**sec-cik-mapper** is a Python package for generating mappings between stock and mutual fund identifier data provided by the SEC.

Features
--------

- Generate up-to-date mappings from the SEC as native Python dictionaries
- Mappings for both stocks and mutual funds
- Mapping data exposed as a raw pandas dataframe for custom data processing and usage
- Full support for PEP 484-style type hints and the `mypy type checker <https://mypy.readthedocs.io/en/stable/>`_
- `Auto-generated mappings <https://github.com/jadchaar/sec-cik-mapper/tree/main/auto_generated_mappings>`_, updated daily, available from GitHub for use outside of Python
- Support for Python 3.6+

Supported Mappings Identifiers
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Mappings can be formed between the following SEC identifiers and company metadata:

**Stocks**

- CIK
- Ticker
- Exchange
- Company Name

**Mutual Funds**

- CIK
- Ticker
- Series ID
- Class ID

Auto-generated Mappings
-----------------------

Auto-generated mappings are also available for download and use outside of Python (e.g. manually or via automated
scripts/curl requests). These mappings are updated daily via a `fully automated daily CRON job <https://github.com/jadchaar/sec-cik-mapper/actions/workflows/update_mappings_daily_cron_job.yml>`_,
which fetches, transforms, validates, and uploads the latest mapping data from the SEC to GitHub
(save location: `github.com/jadchaar/sec-cik-mapper/auto_generated_mappings <https://github.com/jadchaar/sec-cik-mapper/tree/main/auto_generated_mappings>`_).
These mappings are available for download and usage from both GitHub and the `jsDelivr CDN <https://www.jsdelivr.com>`_.

Example Usage
^^^^^^^^^^^^^

Example `curl <https://curl.se/>`_ commands, which download the specified mapping files and saves them to the current working directory:
