Hi @mh-trimble, thanks for reporting this. I asked around internally and I believe the reference documentation for maps libraries are in the process of being migrated to the new URL (it may be something like: developers.google.com/maps/reference/documentation/{places|routing|address}/...) and should be up in the next few months. Apologies that the transition hasn't been smooth. Can you point us to the place where you found https://cloud.google.com/java/docs/reference/google-maps-places/latest/overview?

Also, regarding API-Keys: I believe our client libraries don't have the best built-in support for Api-Keys (as of now). I think we have a way to enable it and are looking into ways to make this better.

CC: @blakeli0 @alicejli if you have a way enable ApiKeys now for client libraries and any updates regarding ApiKeys in general.

Here is the link to the "javadocs" in the readme

I agree it's not straightforward to set up API Keys at this moment, and it is not documented either. I created a separate issue #10921 to track the documentation effort.
