x402 Payment Harness
https://github.com/rplryan/x402-payment-harness 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."
Python library + CLI for x402 without Coinbase CDP wallet. Works with any Ethereum EOA. Full HTTP 402 -> EIP-712 sign -> X-PAYMENT header flow. `pip install x402-payment-harness`.
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.
