How do I query the Bitcoin blockchain?

You query the fully-indexed Bitcoin blockchain three ways: a REST API for addresses, transactions, balances, blocks and UTXOs, raw SQL from the Growth plan for your own research, and ready-made dashboards. Every block since the 2009 genesis is indexed and reconciled against the canonical chain, so a lookup is one request and you never run a node. This is informational on-chain data only, not financial advice.

Do I need to run a Bitcoin node?

No. BitcoinDatabase indexes the whole chain for you and keeps it current within seconds of each new block, so address, transaction, balance, block and UTXO queries are simple REST calls or SQL. There is no node, indexer or ETL pipeline to operate.

Addresses and balances to the satoshi, transactions with inputs, outputs and confirmations, blocks, UTXOs and scripts, mempool activity, entity labels and fund flows, plus on-chain metrics like active addresses, realized cap, SOPR, HODL waves, exchange flows and the rich list.

How it works

How to query the Bitcoin blockchain

Three steps, no node to run. Pick how you want to query the fully-indexed chain, then look up an address, transaction, balance, UTXO or on-chain metric, and ship it into your app, your analysis or your monitoring. Informational on-chain data only, not financial advice.

The flow

From a question to an answer in three steps

The chain is already indexed and reconciled block by block. Here is exactly what happens from the moment you decide what to query to the moment the data lands in your stack.

Pick access → Query Bitcoin → Ship it

01 / PICK YOUR ACCESS

Choose how you query

Three ways into the same indexed chain. Grab an API key for the REST API, write raw SQL against the data from the Growth plan, or open a ready-made dashboard. Use one or mix all three.

02 / QUERY BITCOIN

Ask for what you need

Look up an address balance to the satoshi, resolve a transaction with its inputs, outputs and confirmations, list UTXOs, page through blocks since the 2009 genesis, or pull an on-chain metric series.

03 / SHIP IT

Put the data to work

Wire results into apps and wallets, run reproducible research and dashboards, or stand up address and flow monitoring with webhooks. New blocks land within seconds, so what you ship stays current.

One call

A balance lookup in a single request

You do not sync a node, build an indexer or stitch together an ETL pipeline. One GET to the API returns the address, its balance to the satoshi and its activity, typed and ready to use.

Query by address, transaction hash, block height or metric
Indexing, reconciliation and node operations are fully managed
Balances to the satoshi, with confirmations and full history
Switch to raw SQL from the Growth plan for your own research
Informational on-chain data only, not financial or legal advice

GET /v1/address/{addr} 200 OK

# one call returns the address and its balance
curl https://api.bitcoindatabase.com/v1/address/bc1q...x7 \
