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 23 APIs on the APIs.io network, including Historical Timeseries API, Metadata API, Symbology API, and 20 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.
Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it
carries 10 points of the composite. It is scored from the published contracts
themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already
holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in
front of it, and the first time that check is skipped a duplicate record is created.
Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet,
not penalised by it.
The six quality facets above are damped to 75 points between them,
because the conditional facet above carries the other
25. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 75% 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/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. 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.
