How do I get Charity Navigator API credentials?

Visit [**charitynavigator.org**](https://www.charitynavigator.org/index.cfm?bay=content.view&cpid=6322), register for a free developer account, and you'll receive an App ID and App Key. Both are required for API access.

What does the rating scale mean?

Charity Navigator rates nonprofits on a 0-4 star scale. 4 stars = exceptional performance, 3 stars = strong, 2 stars = adequate, 1 star = needs improvement, 0 = unrated or flagged. Ratings are based on financial health, accountability and transparency.

How do I search for charities by cause?

Use get_categories to get all cause/category IDs, then use search_charities with the category_id parameter. Popular categories include education, health, environment, animal welfare, arts & culture, and human services.

EIN stands for Employer Identification Number, a unique 9-digit identifier assigned by the IRS to US nonprofits. It's used as the primary key for looking up specific charities. You can find EINs in search results or on the charity's tax filings.
