Provider API keys are credentials from AI service providers like OpenAI, Anthropic, or ElevenLabs. Adding your own keys lets you override platform defaults and route usage to your billing accounts.

Yes. Enter your API key in the Provider API Keys section. The platform will use your key for LLM requests, and costs will be billed directly to your account.

When you add your own API key, all requests to that provider are routed through your account. You pay the provider directly according to their pricing. The platform does not add markups.

Yes. All API keys are encrypted at rest and in transit. Keys are never exposed in logs, dashboards, or API responses. Only authorized workspace admins can view or manage keys.
