POST /cryptovar/x402/proof_verify
unprobed
Check a SHA-256 against a Securaw/TimeChain2 event. Reports registry checks and direct-file Bitcoin proof separately, with downloadable proof when available. Missing events and mismatches are billable results. Pending/unavailable is NOT Bitcoin confirmed. Legacy receipts without direct-file proofs are explicitly identified. No arbitrary-chain verification. Idempotency-Key required.
Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
