IRS Charity Data should be free

We make this data available as cheaply as possible because we believe people build great things for charities, and that should be as easy as possible.

Competitors charge hundreds of dollars a month.
Charities rely on "Free for Charities" tiers, we're encouraging companies to offer a free tier for charities and making it as easy as possible to verify charitable status.
We built the IRS data ingestion pipeline including data cleaning, managing exceptions, and converting to json so you don't have to do those bugfixes.
