Shreyansh 7b7f012aa9 fix(finra): use persistent session to prevent TooManyRedirects (#7443)
* fix(finra): use persistent session to prevent TooManyRedirects

Resolves #6972.

The FINRA OTC data fetching functions (get_finra_weeks, get_finra_data,
get_full_data) previously created new HTTP sessions for each request.
When making dozens of sequential API calls to aggregate weekly data,
this caused Cloudflare's bot protection on api.finra.org to trigger
redirect loops, resulting in a TooManyRedirects error.

Changes:
- Refactored get_finra_weeks and get_finra_data to accept an optional
  session parameter via kwargs.
- Updated get_full_data to create a single requests.Session and perform
  a pre-flight GET to finra.org to establish Cloudflare cookies before
  making API calls.
- The session is reused across all requests within a single data fetch
  operation, preventing the redirect loop.
- Removed hardcoded User-Agent from get_finra_data in favor of the
  platform's standard user agent set by get_requests_session.
- Increased timeout for weeklyDownloadDetails from 3s to 20s for
  consistency and reliability.

* perf(finra): use async requests for concurrent weekly data fetching

Addresses reviewer feedback on PR #7443.

The get_full_data function previously made up to 52 sequential POST
requests to fetch weekly OTC data, resulting in poor performance.

This commit adds async equivalents (aget_finra_weeks, aget_finra_data,
aget_full_data) that use the platform's amake_request utility and
asyncio.gather to fetch all weeks concurrently through a shared
aiohttp session.

The FinraOTCAggregateFetcher now uses aextract_data, which is natively
supported by the platform's Fetcher base class.

The pre-flight GET to finra.org for Cloudflare cookie establishment
is preserved in the async path.

* fix(finra): return all rows from data fetching instead of just the first one

* run black, add symbol field to data model, and recapture test cassette

* mypy

API keys

To fully leverage the OpenBB Platform you need to get some API keys to connect with data providers (listed above).

Here's how to set them:

Local file

Specify the keys directly in the ~/.openbb_platform/user_settings.json file.

Populate this file with the following template and replace the values with your keys:

{
  "credentials": {
    "fmp_api_key": "REPLACE_ME",
    "polygon_api_key": "REPLACE_ME",
    "benzinga_api_key": "REPLACE_ME",
    "fred_api_key": "REPLACE_ME"
  }
}

Runtime

Credentials can be set for the current session only, using the Python interface.

>>> from openbb import obb
>>> obb.user.credentials.fred_api_key = "REPLACE_ME"
>>> obb.user.credentials.polygon_api_key = "REPLACE_ME"

Go to the documentation for more details.

REST API

The OpenBB Platform comes with a ready-to-use REST API built with FastAPI. Start the application using this command:

uvicorn openbb_core.api.rest_api:app --host 0.0.0.0 --port 8000 --reload

API documentation is found under "/docs", from the root of the server address, and is viewable in any browser supporting HTTP over localhost, such as Chrome.

See the documentation for runtime settings and configurations.

Local Development

To develop with the source code, you need to have the following:

  • Git
  • Python 3.10 - 3.13.
  • Virtual Environment with poetry installed.
    • Activate your virtual environment and run, pip install poetry.
  • A local copy of the GitHub repository

Install the repository for local development by using the installation script.

  1. Activate your virtual environment.
  2. Navigate into the openbb_platform folder.
  3. Run python dev_install.py -e to install all packages in editable mode.

See the documentation for an overview of the architecture and how to get started building your own extensions.
