Find out what an x402 endpoint will charge before you pay it.

Find out what an x402 endpoint will charge before you pay it. Probes the endpoint, reads the challenge from the header or the body, and returns the decoded price, network, asset and payTo plus the declared input and output schemas. Never sends a payment. Only reviewed origins are reachable, and a redirect is refused rather than followed.
