Body Params

geometry

required

Geometry used in a query, provided as one of the following geometry types:

segment_id: An array of segment IDs
radius: A radius around a point
nearest: Segments nearest to a point
polygon: A bounding polygon
tract_id, zip_id, blockgroup_id, taz_id,: IDs for various local aggregations (US-only)
places_2020: 7-digit FIPS code from the 2020 U.S. census, where the first 2 digits are the state code and the last 5 digits are the place code. (US-only)

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:

year

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 2025.
Use 202601 for metrics from January 2026 and later.
Use two vintages for a date range across years.

osm_vintage

Allowed:

roadway_classification

object

If specified, only segments with the given OSM roadway classifications will be returned.
