Query the chain · Node API

Bitcoin node API and RPC access without running a full node

A Bitcoin node API gives you the data a full node holds without the cost of running one. Bitcoin Core needs hundreds of gigabytes of disk, days to sync from the genesis block, and constant reconciliation as new blocks confirm. BitcoinDatabase keeps that node indexed for you and exposes the same information over a clean REST endpoint: fetch a block by height or hash, pull a raw transaction, read an address balance to the satoshi, and check the mempool.

If you already speak JSON-RPC, the mapping is direct. Calls like getblock, getrawtransaction, getblockcount and getmempoolinfo map to REST endpoints that return typed JSON, so you can retire your own node or run us as a redundant backend. 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 node api

A node without the node

We run and reconcile Bitcoin Core for you, so you skip the disk, the multi-day initial sync and the DevOps of keeping a full node at the chain tip.

JSON-RPC calls you know

getblock, getrawtransaction, getblockcount and getmempoolinfo map to REST endpoints that return clean, typed JSON, so porting existing node code is mostly a URL change.

Same data, three ways

The indexed chain behind the node API is also queryable in SQL and dashboards, so analysts and apps read from one authoritative dataset.

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.

Fetch any block by height or hash with full transactions
Pull raw and decoded transactions with inputs and outputs
Read address balances and history to the satoshi
Check mempool size, fees and unconfirmed transactions
Replace or back up your own node with one API key

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 node api

It is a fully-indexed copy of the chain served over a REST API. We run and reconcile the node infrastructure so you do not have to, then expose blocks, transactions, balances and mempool state through endpoints that return typed JSON. You get node-grade data without syncing Bitcoin Core yourself.

For read queries, yes. Common calls like getblock, getrawtransaction, getblockcount and getmempoolinfo have direct REST equivalents that return the same fields. Broadcasting your own transactions still needs your own node or wallet. This is informational on-chain data, not financial advice.
