Security

• OAuth tokens are opaque and stored hashed; access tokens last 1 hour, refresh tokens rotate on every use. Disconnect any app in Account → AI agents.
• A token or key acts as your account (same credits and limits as the web app). Up to 120 calls per minute per key.
• Agents never post to social media for you: they make and fetch clips, you post.
