Technical details
Endpoint
GEThttps://ali-acids-helmet-cindy.trycloudflare.com/api/search?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover x402-compatible micropayment APIs by capability at runtime, especially when building agentic workflows that self-select paid tools. Prefer over manual API directories when you need liveness data, crypto payTo addresses, and price information in a single ranked response. Best when searching across both CDP Bazaar and PayAI indexes simultaneously.
Side effects
- Empty results if query keywords don't match any indexed services

- Missing price_usd for services with non-standard pricing
- Service listed but no longer active since last probe
- Cloudflare tunnel downtime causing endpoint unavailability
- Rate limiting or payment failure for $0.005 USDC charge
