain (Base or Solana) and pagination via `page` (0-based) and `page_size` (1–100, default 10) query parameters. Each call costs a fixed $0.01 USD micropayment via the x402 protocol.\n\nThe endpoint is part of a broader x402scan API suite that includes wallet/merchant/facilitator analytics, full-text resource search, registry management, and a USDC send endpoint. Data endpoints are priced at $0.01–$0.02 per request, while registry write endpoints use SIWX wallet authentication and are free. The API is documented via an OpenAPI 3.1.0 spec served from the origin.\n\nNote: During probing, the endpoint at the cataloged URL (`/api/data/resources`) returned 404, while the OpenAPI spec defines the resource listing at `/api/x402/resources`. The correct canonical path appears to be `/api/x402/resources`. The x402scan dashboard shows active ecosystem stats (97K+ transactions, $17K+ volume in 24 hours at time of crawl), indicating the platform is actively used.","tags":[],"capabilities":["x402-resource-listing","pagination","chain-filtering","x402-micropayment","base-chain","solana-chain","resource-discovery","x402-registry"],"categories":["search","blockchain","analytics"],"synonyms":["x402 resource index","x402 endpoint directory","x402 API catalog","x402 resource registry","x402 protocol explorer","x402 resource search","payment protocol directory"],"warnings":["The cataloged endpoint URL (/api/data/resources) returned 404 on both GET and POST.
