Payzum x402
https://payzum.com/x402/ Our Verdict
A human read this entry. That is the one thing true of everything on the list. Beyond that: this sits on a shelf for libraries, guides and community resources. There is no payable endpoint here, so we never asked it for an HTTP 402 and it makes no claim to speak the protocol. It was publicly reachable when we checked. None of it is a delivery test. We have not paid for this and graded what came back, so read it as "we checked what is stated above," never as "this is worth the money."
Hosted no-code x402 proxy that puts a per-call USDC price on Base in front of an existing HTTP API, verifies payment through an external facilitator (currently Coinbase's) and forwards the paid call to the origin with its stored API credential.

Rater Grades
No independent rater grade published for this entry yet. What we publish is above: who read it, and whether its endpoint answered on a date we can show. Neither is a measurement of what it returns after payment.
