The Wait Time Calculator is a simple API that allows users to clock wait times at polling locations around the US. The API also lets users report this data and display it on a Google map. Developers can use this information in their own applications and websites. The API returns poll locations by address or latitude and longitude, optionally returning wait times, national wait time statistics, by state, or for a specific poll location, and record a wait time for a specific poll location. The API uses RESTful calls and responses are formatted in JSON.
