Provider Questions
Section titled “Provider Questions”Do I need an API key for every provider mode?
Section titled “Do I need an API key for every provider mode?”No. OpenAI and Anthropic API key modes require keys. Claude Subscription and Codex Subscription modes use subscription access and do not require an API key in ExtraBrain.
What should I check if provider validation fails?
Section titled “What should I check if provider validation fails?”Confirm the key, model access, base URL, subscription status, and network access. Custom endpoints also need the exact model name expected by the endpoint.
