API key required
All/v1/* endpoints require a valid API key. Requests without a key receive a 401 Unauthorized response.
Every SkyTools account — including Free — can create API keys. Your tier only affects rate limits.

- Keep your key secret. Never commit it to source control or expose it in client-side code.
- Use environment variables to store your key in applications.
- Revoke compromised keys immediately in the Dashboard and create a new one.
- Subscription expiry: If your subscription lapses, your keys remain valid but revert to Free tier rate limits (60 req/min). There is a 3-day grace period after expiration before the downgrade takes effect.
