the402 x402 endpoint directory

MCP servers, called rather than listed · we called 16,923 of them · search their tools

Every x402 endpoint we can find, each one called to see what it actually answers and what it quotes. Other directories list what providers claim. This one reports what the endpoint did when we asked it, and says plainly where we could not tell.

Last verified 2026-09-28. We parse the payment challenge, we do not complete a payment.
