OpenBB

Project Overview

OpenBB (Open Data Platform, ODP) is an open-source financial data integration platform that helps data engineers unify proprietary, licensed, and public data sources and serve them to downstream consumers: quant research environments, analyst dashboards, AI agents (via MCP servers), and REST APIs. Its core idea is connect once, consume everywhere: data is integrated once, then shared across Python environments, Excel, OpenBB Workspace, and AI agents. Coverage spans equities, options, fixed income, crypto, and economic data.

A unified access layer for financial data: integrate once, consume everywhere.

Key Features

• Unified Python interface: fetch historical prices with one call — obb.equity.price.historical('AAPL') — and convert results to a DataFrame
• Multi-source aggregation: proprietary, licensed, and public sources behind a single interface
• REST API service: the openbb-api command launches a local FastAPI server exposing all data endpoints
• MCP server: an MCP endpoint for AI agents to query financial data directly
• OpenBB Workspace integration: connect the backend to the enterprise analytics UI in a few clicks
• CLI access: install openbb-cli to query data from the command line
• Multi-asset coverage: equities, options, fixed income, crypto, and economic data

Target Audience

• Quant researchers and data engineers
• Financial analysts and research teams
• Developers building financial AI agents
• Fintech teams aggregating multiple data sources

Quick Start

1. Install: pip install openbb
2. Query data:

from openbb import obb

output = obb.equity.price.historical('AAPL')
df = output.to_dataframe()

3. Start the local API server: run openbb-api and verify at http://127.0.0.1:6900
4. Connect to OpenBB Workspace: add the backend URL from the Workspace Apps page

Core Advantages

• Integrate once, use everywhere: Python, REST, MCP, and Excel share one data layer
• Open-source foundation: the platform core is open, with extensibility for custom sources
• AI-ready: designed for AI agents natively, with MCP support out of the box

System Requirements

Notes

• Source credentials: default endpoints rely on free sources; proprietary vendors need their API keys configured in the platform
• Investment risk: the project states financial data is for reference only; trading decisions carry your own risk
