Query the chain · Blockchain API

Bitcoin blockchain API for the entire indexed chain

The Bitcoin blockchain API gives you the entire chain through one interface. Every block since the 2009 genesis block is parsed and reconciled, so you can read any block, expand any transaction to its inputs and outputs, look up any address and balance to the satoshi, inspect UTXOs and script types, and follow flows, without running Bitcoin Core or building an indexer.

It is built for apps, wallets, explorers and analytics that need the full blockchain on demand. The same data is queryable three ways, REST, SQL and dashboards, and stays reconciled block by block. Usage-based pricing, no node to run. Informational data only, not advice.

Why it works

What you get with blockchain api

The whole chain, on demand

Blocks, transactions, addresses, balances, UTXOs, labels and flows are all reachable through one API, from the genesis block to the current tip.

Indexed and reconciled

Each block is parsed and balanced as it confirms, so the blockchain data you read is consistent and current without you running a node.

Three ways to access

The same indexed blockchain is available via REST, SQL and dashboards, so apps, analysts and operators each use the interface 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.

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 blockchain api

The entire chain since the 2009 genesis block: blocks, transactions, inputs, outputs, addresses, balances, UTXOs, script types, entity labels and flows, all indexed and reconciled. You reach it via REST, SQL or dashboards.

Yes. New blocks are parsed and reconciled as they confirm, and unconfirmed activity is visible in the mempool. It provides informational on-chain data and is not financial or investment advice.
