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 decoded Bitcoin transaction details, any warnings about the transaction, the service ID, evidence scope, and a full payment receipt with execution metadata including latency, payment ID, receipt ID, and a SHA-256 hash of the result for integrity verification.
Example use cases
Pre-broadcast transaction inspection
“Before I broadcast this raw Bitcoin transaction, can you decode it and tell me exactly what inputs and outputs it has? Here's the hex: 02000000000101abc123...”
Auditing a suspicious transaction
“I have this serialized Bitcoin transaction from an unknown source — decode it for me so I can audit what it's actually doing: 01000000017f4e...”
Wallet developer debugging
“I'm building a Bitcoin wallet and need to verify my transaction serialization is correct. Can you decode this raw tx and show me the parsed fields: 010000000001...?”
Technical details
Endpoint
POSThttps://signalharness.ai/api/agent/services/bitcoin_transaction_decode/invokeWhen to prefer
Choose this endpoint when you need a quick, pay-per-call Bitcoin transaction decoder without setting up your own node or library. It is ideal for agents that occasionally need to inspect raw transaction data, audit third-party transactions, or debug serialized Bitcoin transactions, especially in environments where installing Bitcoin libraries is impractical.
Side effects
- Invalid or malformed transaction hex returns a decode error
- Transaction string too short (< 2 chars) fails input validation
- Transaction string exceeding 65536 characters is rejected
- Non-Bitcoin transaction formats (e.g. Ethereum RLP) may produce warnings or fail
- Payment failure via x402 protocol results in 402 response before execution
