How this service works
Resolve a US nonprofit name to ranked candidate organizations, each with EIN, name, city, state, decoded NTEE, subsection and a match score. The cheap first step for EIN-to-name disambiguation, optionally narrowed by state, NTEE category or 501(c) subsection.
Output
A ranked list of candidate US nonprofit organizations matching the search name, each containing the EIN, organization name, city, state, decoded NTEE category label, 501(c) subsection code, and a numeric match score indicating relevance.
Example use cases
Verify donor's target charity
“I need to confirm the EIN for a nonprofit called 'Doctors Without Borders USA' before I process a donation — can you search for it and show me the top matches with their EINs and states?”
Disambiguate similarly named nonprofits
“I'm trying to figure out which 'United Way' chapter is based in Los Angeles, CA — can you search for United Way filtered to California and return up to 10 candidates so I can pick the right one?”
Find health-sector nonprofits by name
“Search for a nonprofit named 'St. Jude Research' in the health NTEE category — NTEE id 3 — and give me the top 5 matches with their EINs and locations.”
Technical details
Endpoint
GEThttps://payai.agentstools.dev/nonprofit/searchWhen to prefer
Use this endpoint as the first step when you have a nonprofit name and need to resolve it to a canonical EIN for further downstream lookups or financial transactions. It is ideal for name-to-EIN disambiguation workflows, especially when you can narrow by state or NTEE category. Prefer it over manual IRS searches or unstructured web lookups because it returns structured, ranked candidates with match scores at low cost ($0.008 per call).
Side effects
- No results returned when name is too vague or misspelled
- Ambiguous matches when many organizations share similar names — requires state or NTEE filter to narrow down
- Invalid state code or out-of-range NTEE/c_code values may cause a 400 error
- Rate-limit or payment failure if USDC balance is insufficient (x402 payment required)
- Very new or obscure nonprofits may not appear if not yet indexed in the underlying IRS dataset
