Which maps provide an offline API for finding a route?

Question

OpenStreetMap

There was a problem to search for a route on roads ("optimal" route, ) between two points. There is no possibility to use the online API of known services. Are there any offline maps with an API, even paid ones, that allow you to solve this and similar problems?

Answer 1

The data is also in the open-streetmap (which is in the tag)
wiki.openstreetmap.org/wiki/Routing/offline_routers - the choice of solution.
