What is it?

OpenBB's Open Data Platform (ODP) is an open-source toolset for data engineers who need to integrate proprietary, licensed and public data sources into downstream applications such as AI copilots and research dashboards. It follows a connect-once, consume-everywhere model: data is wired in one place and then served to several front ends at the same time.

The main entry point is the Python package, installed with pip install openbb. Users call functions such as obb.equity.price.historical("AAPL") and convert the result to a pandas DataFrame. The package also ships an openbb-api command that starts a local FastAPI server, which can be connected to the OpenBB Workspace UI as a data backend. A separate openbb-cli package provides a command-line interface.

The platform covers equities, derivatives, fixed income, crypto and economic data, with the provider list documented in the project's reference pages. Data is exposed through Python, Excel, MCP servers for AI agents and REST APIs.
