**Connect your own API keys for model providers so chats using those models bypass AgentSky's billing for that model.**

Vendor accounts (also called Bring Your Own Key) let you supply your own API key for a model provider. When AgentSky routes a chat through your key, model token costs are charged to your provider account, not your AgentSky balance.

1. Open Settings › Agents and apps › Bring your own subscription.
2. Click Vendor accounts.
3. Add your API key for the relevant provider.

Where: Settings › Agents and apps › Bring your own subscription › Vendor accounts (web and Mac).

Good to know: BYO API keys and BYO subscriptions (Claude/ChatGPT plans) are separate — you can use either or both. You still need AgentSky credits for compute, tools, and connectors regardless of which model billing you use.
