"Invalid bearer token" when using Anthropic API
Describe the bug
When using Anthropic API with the API key correctly added, below error message appears:
Error code: 401 - {'type': 'error', 'error': {'type': 'authentication_error', 'message': 'Invalid bearer token'}}
My API key has been tested to work in other places.
Expected behavior
The newly added Anthropic instance should work.

I think I found the issue. Calls are to anthropic do not contain the expected headers. Currently, alpaca uses the Authorization: Bearer some-api-key method. However, account to the anthropic docs, the expected header is x-api-key some-api-key.
I am working on a fix, will see if I can get the patch merged.
Alpaca does not use Authorization: Bearer API explicitly, most instances including Anthropic are managed using OpenAI's libraries
As in removing Anthropic as an option completely? That would be a pity... it's quite a big provider.
Hi everyone, I didn't end up removing Anthropic and instead waited to see if they would support OpenAI's sdk directly.
It seems like they have been supporting it for quite a bit so I'm going to close this issue, if there are still problems please tell me and I'll see what I can do.
