Candid (formed from the 2019 merger of Foundation Center and GuideStar) helps social sector organizations advance their missions by sharing information, breaking down barriers, and improving giving. Candid maintains the most comprehensive set of data on U.S. nonprofits, foundations, grants, and philanthropy, and exposes that data through a family of developer APIs — Essentials, Premier, Charity Check, Demographics, Grants, News, Taxonomy, Eligibility, and PDF/Bulk variants — available through the Candid Developer Portal.
