You were the one to contact them to begin with, so I'd hope you'd also be the one to ask about modifications to their service offerings.

To say python wasn't designed for the web is a bit preposterous.    Most modern languages weren't "designed" for the web.  The web itself wasn't "designed for the web" its just a melting pot of technology.  (Read up a bit on the history of JavaScript). :)

But please ask on behalf of the project.  You took a lead role in creating this service, please follow through.
