Is there a free API for building routes?

Question

Google Maps

Hello!

There is a non-commercial project in which it is necessary to receive data about the route in Russia (travel time) between 2 points in the browser extension (in background or content).
Yandex.Routing and Google API Directions offer only paid integrations, but you don't want to invest yet. https://openrouteservice.org/
has too small limits, I would like a little more. Has anyone come across a similar case?
