Navigate to API Keys in the dashboard sidebar to manage your keys.

​
Create a Key

  1. Click Create Key
  2. Enter a name (e.g., “Production”, “Development”)
  3. Optionally set scopes to restrict what the key can access (e.g., completions only)
  4. Optionally set rate limits and spending caps for this specific key
  5. Copy the key — it won’t be shown again
Store API keys securely. Use environment variables or a secrets manager. Never commit keys to source control.

Key Management

  • Revoke — instantly disable a key (takes effect within seconds)
  • Rename — update the display name
  • View usage — see per-key usage statistics, cost, and request counts
  • Edit limits — adjust rate limits and spending caps per key

​
Key Rotation

To rotate a key without downtime:
  1. Create a new key
  2. Update your environment variables
  3. Verify traffic flows through the new key
  4. Revoke the old key
Both keys work simultaneously during the transition.
