Please Help! n8n says my API key is wrong (I have replaced it with a new key 5 times)

Thank You For Clicking!

So, I am trying to create an HTTP Request to upload an image and paste a prompt at the same time.

I am currently trying to connect this to Claude, but I would be open to using any LLM that I could get an image and prompt into simultaneously.

If someone could please tell me where I am going wrong, I would greatly appreciate it.

Thank you again for your help!

You should remove the authentication and set only the header, something like:

In the second screenshot you seem to be sending the request to Anthropic. Why send an n8n auth key to a request to someone else? That looks incorrect to me.
If it’s the anthropic key, then please ignore what I just said, and follow the above mentioned advice
