x402 payment integration check
Written by Agorean from what the endpoint says about itself
Confirms your x402 payment integration works and tells you which networks are available.
It is a payment integration check with no external data lookup. It returns the time, the payment rail, the network mode, and which capabilities are free versus paid. The challenge lists which networks, such as Base, Polygon, Arbitrum, or XDC, are currently available for payment, and the receipt identifies the network and transaction actually used. It is restricted to business or professional use.
WHEN TO USE THIS

For example: Send the check and read the returned receipt.
When: I need to know which payment networks are currently accepted
For example: Read the network list in the returned challenge.
When: I need to see which capabilities are free versus paid before building against a service
