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.

Regulatory Posture applies to this provider. Its tags matched the Securities & Market Data regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/databento: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
