Query the chain · Bitcoin API

Bitcoin API for the fully-indexed blockchain

A Bitcoin API should hand you the on-chain truth without making you run a node or build your own indexer. BitcoinDatabase parses every block since the 2009 genesis block and exposes it as a clean REST API: look up any address balance to the satoshi, pull a transaction with its inputs and outputs, check confirmations, or page through a block, all in a single call.

The same indexed data is queryable three ways, REST for your app, SQL for your analysts, and dashboards for everyone else. Start with an API key in minutes and pay for what you query. This is informational on-chain data only, not financial or investment advice.

Why it works

What you get with bitcoin api

Every block indexed

Each block from the 2009 genesis block forward is parsed and reconciled, so addresses, transactions, balances and UTXOs are queryable the moment you call the API.

No node required

Skip running Bitcoin Core and building an indexer. One API key gives you balances to the satoshi, transaction detail, confirmations and block data straight away.

Three ways to query

The same data is exposed as REST for apps, SQL for analysts and dashboards for everyone else, so each team queries the chain the way that fits.

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.

Look up any address balance to the satoshi
Fetch transactions with full inputs and outputs
Read blocks, confirmations and mempool state
Page through full address transaction history
Query the same data via REST, SQL or dashboards

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 bitcoin api

Addresses and their balances to the satoshi, transactions with every input and output, blocks, confirmations, UTXOs, entity labels and historical market data. Every block since the 2009 genesis block is indexed, so lookups are instant and you never run a node.

No. BitcoinDatabase has already indexed and reconciled the chain block by block. You call a REST endpoint, run SQL, or open a dashboard. This is informational on-chain data only and not financial or investment advice.
