Request Body

Analysis parameters.

application/json: object

Name	Type	Input Shape	Values	Description	Value Required
`dateFrom`	string (date)	-	-	First date of the analysis range, formatted as yyyy-mm-dd. A minimum span of 5 days is required after applying daysOfWeek filters.	Y
`dateTo`	string (date)	-	-	Last date of the analysis range (inclusive), formatted as yyyy-mm-dd.	Y
`daysOfWeek`	array<integer>	-	-	Days of the week to include (1=Sunday … 7=Saturday). An empty array includes all days.	N
`excludeLocalRoads`	boolean	-	-	When true, local road categories (residential, living_street, service, unclassified, road) are excluded from results. Only applied when roadTypes is omitted or empty. Defaults to true when omitted.	N
`isDirectional`	boolean	-	-	When true, one record is returned per direction of travel; when false, results are averaged across both directions.	Y
`isMetric`	boolean	-	-	When true, segment lengths are returned in kilometres; when false, in miles. Defaults to the unit setting in your user profile when omitted.	N
`magnitudeBins`	array<number>	-	-	Upper bounds (inclusive, m/s²) of harsh event magnitude bins. The lowest bin starts at 0; the final bin extends to +inf. For example [2.32, 3.54] creates bins (0,2.32], (2.32,3.54], (3.54,+inf).	N
`magnitudeMax`	number	-	-	Maximum magnitude (m/s²) for a harsh event to be included. Must be > 0 and ≥ magnitudeMin. Defaults to +inf when omitted.	N
`magnitudeMin`	number	-	-	Minimum magnitude (m/s²) for a harsh event to be included. Must be ≥ 0. Defaults to 0 when omitted.	N
`roadTypes`	array<string>	-	living_street, motorway, motorway_link, primary, primary_link, residential, road, secondary, secondary_link, service, tertiary, tertiary_link, trunk, trunk_link, unclassified	Road types to include. An empty array includes all road types. When set, excludeLocalRoads is ignored.	N
`vehicleClassIds`	array<string>	-	-	Vehicle class filter IDs from GET /api/v2/filters/vehicle-classes. IDs must use the scheme_vehicleClassIndex_categoryIndex format and share one scheme; IDs that do not name a known vehicle class are rejected. An empty array includes all vehicle classes.	N
`vehicleClassSchemeId`	integer	-	1, 2, 3, 4, 5, 6	Vehicle classification scheme: 1 = VIUS, 2 = GVWR (FHWA), 3 = Truck Weight Classes, 4 = CARB, 5 = Gross Weight Group (custom scheme), 6 = Expansion Factors (custom scheme). Defaults to 2 when omitted. See GET /api/v2/filters/vehicle-class-schemes.	N
`vehicleClasses`	array<object>	vehicleType: string (values: Truck, Passenger, MPV, Bus, Limo, Other, n/a); weightClass: string (values: *, Class 1, Class 2, Class 3, Class 4, Class 5, Class 6, Class 7, Class 8, Class A, Class B, Class C, Class D, Class E, Class F, Class G, Class H)	-	Vehicle class filters. Use an empty array to include all vehicle classes.	N
`zoneIds`	array<string>	-	-	Zones to include, as encoded zone IDs. Provide exactly one of zoneIds or zones (not both).	N
`zones`	array<object>	code: string; iso_3166_2: string; type: string (values: State, County, City, FSA, ZIP, TAZ, CTR, Custom, Segment)	-	Zones to include, each identified by a code, a zone type and a state or province code (iso_3166_2). Provide exactly one of zones or zoneIds (not both).	N
