Api Endpoint

x402-payment-debug

Your 402 envelope can pass every static check and still not get you paid. We build a real signed payment at your listed price and submit it to the CDP facilitator verify endpoint, which checks signature, requirements and the on-chain transfer simulation. Nothing settles, so no money moves. You get back whether a real payment would be accepted, and if not, the facilitator own reason verbatim. Pass ?url= or ?domain=.
