Cicero API FAQ

We ask that you limit API calls to 200 per minute. For more information about user obligations and rights, please see our Terms of Use

You will need a software developer, or someone who has experience working with a REST API. To see our documentation on how to implement please visit our documentation.

You can contact us by filling out the contact form, or emailing

Credits are the currency of the Cicero API. Credits are purchased in incremental buckets, and then deducted as applicable API ‘calls’ are made.

A call is a line of communication used to ask an API to return a specific result. In the case of Cicero, you might make a call to the legislative_district resource, which will return a response of legislative districts to the location you specified.

We do not charge you for authentication calls or to retrieve election event data. For a full list of API resources and their cost, please visit our documentation.

We offer a Free Trial so users can experiment with integration prior to committing to a paid account. New users are automatically given a free trial when signing up for the API. The free trial provides 1000 credits and expires after 90 days.

We kindly ask that you only sign up for one free trial per organization.
