Lets you check the date range for which metrics are available for a specified travel mode.
Lets you check how many StreetLight segments are included in your defined geometry, and thus how many segments you would get metrics for if you use the same geometry with the Metrics endpoint.
Returns the StreetLight segment IDs and their associated geometry in the GeoJSON format.
Returns a subset of the segments and their respective geometries from a previous geometry query.
Returns metrics for StreetLight segments within your defined geometry. You can request many types of metrics and filter your results. For more information, see Available Metrics.
Returns metrics for a subset of segments from a previous metrics query.
