Thanks Sam,

Easier for some than other. I am in the latter category 😂

I am fiddling around with this and haven’t got this to work. I have no tool experience so actually looking forward to getting this working to think about other ways to use tools.

I tried using the code from your blog with an API key which did not work. AI suggested I use a hard coded url so I tried that without success.

The API Key was not called and there are no logs that were created with errors.

This is what I tried.
