Is the as api really free or are there free tier usage limits/non free licence restrictions on the api which aren't compatible with the image license? (Asking as I've seen this elsewhere...)

It used to be. However, seems they have now restricted the ability to generate keys to authenticate.

I am awaiting their response to my question about obtaining a key. Keep an eye on this post, I'll update with their reply (if any): https://www.trekview.org/blog/2021/playing-with-kartaview-ap...
