Well, yes I can create isochrones myself indeed. What I meant is the ability to generate them via an API without having to handle any GIS / routing data yourself and this for any city. Handling these kind of services takes a lot of time, especially if this is only a sub-part of a more generic product. Thanks for the alternatives though

  The second option can be hosted at ArcGIS Online without you doing anything (i.e. loading anything). It is a REST API. Yes, it is hidden in their stupid docs. The third option is faster than anything else, but would require you to load planet-osm.

    Ha, didn't know that. I'll look deeper into the docs then. Thanks!

  100% agree. I used their isochrone API several times for consulting work.
