The ProPublica Nonprofit Explorer API provides an application programming interface to the search engine and database that powers Nonprofit Explorer.
The Nonprofit Explorer includes data on 1.6 million nonprofits, including the name, location, and category of each organization.
When available, the API returns data from nonprofit tax returns processed by the IRS during the 2012-2015 calendar years. This information -- available for more than 750,000 organizations -- generally consists of filings for the 2011-2014 fiscal years, but may include older records. The IRS data release includes only a subset of what can be found in the full Form 990s.
ProPublica has linked to PDFs of full Form 990 documents wherever possible, consisting of a separate release by the IRS of Form 990 documents processed by the agency through June 2016 (these documents may contain filings as recent as the 2015 fiscal year.)
Nonprofit Explorer has organizations claiming tax exemption in each of the 27 subsections of the 501(c) section of the tax code, and which have filed a Form 990, Form 990EZ or Form 990PF. Taxable trusts and private foundations that are required to file a form 990PF are also included. Small organizations (those with less than $50,000 in revenue) that file a Form 990N "e-Postcard" are not included in this data.
No API key is required, but commercial users should contact ProPublica.
The following is a list of historical changes that were made to this asset. Typically, once an API is published on ProgrammableWeb.com, the data we keep about that asset gets updated over the course of its life. For example, the endpoint or home page of the documentation might change. As a means of enforcing the integrity of our data, every time a non-trivial change is made to the data we keep about an asset, we require the entry of some changelog text before that change can be saved. This way, we have a great audit trail of all activity surrounding the asset. For each asset, the changelogs begins with the moment an asset is approved for publication on ProgrammableWeb. If you spot an error in our data and believe that a record needs to be updated in some way, the ProgrammableWeb team would very much like to hear from you at email@example.com
