Fonctionne EN PARTIE. Pas de mémorisation des préférences. Il semblerait que l'inscription pour une API soit obligatoire. Et ce n'est gratuit que le premier mois...

This review is for a previous version of the add-on (3.8.0). 

It is free for 100 messages / day. Which I think works for most people. There is cost for an API key and more messages, like any service that helps a little bit to pay for servers. Thanks for trying it out.
