MapLight Contribution Search API

About the API

MapLight’s Contribution Search API provides information on contributions to candidates for federal office (President, Senate, and House) starting with the 2008 election cycle. Contributions can be searched by candidate, election cycle, text search of contributor name and contributor employer, and name-standardized organization ids for major contributors curated by MapLight’s data team.

The API is available to anyone who abides by our Terms of Service. It is free for public, noncommercial use with paid licenses available for commercial and private use.
