Query the chain · Block explorer API

Bitcoin block explorer API for blocks, transactions and addresses

Building a block explorer means indexing every block, transaction, input and output and keeping it reconciled as new blocks arrive. The Bitcoin block explorer API gives you that index ready-made: query a block by height or hash, expand any transaction down to its scripts and outputs, look up an address with its full history and confirmations, and read live mempool state.

Your explorer or wallet UI calls clean REST endpoints while we keep the chain indexed and reconciled block by block. The same data is also available in SQL and dashboards. Informational on-chain data only, not investment advice.

Why it works

What you get with block explorer api

Blocks to outputs

Query any block by height or hash and drill into transactions, inputs, outputs, script types and confirmations, all from one indexed source.

Reconciled block by block

We parse and reconcile each new block as it confirms, so your explorer always reflects the current tip without you running Bitcoin Core.

Address and mempool views

Look up an address with its balance and full transaction history, and read live mempool entries, exactly what an explorer needs to render.

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 block explorer api

Yes. It returns blocks, transactions, inputs, outputs, script types, addresses, balances, confirmations and mempool entries, which is everything an explorer renders. We keep the chain indexed and reconciled, so you focus on the UI.

Each block is parsed and reconciled as it confirms, and unconfirmed activity is available through the mempool endpoints. The same indexed data is also queryable via SQL and dashboards.
