Agent Tools

The open discovery layer for x402 services — 22363 verified service entries, LLM-ranked recommendations via /api/v1/ask, and service cards with payment, call, and quality metadata.

Add your API

Aggregated from public x402 sources — x402scan, awesome-x402, Coinbase CDP Bazaar, pay-skills PRs — plus our own crawling and provider self-submissions. Every entry is de-duplicated across sources, liveness-probed (health + on-chain payment demand), and passed through ingestion filters (bare-IP / dead-host removal) before listing — distilling tens of thousands of raw endpoints down to 22363 verified services.
