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.
