Example use cases
Pre-signing PSBT safety review
“Before I sign this PSBT, can you decode it and tell me what inputs, outputs, and fees are involved, and flag anything that looks off? PSBT: cHNidP8BAHECAAAAAe2poetn...”
Wallet integration PSBT audit
“I'm building a wallet and need to show users what a PSBT contains before they approve it — can you analyze this base64-encoded PSBT and return the decoded transaction details and any warnings? Here it is: cHNidP8BAFICAAAAAQ==”
Multi-sig transaction inspection
“Our multisig coordinator just sent me a PSBT to co-sign. Can you inspect it and tell me if anything looks suspicious or unexpected before I add my signature? PSBT data: cHNidP8BAFUCAAAAASeaIyM...”
Technical details
Endpoint
POSThttps://signalharness.ai/api/agent/services/bitcoin_psbt_inspect/invokeWhen to prefer
Choose this endpoint when you need a quick, agent-native, micropayment-gated PSBT inspection without spinning up a local Bitcoin node or library. Ideal for AI agents that need to analyze user-supplied PSBTs on-the-fly at $0.015 per call, especially when building autonomous Bitcoin transaction review workflows or wallet UIs that need serverless PSBT decoding.
Side effects
- Invalid or malformed PSBT string returns an error or empty inspection
- PSBT exceeds 65536 character max length — request rejected
- Malformed base64 encoding causes parse failure
- Payment not completed results in 402 response before execution
- Network or service unavailability returns a non-200 status
