Databento

Databento is a market data platform that delivers historical and live financial market data through a single, normalized API. It covers equities, futures, options, and other asset classes across major venues, with full order book depth (MBO/MBP), trades, OHLCV bars, and reference data. Historical data is served over a REST HTTP API (hist.databento.com) with pay-as-you-go billing per byte streamed, while live data is delivered over a low-latency raw TCP binary protocol using Databento Binary Encoding (DBN). Official Python, C++, and Rust client libraries wrap both surfaces, and a Reference API provides security master, corporate actions, and adjustment factor data.

Databento publishes 6 APIs on the APIs.io network, including Historical Timeseries API, Metadata API, Symbology API, and 3 more. Tagged areas include Market Data, Financial Data, Reference Data, Historical Market Data, and Trading.

Databento’s developer surface includes changelog, CLI, pricing, support, signup flow, getting-started guide, API reference, and 32 more developer resources.
