aid: databento url: https://raw.githubusercontent.com/api-evangelist/databento/refs/heads/main/apis.yml name: Databento kind: company description: 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. image: https://kinlane-images.s3.amazonaws.com/shared/apis-json/apis-json-logo.jpg tags: - Market Data - Financial Data - Reference Data - Historical Market Data - Trading created: '2026-07-11' modified: '2026-07-11' specificationVersion: '0.19' apis: - aid: databento:databento-historical-timeseries-api name: Databento Historical Timeseries API tags: - Historical Market Data - Market Data - Timeseries - Trading - Financial Data image: https://kinlane-images.s3.amazonaws.com/shared/apis-json/apis-json-logo.jpg humanURL: https://databento.com/docs/api-reference-historical/timeseries/timeseries-get-range baseURL: https://hist.databento.com/v0 properties: - url: https://databento.com/docs/api-reference-historical type: Documentation - url: https://databento.com/docs/api-reference-historical/timeseries/timeseries-get-range type: APIReference - url: openapi/databento-openapi.yml type: OpenAPI - url: collections/databento.postman_collection.json type: PostmanCollection - url: collections/databento.opencollection.json type: OpenCollection description: Streams historical market data over HTTP for a requested date/time range. A single request selects a dataset, one or more symbols, a schema (MBO full order book, MBP-1/MBP-10, trades, OHLCV bars, statistics, and more), and a time range, and returns normalized records in DBN, CSV, or JSON. Billed per byte streamed.
