uxc_verify_payment
BUYER-SIDE. After paying a resource (from uxc_view_door) on-chain from your own wallet, submit the transaction hash to settle it. Pass the challengeId from the accepts[] entry you paid and the on-chain transaction hash. Returns settled (confirmed) or pending (awaiting confirmations). No seller key needed - the challengeId identifies the resource, and settlement is gated by on-chain confirmation.

No key. Use as a BUYER to see what to pay, then uxc_verify_payment after paying. status=true polls settlement without minting a new challenge.

{'type': 'object', 'required': ['res_id'], 'properties': {'res_id': {'type': 'string'}, 'status': {'type': 'boolean', 'description': 'poll mode: GET /r/{id}?status=1 - no-mint settlement check'}}}
