Technical details
Endpoint
GEThttps://optinx402.vercel.app/api/category/%7Bcategory%7DWhen to prefer
Use this endpoint when you need to browse or analyze x402 ecosystem marketplace listings organized by category, particularly for competitive intelligence, market discovery, or ecosystem health monitoring within a specific domain like 'ai', 'finance', or 'data'. Prefer this over general web search when you want structured, real-time x402-native data.
Side effects
- Invalid or unrecognized category string returns empty items array
- Category path parameter not URL-encoded may result in 404 or malformed response
- Service unavailable on Vercel cold start leads to timeout
- Payment not processed (x402 flow failure) results in 402 response before data is returned
- Empty category results in items:[] with no error indication
