CharityAPI vs ProPublica Nonprofit Explorer

Pick CharityAPI when

  • Developers embedding charity verification
  • Donation platforms checking EIN/tax status
  • Grantmakers screening US charities
  • AI agents needing nonprofit lookups

When CharityAPI is not a fit

  • Nonprofits wanting donor management . this is an API, not a CRM
  • Non-technical teams; no UI without a developer
  • Anyone needing international charity data . US nonprofits only
  • One-off manual lookups . free IRS/ProPublica tools cover that
