DeepL error 403

Hi. I try to integrate translation an would like to give DeepL a try but i got an error Message:

{“level”:50,“time”:“2023-07-11T13:40:24.441Z”,“pid”:1235,“hostname”:“rocketchat”,“name”:“System”,“msg”:“Error translating message”,“err”:{“type”:“Error”,“message”:“failed [403]{"message":"Wrong endpoint. Use"}”

I have only a free DeepL API key and i guess my problem is related to that. Is it possible to use with the free API key ?
Is there a way to changee the URL for the translation API ?
Are there any free translation services available ?
