Technical details
Endpoint
POSThttps://barry-placement-calling-showers.trycloudflare.com/api/search?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to discover x402-compatible micropayment APIs by capability keyword, especially when you want merged coverage of both CDP Bazaar and PayAI indexes simultaneously with liveness and pricing data in a single call. Prefer this over browsing individual registries manually or calling the /stats endpoint when you need ranked, queryable results for a specific capability.
Side effects
- Empty results if query keywords don't match any indexed service descriptions
- Stale liveness data if probes haven't run recently (liveness may show 'unprobed')
- Temporary Cloudflare tunnel unavailability causing connection errors
- Low relevance scores if query is too broad or too niche
- Payment failure (402) if $0.005 USDC not sent correctly with request
