Getting Started

In order to use this library you will first need to get a data.gov API key, which you can request here. Once you get an API key you will be allowed to make 1,000 requests to the FEC API per hour. If you want more throughput you can request that your key be upgraded to be allowed to make 120 calls per minute by emailing APIinfo@fec.gov and asking nicely.

Next, you’ll have to install the library:

pip install fec-filing-iterator

Now you’re all set to start exploring campaign finance data! For example:

import json
from fec_filing_iterator import schedules

api_key = '<YOUR_DATA_DOT_GOV_API_KEY>'

params = {
    'two_year_transaction_period': 2020,
    'committee_id': 'C00696948',
}

for filing in schedules('a', api_key=api_key, params=params):
    print(json.dumps(filing, indent=4))

Factories and Iterators

This library only tries to provide an easy way to access and iterate through the paginated results returned by the FEC API. It does not currently attempt to provide a full and consistent interface for retrieving arbitrary subsets of information from the API. Lots of powerful searches and queries can be parameterized through the API, but we leave it up to you to read the FEC’s documentation and find the appropriate parameters yourself.

The main workhorse of the library is the FilingIterator class. Construct it with API credentials, an API endpoint to iterate over, and whatever parameters you want, and you can treat the full set of records as one big iterable.

The library also provides several handy factory functions that will construct the FilingIterator object and configure it for the appropriate endpoint.
