The x402 ecosystem, measured

x402 lets a service charge per request over plain HTTP. Anyone can declare that they take it; far fewer answer a payment request, and fewer still get paid. These pages measure each step on its own, say how, and date every reading. A blank is “unknown”, never “failed”.

Where to look

• x402 merchants

  The sellers behind the catalogue, one per payout address, in the order the evidence puts them: who answers, who gets x402-style payments from outside buyers, what they list and at what price.

• x402 doctor

  Selling over x402? Paste an endpoint and see what a paying client would meet, check by check. Nothing is paid.

• Facilitators

  Who broadcasts x402 settlements on Base, with the public evidence behind each address.

• Declared endpoints that answer

  A daily probe of every endpoint that declares x402 support. The probe reads a 402 and stops; it never pays.

• x402 endpoints that answer

  How many x402 payment endpoints actually answer a payment request?

• x402 price per call

  What does an x402 call actually cost?

• x402 facilitator throughput

  How many x402 settlements do facilitators send per day?

Appearing in an index is not an endorsement. Each page states what was measured, on which chain and on which date; none of them measures whether a paid call returns what it promised. House rules
