How this service works
Ranks live x402 endpoints for a task such as 'web search', 'token price' or 'pdf to text'. Returns up to 10 endpoints ranked by text match, 7-day liveness probes and on-chain USDC payers with farmed wallets removed. Not charged when nothing matches.
Output
A ranked list of up to 10 live x402 endpoints matching the task query. Each result includes the endpoint URL, a relevance/liveness score derived from text match and 7-day probe history, on-chain USDC payer counts, and price per call. Returns empty when no endpoints match.
Example use cases
Cheapest live PDF-to-text service
“Find me up to 5 x402 endpoints that can convert PDF to text, only on Base (eip155:8453), and no more than $0.01 per call — I want whichever ones are currently live and most used on-chain.”
Token price feed discovery
“I need a token price API that accepts x402 payments. Search for 'token price' and show me the top 3 ranked by liveness and on-chain usage.”
Picking a web scraping endpoint
“Can you find me the best x402 endpoints for web scraping? Give me up to 10 results and rank them by how active they've been in the last 7 days.”
Technical details
Endpoint
GEThttps://finder.marknetic.co.uk/find?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover which x402-compatible, USDC-payable APIs exist for a given task at runtime — especially when the desired capability is unknown ahead of time or the agent wants to compare liveness, cost, and on-chain adoption across candidates before committing to a call.
Side effects
- No endpoints match the task description — returns empty list at no charge
- Invalid CAIP-2 network string causes filtering to fail or return no results
- max_price too low excludes all available endpoints
- limit parameter out of 1–10 range may be ignored or cause an error
- Task description too vague returns low-relevance or mismatched endpoints
