GuideStar is an information service that reports on IRS-registered nonprofit organizations in the U.S. Their database provides information about each company's finances, impact, governance, reputation, programs, legitimacy, mission, etc.
Non-profits are able to share their complete information through the free Guidestar Exchange, ensuring that information seekers have the most current and accurate data. The GuideStar Exchange API enables developers to use this data supplied by the non-profits and directly integrate into applications and websites.
