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 containing the classification label for the Bitcoin script (e.g. P2PKH, P2SH, P2WPKH, P2WSH, P2TR, non-standard), a list of any warnings about the script, an evidence scope indicator ('caller_supplied_data'), and a full execution receipt including payment details, latency, and a SHA-256 result hash for auditability.
Example use cases
Identify unknown transaction script type
“I pulled this raw Bitcoin locking script from a transaction and I'm not sure what type it is — can you classify it for me? Here's the hex: '0014{witnessProgram}'.”
Audit Bitcoin wallet output scripts
“I'm reviewing a batch of Bitcoin outputs and need to check what script type this one uses and whether there are any warnings I should know about: '76a914{pubKeyHash}88ac'.”
Verify Taproot script before broadcast
“Before I broadcast this transaction, can you classify this Bitcoin script and tell me if there are any warnings? The script is: '5120{taprootWitnessProgram}'.”
Technical details
Endpoint
POSThttps://signalharness.ai/api/agent/services/bitcoin_script_classify/invokeWhen to prefer
Choose this endpoint when you need programmatic, agent-friendly classification of raw Bitcoin scripts as part of a blockchain analysis, wallet auditing, or transaction inspection workflow. It is purpose-built for AI agents with per-call micropayment pricing via x402/USDC, making it ideal for on-demand script analysis without a subscription. Prefer it over general-purpose blockchain explorers when you need structured, machine-readable output with receipts and auditability.
Side effects
- Invalid or malformed script input returns an error or unclassified result
- Script too short (below minLength of 2 characters) rejected at input validation
- Script exceeding 65536 characters rejected at input validation
- Network or payment settlement failures captured in receipt status field
- Unknown or non-standard scripts may return a generic classification with warnings
