Requires API keys from multiple data providers (stock/crypto/options sources) to access real data.

Use freely for any purpose, but you must share modifications under the same AGPLv3 license and provide source code access to users.

In plain English

OpenBB is an open-source financial data platform that acts as a unified access layer for financial market data. The problem it solves is fragmentation: financial analysts, quantitative researchers, and developers working with market data typically need to connect to many different data providers, stock price feeds, economic data, cryptocurrency exchanges, options data, fixed income data, each with their own API format, authentication scheme, and data structure. OpenBB provides a single Python interface that normalizes all of this into a consistent format. The way it works is through an Open Data Platform architecture: you install the Python package, connect it to your preferred data providers (both free public sources and licensed commercial ones), and then query all of them through a consistent API. For example, fetching historical stock prices for Apple looks the same whether the data comes from one provider or another. The results can be returned as pandas DataFrames, making them immediately usable in analysis workflows. The platform can also expose all of this data as a REST API, enabling other applications, including AI agents via Model Context Protocol servers, to consume it. Beyond the Python library, OpenBB offers a commercial web workspace (OpenBB Workspace) that provides a graphical dashboard interface and supports AI agents for research tasks. You would use OpenBB if you are a quantitative analyst or data engineer building a financial research workflow, a developer building a trading application that needs clean normalized market data, or a researcher wanting to explore financial data across equities, derivatives, crypto, fixed income, and macroeconomics from a single tool. The library requires Python 3.9 to 3.12 and is installed via pip. It is licensed under AGPLv3.

Copy-paste prompts
