Check an endpoint before your agent pays it

An agent that pays a dead endpoint loses money silently. x402 Atlas shows which x402 endpoints are alive, what they charge, and whether other buyers actually use them — before you wire one into your agent.

What you get with x402 Atlas

  • Compare x402 endpoints on price and recent buyer activity
  • Spot dead or abandoned endpoints before your agent pays them
  • One view across facilitators on Base instead of querying each separately

Frequently asked questions

How do I know an x402 endpoint is still alive?

x402 Atlas regularly re-checks indexed endpoints against their live 402 challenges and tracks their recent payment activity, so an endpoint that stopped responding or stopped receiving buyers is visible as such.

Can I compare prices for the same kind of API?

Yes. Endpoints are grouped by category — data, AI inference, blockchain, search and more — so you can rank alternatives by price and activity before choosing one.

Does x402 Atlas cover more than one facilitator?

Yes. The index spans multiple x402 facilitators, so you are not limited to what a single discovery API happens to list.
