How this service works
Seven account-free paid tools for source integrity, x402 catalog search, preflight, liveness, routing, price drift, and batch verification.
Output
A JSON object containing a list of matching endpoints (each with resource URL, price in USDC, description, network chain ID, and discovery sources), per-catalog metadata showing how many results each upstream catalog returned and their latency, the total number of unique results, and the search schema version used.
Example use cases
Discovering data enrichment APIs
“Search the x402 catalog for any endpoints that can do company data enrichment or business information lookup — show me the top 10 results and their prices.”
Finding image generation tools
“Can you search across x402 catalogs for paid APIs that do image generation from a text prompt? Show me up to 15 results.”
Locating email validation services
“I need an API that validates email addresses — search the x402 catalog for anything matching email validation and give me the top 5 options.”
Technical details
Endpoint
GEThttps://bj7e26lfpo4fthvr35hczdipby.srv.us/v1/x402-searchWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover which x402 paid APIs exist for a given capability at runtime, especially when the target service is not already known. It aggregates multiple x402 catalogs (bazaar, toll402, etc.) in a single call, making it more comprehensive than querying any single catalog. Prefer this over hardcoded endpoint lists when the space of available x402 tools is evolving or unknown.
Side effects
- Missing required query parameter 'q' returns a 400 or schema validation error
- Payment not provided or insufficient USDC causes a 402 Payment Required response
- Upstream catalogs (bazaar, toll402) may be unavailable, returning partial or empty results
- Limit parameter out of range (outside 1-25) may be rejected or clamped
- Query too broad may return up to 25 low-relevance results requiring further filtering
