Coverage

Millions of public labels across the Bitcoin ecosystem — sourced from research datasets, curated anchors, and heuristic clustering. Every label carries its confidence tier, evidence tier, and caveats; most leads are inferred, not verified.

Capabilities

Three capabilities, one API. Every response includes a confidence tier, an evidence tier, and structured caveats.

Chain Intelligence

Identify any address — entity, category, confidence, evidence tier. Batch up to 100 at once.

Transaction Verification

Confirm payments hit the right address and amount. Look up any txid for inputs, outputs, and fees.

Timestamping

Anchor any hash to the Bitcoin blockchain. Download cryptographic proofs. Verify existing timestamps.

Endpoints

Public beta: the full API surface is free right now. Billing stays wired for the post-beta access model.
