We provide the data and stay out of your way. Teams use CharityAPI as the nonprofit data layer inside the products they ship.
Confirm an organization's IRS standing and tax-deductibility from an EIN — for compliance, onboarding, and due diligence.
Let charities unlock a free or discounted plan by entering their EIN, and verify eligibility automatically in the background.
Populate donation platforms, grant tools, and CRMs with accurate organization records, search, and autocomplete.
We built the IRS ingestion pipeline — the downloads, the data cleaning, the exception handling, the conversion to clean JSON — so you never have to. A handful of endpoints cover what most products actually need.
Retrieve everything the IRS has on file for a nonprofit by EIN (Tax ID).
Fast, typo-tolerant search across the full set of US nonprofits.
A single call that answers the question you actually have: are donations to this organization tax-deductible?

Every field is documented in the API docs.
The larger players are expensive, sales-gated, and bundled into a dozen products. We took the opposite approach on purpose.
We serve the IRS source data as it is — no black-box "integrity scores" or health ratings you can't audit. You build on the ground truth and apply your own judgment.
We don't move money or run donations. We're pure data infrastructure, so donation platforms, fintechs, and CRMs can build on us without funding a rival.
Self-serve signup, transparent pricing, and a real free tier — not a $5,000 minimum and a procurement cycle. Get a key and make your first call in minutes.
Organization records come directly from IRS data — cleaned, structured, and kept current with each release, with no third-party guesswork layered on top.
Start on the free tier and scale when you're ready. No sales call required.
