x402
Securaw TimeChain2 SHA-256 Bitcoin Proof Verification is a paid API for AI agents from www.securaw.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-18).
Verifies a SHA-256 hash against a Securaw/TimeChain2 event, reporting both registry checks and direct-file Bitcoin timestamp proof separately with downloadable proof when available.

How this service works
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.
Output
Returns a structured result distinguishing registry-level checks from direct-file Bitcoin proof confirmation, indicates whether a proof is downloadable, flags mismatches between the provided SHA-256 and the event record, explicitly identifies legacy receipts lacking direct-file proofs, and clarifies that pending or unavailable statuses are not Bitcoin-confirmed. Missing events and mismatches are billable results.
Example use cases
Audit trail for legal document
“I need to verify that our signed contract — SHA-256 hash b94d27b9934d3e08a52e52d7da7dabfac484efe04294e576b4b0d02e9bf1aab7 — is genuinely timestamped on the Bitcoin blockchain under Securaw event ID LEGAL-CONTRACT-2024-Q3. Can you check and download the proof if it's available?”
Intellectual property timestamp check
“We submitted a design file to TimeChain2 last quarter and got a receipt. Can you confirm that the file with SHA-256 5f4dcc3b5aa765d61d8327deb882cf994b07ea3a3932b6c0e3b9b1e8b06f1239 is genuinely Bitcoin-confirmed under event ID IP-DESIGN-REV2?”
Financial record integrity verification
“Before we close the audit, can you verify that our Q4 financial report with hash e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855 actually has a direct-file Bitcoin proof attached to event ID FINRPT-Q4-2024, not just a registry entry?”
Technical details
Endpoint
POSThttps://www.securaw.com/cryptovar/x402/proof_verify?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to cryptographically verify that a specific file's SHA-256 hash is anchored to the Bitcoin blockchain via a Securaw/TimeChain2 event, particularly when you need the distinction between a registry-level check and a direct-file Bitcoin proof, or when you need to download a proof artifact. Not suitable for verifying timestamps on arbitrary blockchains, general hash lookup without a TimeChain2 event ID, or non-Bitcoin proof systems.
Side effects
- Event ID not found — billable result returned indicating missing event
- SHA-256 mismatch between supplied hash and event record — billable mismatch result
- Proof status is pending or unavailable — not Bitcoin confirmed, clearly flagged
- Legacy receipt without direct-file proof — identified explicitly in response
- Invalid SHA-256 format (not 64 lowercase hex chars) — validation error
- Invalid event_id format — validation error
- Missing Idempotency-Key header — request rejected
- Payment failure or insufficient USDC balance — 402 payment required
