Databento

Years of integrating hundreds of trading venues convinced a group of former trading-firm engineers that getting a new dataset into production costs far too much effort, and Databento was started to fix that. The company supplies licensed market data through APIs, flat files and private connections, and it was built around a simple idea that customers should pay only for the data they use. It says its users range from pre-product startups to investment firms with billions under management.

Data in the shape the work needs

Its catalogue is grouped by how the data is delivered. Normalized data comes as live streaming feeds covering real-time and intraday needs, and as historical data downloadable over API and flat files. Reference data covers corporate actions, such as company events and adjustments, and a security master with identifiers and mappings. Raw data is offered as lossless packet captures, and dedicated connectivity provides private links for better uptime and latency. Supported asset classes are options, futures, equities and indices, and developer material includes API references, a quickstart, tutorials and GitHub examples.
