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

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

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.

Does the integration allow accessing diversity and inclusion data?

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