Hi @elias444, in order to get help, you need to provide the api URL you are using that causes the error. Hide your private api key with a string like "API_KEY" or "xxxxxx".

{ "status_code": 7, "status_message": "Invalid API key: You must be granted a valid key.", "success": false

Here is the api Getting Started page. There are no tutorials here. You can probably find some by searching on the internet.
