I got the key with the free basic service and I'm fine.I see that their javascript based api is being a pay model these days. ($7/1000 requests)
Are there alternatives that just can display a route on a map that still functions correctly and is free?
I just want to verify .gpx data.
In Erel's instructions he explains how to create a free API keythen it's probably using the embedded method.
I'll give it a try.
