finra-py is an unofficial, open-source Python client library for the FINRA API Platform. It provides a lightweight, unopinionated Python interface to the FINRA API while preserving direct access to the API's responses and full functionality for every supported API endpoint and dataset.
The core features include:
- OAuth 2.0 authentication, client creation, token management, and custom token storage
- Equity, Fixed Income, FINRA, Firm, Registration and TRACE Report Card datasets via the Query API
- FINRA notification event datasets via the Notification API
- Submission of regulatory filings and other data to FINRA, including creation, validation, submission, updates, and retrieval for Form U4, Form U5, Form BR, Create Individual, Non-Registered Fingerprint, and other supported workflows via the Submission API
- Support for all credential types
- Support for Mock datasets
- Support for the QA Test Environment API
- Support for asynchronous requests (server-side)
- Support for
asyncio(client-side)
finra-py requires Python 3.11 or later.
Install the package using pip:
python -m pip install finra-pyImport the package in Python:
import finraYou can find a full description of the finra-py library's functionality in the documentation.
For detailed instructions on how to get started with finra-py, see Getting Started.
finra-py is FINRA-specific on the way in, and standard HTTPX on the way out.
- OAuth 2.0 Authentication: The FINRA API uses OAuth 2.0 for authentication and authorization. Implementing the OAuth 2.0 authentication flow yourself can introduce unnecessary complexity and security risks.
finra-pyhandles token acquisition and lifecycle management for you, with customizable token storage for applications that need to manage credentials in their own storage systems. - Direct API Access:
finra-pykeeps the client layer deliberately thin. It maps requests to the FINRA API and returns the rawhttpx.Responseobjects directly to you, without imposing a custom response or data model. You get the convenience of a dedicated FINRA client with all of the API's features, without giving up the control available through direct HTTP requests. - All API Endpoints: The
finra-pylibrary is designed to provide thorough coverage of the FINRA API Platform. With this goal in mind,finra-pyimplements full functionality for every dataset and regulatory filing supported by the FINRA API and described in the documentation. It also provides comprehensive test coverage across Windows, macOS, and Linux.
Even though finra-py strives to provide coverage of all documented datasets for the FINRA API, there are some datasets and services available through FINRA that may not be available through their API. See FINRA Data for information about all available FINRA datasets.
finra-pydoes not currently support FINRA's fileX API
