How this service works
Bitcoin transaction analysis: classify any BTC tx's money-movement ROLE (consolidation / fan-out / payment) and place it in Bitcoin's value-homophily law — what KIND of flow is this, is it whale-tier, does it move among its own kind? Unique PLEXUS money-graph analysis (base-rate-corrected role assortativity), not raw RPC. For Bitcoin forensics, flow classification, whale tracking ... Cryptographically signed (Ed25519) — every response is independently verifiable via /.well-known/obol-pubkey.
Output
Returns the money-movement role label (consolidation / fan-out / payment), a PLEXUS base-rate-corrected role assortativity score reflecting Bitcoin's value-homophily law, a whale-tier flag, and metadata indicating whether the transaction moves value among peers of similar kind in the on-chain money graph.
Example use cases
Example prompt
“Can you classify what role this Bitcoin transaction plays — is it a consolidation, fan-out, or payment — and tell me if it looks whale-tier based on value-homophily? The txid is 1ba9000f5eb10e8fa1a2dbf6125cc1b0d4740f8f8b114b7a91229056ac2e1b9d.”

Choose this endpoint when you need semantic classification of a Bitcoin transaction's structural role in the money graph — not just raw RPC data. Ideal for Bitcoin forensics agents, compliance tools, whale trackers, and exchange consolidation detectors that need PLEXUS assortativity scoring and value-homophily context rather than simple input/output address counts.
Side effects
- Transaction ID not found on Bitcoin mainnet — returns 404 or error body
- Malformed txid (wrong length or non-hex) — returns 400 validation error
- Payment required / 402 if x402 micropayment header is missing or insufficient
- Transaction too recent and not yet confirmed — may return incomplete analysis
- Rate limiting or upstream node unavailability — 5xx response
