Query the chain · Address lookup

Bitcoin address lookup with balance, history and UTXOs

A Bitcoin address lookup should return more than a number. Point BitcoinDatabase at any address and get its current balance to the satoshi, total received and sent, every transaction it has touched since the 2009 genesis block, its unspent outputs (UTXOs), and any entity label we have for it such as an exchange, miner or service.

Do it in the API for an app, in SQL for an analysis, or in a dashboard for a quick check. The chain is fully indexed, so even high-activity addresses return instantly. Informational on-chain data only, never advice or claims about a person's identity.

Why it works

What you get with address lookup

Balance to the satoshi

Get the exact current balance, total received and total sent for any address, computed from every confirmed input and output on the indexed chain.

Full history and UTXOs

See every transaction the address has ever touched and its current unspent outputs, so you can reconstruct activity from first principles.

Entity labels when known

Where an address clusters to a known exchange, miner or service, we attach a label as informational context, not an accusation or identity claim.

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 lookup

The current balance to the satoshi, total received and sent, full transaction history, current UTXOs, and any entity label such as exchange or miner. Everything is computed from the fully-indexed chain, so even busy addresses respond fast.

No. Labels are informational context from on-chain clustering, such as an address belonging to a known exchange wallet. They are not identity claims about individuals, and this is data only, not legal or financial advice.
