How this service works
Explore 330 pay-per-call x402 API services and 27 agent-native digital products, with Base USDC pricing, secure Polar checkout, and free discovery.
Output
Returns a JSON object with a 'status' field ('succeeded' or otherwise), a 'result' object containing the 'bitcoin_merkle_verification' outcome, any 'warnings', and an 'evidence_scope' indicating that the verification is based on caller-supplied data. Also includes a 'receipt' with payment details, request/execution IDs, and a SHA-256 hash of the result for auditability.
Example use cases
SPV payment confirmation for e-commerce
“I received a Bitcoin payment and the buyer sent me a Merkle proof showing the transaction is in block 850000. Can you verify this Merkle proof to confirm the transaction is genuinely included in the Bitcoin blockchain? Here's the proof JSON: {proof_data}.”
Auditing Bitcoin transaction inclusion for compliance
“We need to audit whether a specific Bitcoin transaction was actually included in the blockchain for our compliance records. Here's the Merkle proof data — please verify it and tell me if the inclusion is confirmed or if there are any warnings.”
Trustless Bitcoin payment verification in a smart contract workflow
“Before releasing escrow funds, I need to verify a Bitcoin Merkle proof that proves a BTC payment was confirmed on-chain. Can you run the Merkle proof verification on this data and return the result so I can proceed?”
Technical details
Endpoint
POSThttps://signalharness.ai/api/agent/services/bitcoin_merkle_proof_verify/invokeWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-use cryptographic verification of Bitcoin Merkle proofs without running a full Bitcoin node. It is ideal for agents handling SPV (Simplified Payment Verification) scenarios, e-commerce payment confirmation, compliance auditing of BTC transactions, or any workflow where trustless Bitcoin inclusion proof validation is required for a low cost ($0.01 USDC per call).
Side effects
- Malformed or invalid Merkle proof input causes verification failure
- Proof data exceeds the 65536 character limit and is rejected
- Caller-supplied data does not correspond to a real Bitcoin block or transaction, resulting in a failed verification with warnings
- Payment not processed (x402 flow not completed), blocking invocation
- Network or service unavailability returns a non-success status
