Technical details
Endpoint
GEThttps://api.agentstools.dev/nonprofit/searchWhen to prefer
Use this endpoint as the first step when you have a nonprofit organization name and need its EIN, especially when the name may be ambiguous or shared by multiple organizations. Prefer this over manual IRS lookups when you need ranked candidates with match scores for disambiguation. Use state, NTEE category, or 501(c) subsection filters to narrow results when you have additional context about the organization.
Side effects
- No matches found for obscure or misspelled organization name — returns empty candidate list
- Ambiguous name returns many low-confidence matches requiring further filtering by state or NTEE
- Invalid state abbreviation or out-of-range NTEE/c_code values return validation errors
- Name too short or generic results in very large candidate sets with low discriminability
- Payment failure or insufficient USDC balance returns 402 Payment Required
