The service is free for data providers, users who access this information, and third parties who use our apps to display civic information on their site. Once you register your project in the Developers Console, you may make up to 25,000 queries per day. If you need additional quota, use the Quotas page in the Developers Console for your project to make a request.
Change.org has also used the API to let users post a petition to an elected representative's page. The representative can see how many of their constituents have signed a petition addressed to them, giving them insight into what issues are being discussed in her district and the ability to respond directly.
voterInfoQuery returns data for elections supported by the Voting Information Project. This data may include both official data published and verified directly by a state or local election official along with data collected from official sources by trusted third party partners.
