In general, access to a particular project is controlled by a unique key provided to the customer for that project only. Most end points in the API take a camera ID , a start time and an end time, and will return averaged statistics collected for each sample within that time range. Sample frequency will depend on what is set for that particular Project, and may be anything from every five seconds to many minutes. All data returned is averages or totals and in metric units.
For details of the data structure for each endpoint and sample output, see the online documentation liked above.
