openbb-core
OpenBB package with core functionality.
Decision gist · record as of 2026-08-14
Yes, if you are building an OpenBB Platform extension or data consolidation layer and can comply with AGPL-3.0 copyleft terms. No, if you need a standalone data library or cannot open-source derivative works. The package is actively maintained, has low install friction, and provides well-structured infrastructure for multi-surface data integration—but it is not a general-purpose library and requires significant extension work to be useful.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python >=3.10,<3.14.
- Intended as a project dependency for building extensions, not as a standalone package; you will need to extend its classes and integrate it into a larger OpenBB Platform application.
- Low friction installation via pip; active maintenance with a release within the last 58 days.

What it is and what it does
openbb-core is the foundational infrastructure layer for the OpenBB Platform, a data consolidation and integration framework. It provides standardized Pydantic-based models (Data and QueryParams classes) and an API routing mechanism (Router class) that allow developers to build extensions that integrate proprietary, licensed, and public data sources. The package generates both REST APIs and Python packages from these standardized definitions, enabling data to flow to multiple consumption surfaces: Python environments, OpenBB Workspace, Excel, MCP servers for AI agents, and REST APIs for other applications.
The package is explicitly designed as a project dependency for building and extending the OpenBB Platform, not as a standalone tool. It requires Python 3.10–3.13 and familiarity with FastAPI and Pydantic. Its 14 runtime dependencies include FastAPI, Uvicorn, Pydantic, and other stable web and data libraries. After installation and extension, you build the application using the openbb-build command to generate static assets and API endpoints.
Use it for
- Build a custom data provider extension that standardizes queries and responses across multiple financial data sources.
- Create a REST API layer that exposes consolidated data to downstream applications and AI copilots.
- Integrate proprietary or licensed data into a Python environment for quantitative research and analysis.
- Define standardized query parameters and data models for a multi-provider data platform.
- Generate both Python and REST API endpoints from a single standardized data model definition.
