HTTP Error 403: Forbidden

[codemurt]

I'm trying to run this code:

from claude import claude_client
from claude import claude_wrapper
SESSION_KEY = <MY_SESSION_KEY>
client = claude_client.ClaudeClient(SESSION_KEY)
organizations = client.get_organizations()
organizations

but I get this:

WARNING:root:Failed response object: Response(ok=False, data=b'', status_code=None, error='HTTP Error 403: Forbidden')
None

I don't really understand what the problem is.
