/v4/h3Calculate the travel times to all H3 cells within a travel time catchment area. Return the max, min, and mean travel time for each cell.
This is a less performant version of the /h3/fast endpoint, but with more configurable parameters and greater geographic coverage.
H3 resolution of results to be returned, values can be in range [6, 12]. Limitations can be found here.
Properties to be returned for each H3 hex. Possible values: min, max, mean.
Searches based on departure time. Leave departure location at no earlier than given time. You can define a maximum of 10 searches.
Used to identify each search in the results array. Must be unique among all searches.
Coordinates of the departure location. Use either latitude and longitude, or the centroid of an h3 cell.
Leave departure location at no earlier than given time. In ISO 8601 format. For example:
2026-03-16T11:00:00Z (representing UTC)
2026-03-16T11:00:00-05:00 (representing New York on Standard Time: UTC-05:00)
Maximum journey time (in seconds).
Maximum value depends on resolution parameter.
Limitations can be found here.
Transportation mode and related parameters. type is a mandatory field, but all other fields are optional and default values are used if not specified.
When enabled, range adds a departure window to the departure time, and a combined shape of all possible journeys departing within the window is returned.
Disabled by default.
Used in public_transport, coach, bus, train and driving+train transportation modes. For other modes range search parameters are ignored.
true(default) - returned cells will not cover large nearby water bodiesfalse- returned cells may cover nearby water bodies like large lakes, wide rivers and seas
Adjusts the process of looking up the nearest roads from the departure / arrival points.
Searches based on arrival time. Arrive at destination location at no later than given time. You can define a maximum of 10 searches.
Define the unions of shapes that are the results of previously defined departure or arrival searches. You can define a maximum of 10 unions per request.
A list of the search ids referring to the shapes to be used for calculating the union.
Define the intersections of shapes that are the results of previously defined departure or arrival searches. You can define a maximum of 10 intersections per request.
Used to identify each search in the results array. Must be unique among all searches.
A list of the search ids referring to the shapes to be used for calculating the intersection.
