Read the usage policies first.

Warning confirms that no restriction, No ?

My API was not working. There is a message saying that the trial period is ended. I just enabled Billing and it is now working again.

OK, OK, OK, thank you all for your kind cooperation. In fact I was using an Api Key which was not a Maps Api Key.
Everything is written in English, it's not always easy for me, who doesn't speak Shakespeare's language, to understand correctly.
Last question. So I created a Maps Api Key and now it works fine. It looks like I created this API Key for free and probably for a trial period. So I imagine it is only temporary. What is the procedure to be able to use it definitively. I could not find the section to convert it.
Thank you again and please excuse me for the inconvenience and for my poor English with Google Translate.

If you want to convert the place name into coordinate then you should use the Places API.
