sec-cik-mapper
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
- Pre-generated mappings, updated daily, available from GitHub and jsDelivr for use outside of Python
- Support for Python 3.6+

Pre-generated Mappings
Pre-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, which fetches, transforms, validates, and uploads the latest mapping data from the SEC to GitHub (save location: sec-cik-mapper/mappings · GitHub). These mappings are available for download and usage from both GitHub and the jsDelivr CDN.
Example Usage
Example curl commands, which download the specified mapping files and saves them to the current working directory:
