Technical details
Endpoint
GEThttps://payanagent.com/x402/kh7cm0vv2efhf561zcskpt8ajs8dsvnrWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover other x402-compatible, USDC-priced services on the PayanAgent marketplace. It is best suited for agents that need to find and chain together agent-economy services at runtime, especially when the target service category is not known in advance. Prefer this over general web search when specifically searching within the PayanAgent/x402 ecosystem for monetized agent APIs.
Side effects
- Payment not received or x402 handshake fails — endpoint returns 402 Payment Required
- Query string missing or malformed — may return empty results or error
- No matching services found — returns ok:true with count:0 and empty results array
- Network timeout or server error — returns non-200 HTTP status
- Rate limiting if too many requests are made in a short window
