HPM stands for 'Hits Per Minute'.
We offer unlimited plans, as well as plans with a set HPM limit.
None of our paid plans have any daily or monthly usage caps, and we never charge for usage (e.g 'per element').
1 Hit is defined as:
1 Isochrone
OR
1 Route
OR
1 H3 / Geohash
OR
1 Matrix (1-to-many or many-to-1)
Requests to the Geocoding API or Map Tiles API do not count as hits. There is no limit placed on these endpoints for paid licence plans.
