I want to use the routes API to create isochrone maps that show where its faster to take transit than drive. I want to save these maps and share them but I don’t know if this breaks the rules in terms of caching data. I would delete the raw data but keep the shape files/kmls that result. They show where in the city biking to a destination is faster than driving for example.
Thanks for posting @steven_squire!
Just to confirm: Are you using Apigee for this? If so, please edit your question to clearly state that you are using Apigee and how it relates to your concern, so our community can better help! 
Hello @steven_squire,
I’d say no 
Not because of the Route API but because it seems that you can’t use any Google Maps data outside of Google Maps itself.
From Google Maps Platform FAQ, Can I create an application that includes Google Maps Platform data in a document:
If your application generates a document, either in electronic or printed form, no data from Google Maps Platform, including images, may be included in the document. See the Google Maps Platform Terms of Service “No Scraping” section for more details.
Check the 3.2.3 Restrictions Against Misusing the Services section from Google Maps Platform Terms of Service.
Also, from Google Maps Platform Service Specific Terms, 15. Routes API:
15.1 Use without a Google Map. Customer may use Google Maps Content from the Routes API in Customer Applications without a corresponding Google Map.
15.2 No use with a non-Google map. Customer must not use Google Maps Content from the Routes API in conjunction with a non-Google map.
15.3 Caching. Customer may temporarily cache latitude (lat) and longitude (lng) values from the Routes API for up to 30 consecutive calendar days, after which Customer must delete the cached latitude and longitude values.
That said, Google appears to be relatively open when it comes to Printing and Web & Apps, as long as you comply with the General Guidelines & Fair Use.
However, Google Maps still seems to function as a monolithic application, one that cannot be used or extracted from its own ecosystem, data included.
You must also ensure proper required attribution is provided.

Thank you for your perspective and the links. The no creating content from google maps content and the no scraping seem to rule this application out. I would still like some more clarity, I may reach out to a google sales person
