The data source that will be used. Check the Available Metrics and Date Ranges for each data source. Requests that do not specify this parameter will use lbs_plus. For more information, see What are data sources? .

Allowed:
integer
2000 to 2099

Specify the year for which you want metrics to get the relevant geometry; this ensures that the segments in the road network used are consistent with the year you are querying.

osm_vintage
array of integers

The OpenStreetMap (OSM) snapshot that defines segments queried, where 202302 is February 2023 and 202501 is January 2025. Only required for the agps data source.

  • Use 202302 for metrics from December 2024 and earlier.
  • Use 202501 for metrics from January 2025 and later.
  • Use both vintages for a date range across 2024 and 2025.
