Added a 'Distance Matrix' Endpoint to the Unit Map REST API.

What’s changing?

We’ve introduced a new “Distance Matrix” endpoint to the Unit Map REST API. This endpoint calculates distances and estimated travel times between one or more source points (nodes) and one or more target points (nodes) on a Unit Map. For each source–target pair, the service returns the shortest navigable path distance (in feet) and estimated travel time (in seconds). This update went live in January 2026.

What to expect:

API consumers can now perform multi-point distance and travel-time calculations directly through the Unit Map API. This enables use cases such as calculating distances from a unit to multiple amenities, comparing multiple units to multiple points of interest, and building proximity-based sorting or filtering experiences.

This unlocks new product experiences like identifying the closest amenities, enabling relative distance comparisons, and supporting navigation-based proximity logic across Unit Map and SightMap experiences. NOTE: The Unit Map must have navigation data for this endpoint to function properly.

What do you need to do?

Before using this endpoint, ensure:

• Your Unit Map supports navigation.

• The unitmap.distances.calculate API permission is enabled for your key.

• The Experimental-Flags: distances header is included in your API request.
