Bitcoin address screening API for risk scores and sanctions exposure

Screening a Bitcoin address means checking, before you onboard a wallet or clear a transaction, whether it matches a sanctions list or has moved coins to and from entities your team treats as high risk. The Bitcoin address screening API answers that from the fully-indexed chain: BitcoinDatabase matches the address against published sanctions designations, then traces its direct and near counterparties across labeled exchanges, mixers, and services to surface exposure, and returns a risk signal your compliance team can act on.

Call it over REST at onboarding and per transaction, or run SQL to rescreen a whole book of addresses when a list updates. Every score traces back to the labeled transactions behind it, so an analyst can open the evidence rather than trust a number. This is informational on-chain data and compliance tooling: it surfaces matches and exposure as signals to support your team's own review and decisions. It is not an accusation, a legal determination, or a claim about any individual, and it is not legal advice.

Why it works

What you get with address screening

Sanctions-list matching

Check an address against published sanctions designations at onboarding and before you clear a transaction, the two points where screening matters most, and rescreen your whole book automatically when a list changes.

Exposure, not just direct hits

A clean address can still receive coins one hop from a sanctioned or high-risk cluster. The API traces direct and near counterparties across labeled exchanges, mixers and services so indirect exposure surfaces, not only exact matches.

Evidence your analyst can open

Every risk signal traces back to the labeled transactions that produced it. Because labels and raw transactions share one schema, an analyst can drill from the score to the exact flows and document the review.

What it handles

The indexed Bitcoin chain, queryable your way

Look up an address, a transaction, a UTXO, the rich list or an on-chain metric, by REST API, SQL or dashboard. The same authoritative data, reconciled block-by-block against the canonical chain, without running a node.

Why BitcoinDatabase

One platform, queryable three ways

Not a raw node to sync, not an indexer to build, and not five vendors to stitch together. The fully-indexed Bitcoin blockchain, available as a REST API, as SQL, and as dashboards, on one authoritative dataset.

REST API

Typed JSON for addresses, transactions, balances, UTXOs and metrics. Drop it into apps, wallets, explorers and agents with curl, Python or our SDKs.

SQL access

Run SQL directly against the indexed Bitcoin dataset for ad-hoc analysis, cohorts and exports, the same data the API and dashboards read from.

Compliance-first

Informational on-chain data and analytics only. Entity labels and flow tracing are framed as tooling to support a regulated team's own review, not accusations.

Good questions

Questions about address screening

Screening checks an address against published sanctions lists, then traces its counterparties across labeled exchanges, mixers and services to measure exposure to high-risk entities, returning a risk signal. BitcoinDatabase computes this from the fully-indexed chain and traces every signal back to the underlying transactions.

No. A risk signal describes on-chain exposure and list matches as context for a compliance team's own review. BitcoinDatabase provides informational data and analytics only, not an accusation, a legal determination, or a claim about any individual, and not legal advice.
