FAQ

Questions Candid (GuideStar) owners ask.

  • 01

    Can I verify if a non-profit is eligible for tax-deductible donations?

    Yes! Use the verify_charity_status capability with the organization's EIN. Your agent will fetch the real-time compliance status from Candid's Charity Check API.

  • 02

    How do I find the EIN for an organization if I only have its name?

    Simply ask the agent to search_nonprofits and provide the name. The search results will include the EIN for each matching organization, which you can then use for deeper lookups.

  • 03

    Does the integration allow accessing diversity and inclusion data?

    Yes. Use the get_demographics capability. It will retrieve the DEI metadata provided by the organization to Candid, helping you understand their leadership and staff representation.
