I’m having trouble trying to get claude code to use the AI gateway with Unified billing. I’ve configured claude settings.json with the BASE_URL and the CUSTOM_HEADERS, but it also seems to always need an AUTH_TOKEN. I then get a 401 on the gateway, and the gateway doesn’t make it super obvious if I’m failing to auth with cloudflare or if the AUTH_TOKEN is then being passed on without unified billing - has anyone tried this so far?
