JSON API /v4/time-filterTravel Time Matrix (Time Filter)
Create a distance matrix with the travel times and distances between thousands of locations in one go.
Supports two HTTP request types:
- GET - for simple requests using basic parameters only
- POST - for more complex requests using advanced parameters
With both request types, to create a many-to-many matrix you will need to use multiple searches.
For example given three points A, B, C you would need three arrival searches - one for each point.
- A -> { B, C }
- B -> { A, C }
- C -> { A, B }
Access URL: https://api.traveltimeapp.com/v4/time-filter
POST Request
A POST request should be used for any of the following use cases:
- Using advanced parameters not available in the GET request
- Calculating a many-to-many matrix
The access URL is the same as the GET request format, but the differences are:
- Authentication is included in the request Headers
- Parameters are included in the request Body

Maximum journey time (in seconds). Maximum value is 14400 (4 hours) as standard. To discuss increasing this, please contact sales@traveltime.com.
array[string]
Properties to be returned for each arrival location. Possible values:
travel_time,
route,
distance (driving, walking and cycling modes only),
distance_breakdown (driving, walking and cycling modes only),
