CoinAPI alternative for on-chain Bitcoin data

CoinAPI is a broad, well-regarded market data provider: prices, order books, OHLCV and trades aggregated across hundreds of exchanges and thousands of assets, over REST, WebSocket and FIX. If you need cross-asset market and price data in one feed, it is a strong tool and does that job well.

The reason a team looks for a CoinAPI alternative is usually that they need on-chain data, not market data. CoinAPI tells you what bitcoin traded for; it does not hand you an address balance to the satoshi, a full UTXO set, a transaction's inputs and outputs, or entity labels and fund flows. BitcoinDatabase is Bitcoin-native on-chain infrastructure: the fully-indexed chain over a REST API, SQL and dashboards on usage-based paid plans. The two are often complementary, CoinAPI for prices and BitcoinDatabase for the chain itself, but if the on-chain layer is what you are missing, that is the gap this fills. Informational on-chain data only, not financial advice.
