How this service works
US nonprofit organization search by name and state - EIN, city, NTEE category and tax-exempt status from IRS Form 990 data via ProPublica Nonprofit Explorer
Output
A JSON object containing the interpreted query string, optional state filter, total match count, number returned, data source attribution (ProPublica), an optional caveat note, and an array of matching organizations each with fields such as EIN, name, city, state, NTEE category, and tax-exempt status.
Example use cases
Grant application EIN lookup
“I need to fill out a grant application and I need the EIN for Feeding America in Illinois — can you search for it and give me the exact EIN and their NTEE category?”
Charity vetting before donation
“Before I donate, can you check if 'Friends of the Library' is a registered tax-exempt nonprofit in California and tell me their city and exempt status?”
Nonprofit directory research
“I'm building a list of environmental nonprofits in Colorado — can you search for organizations with 'conservation' in the name and return up to 25 results with their EINs and categories?”

Endpoint
GEThttps://saylorinnovations.com/api/nonprofits/search?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to look up US nonprofit organizations by name keyword with optional state filtering and want structured IRS Form 990 data including EIN, NTEE category, and tax-exempt status. It wraps ProPublica's Nonprofit Explorer data, making it ideal for grant research, due diligence, charity verification, or building nonprofit directories without needing direct ProPublica API access.
Side effects
- No results found for obscure or misspelled organization names
- ProPublica upstream API unavailability causing empty or error responses
- State code not recognized if not a valid two-letter US abbreviation
- Limit parameter out of range (must be 1–25) may return default or error
- Common names may return many matches requiring further filtering
