Query the chain · Address balance API

BTC address balance API with exact balances and UTXOs

The BTC address balance API answers the most common question first: what is the exact balance of this address? Pass one address or a batch and get the current balance to the satoshi, total received, total sent, and the list of unspent outputs (UTXOs) backing the balance, all from the fully-indexed chain.

Use it to power a wallet, audit holdings, or reconcile cold storage across many addresses in one batched call. It is fast because the chain is already indexed and reconciled, so you skip running a node entirely. Query it as REST, in SQL, or on a dashboard. Informational data only, not advice.

Why it works

What you get with address balance api

Exact balance, fast

Return the precise balance to the satoshi plus total received and sent for any address, computed from every confirmed input and output.

UTXOs included

Get the list of unspent outputs backing a balance, so you can build spends, estimate fees and audit holdings down to each coin.

Single or batched

Check one address or many in a single batched call, ideal for wallets and cold-storage reconciliation across large address sets.

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 balance api

Yes. The balance API accepts batched addresses and returns the exact balance, received, sent and UTXOs for each, which is ideal for wallets and reconciling cold storage across large address sets.

Confirmed balances come from the reconciled chain, and pending activity is visible through the mempool. Everything is computed from the fully-indexed chain, so no node is needed. It is data only, not financial advice.
