# Rate limits

Autosheet extensions rely on services that enforce rate limits to ensure smooth and fair access to everyone.

If you choose not to set up API keys, you will share rate limits with other Autosheet users. By setting API keys, you benefit from your own rate limits, which you can manage from these links:

**Google rate limits:**

If you use the GPT for Sheets – Autosheet add-on, you are also subject to the [rate limits enforced by Google](https://developers.google.com/apps-script/guides/services/quotas), based on your type of account:

|                      | External service calls daily limits (URL fetch) |
| -------------------- | ----------------------------------------------- |
| **gmail.com**        | 20k / day / gmail.com account                   |
| **Google Workspace** | 100k / day / Google Workspace account           |

> **Info**

> **Google's rate limits apply to all add-ons and scripts**, not just ours. If you use multiple scripts or add-ons, your usage counts towards the same rate limits. GPT for Excel – Autosheet and GPT for Word are not affected by Google's rate limits.
