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 parsed bitcoin_block_header string, an evidence_scope indicating the data came from caller-supplied input, a list of validation warnings (if any), and a full service receipt including payment details, request/execution IDs, result hash, latency, and settlement reference.
Example use cases
Debug malformed Bitcoin block header
“I have this raw Bitcoin block header and I think something might be wrong with it — can you inspect it and flag any warnings: 0200000035ab154183570f7264b738941a42d4a8dc9f14f7ae1f3d8498cd40000000000038b2ef4175a0c675e5a11da49d4d4ed9ee57b4c5494e1c87d04013a0ad9a2af0ae4da159ffff001d00000000?”
Verify Bitcoin block header structure for audit
“For our compliance audit, I need to verify the structure and validity of this Bitcoin block header — please parse it and tell me all the fields and any issues found: 01000000e76dd7e2f68498a1bcc65fa0b8a9b58bbb31d4fac1bc87a80000000000000000e7e9e2e8c7a6d21cd9d1e1e1e1e1e1e1e1e1e1e1e1e1e1e1e1e1e1e1e1e1e1e1e1ffff001d?”
Extract timestamp from historical Bitcoin block header
“Can you inspect this Bitcoin block header from a historical block and extract the timestamp and difficulty target from it: 0100000081cd02ab7e569e8bcd9317e2fe99f2de44d49ab2b8851ba4a308000000000000e320b6c2fffc8d750423db8b1eb942ae710e951ed797f7affc8892b0f1fc122bc8c874ffff001d?”
Technical details
Endpoint
POSThttps://signalharness.ai/api/agent/services/bitcoin_block_header_inspect/invokeWhen to prefer
Choose this endpoint when you need to programmatically parse and inspect a raw Bitcoin block header string (e.g. hex-encoded) to extract its fields or identify structural warnings. Prefer it over general blockchain explorers when you already have raw header bytes and need structured extraction via API, or when operating in an agent-native x402 payment context at very low cost ($0.01 USDC).
Side effects
- Invalid or malformed header string causes parse failure and non-succeeded status
- Header string too short or too long (outside 2–65536 character bounds) triggers schema validation error
- Malformed JSON request body returns 400-level error
- Payment failure via x402 protocol returns 402 Payment Required
- Network or infrastructure errors may return 5xx responses
