`check_payment`Inspect a public HTTPS URL for a fresh x402 v2 HTTP 402 challenge using an unsigned GET with a 10-second network timeout and no redirect following. Returns validated payTo, asset, network, atomic amount, resource and maxTimeoutSeconds; incomplete or non-x402 responses return challenge=null and a reason. Does not sign, settle or verify receipts. Fresh requirements override documented receiver hints; inspect canonical_receiver_match before choosing to pay.
