## Tools (3)

- `compare_nonprofits`: Use this when the user wants 2 to 5 US nonprofits side by side by EIN: latest Form 990 revenue, expenses, net assets, total assets, officer compensation and computed ratios with formulas, plus a PDF, CSV and Excel comparison. Data is live from ProPublica Nonprofit Explorer. Does not rate or rank organizations. Do not use with names; find EINs with search_nonprofits first.
- `get_nonprofit_profile`: Use this when the user wants to check a US nonprofit by EIN: IRS subsection, foundation status, deductibility, ruling date, and a multi-year table of revenue, expenses, net assets, total assets and officer compensation from Form 990 filings, with year-over-year change, ratios and their formulas, filing PDF links, and a PDF, CSV and Excel report. Data is live from ProPublica Nonprofit Explorer. Does not rate or rank organizations and does not give tax or legal advice.
- `search_nonprofits`: Use this when the user wants to find a US nonprofit or charity and its EIN by name, optionally in one US state or one category. Returns up to 25 matches with EIN, city, state, NTEE code and IRS subsection, from ProPublica Nonprofit Explorer. Does not return financials; use get_nonprofit_profile with an EIN for those. Do not use for organizations outside the US.
