# Rate limiting

To keep the VARIO Cloud API fast and reliable for everyone, we apply rate limits to API traffic.

### Limit

**40 requests per 6 seconds**

If you exceed this limit, the API will respond with **HTTP 429 (Too Many Requests)**.

{% hint style="info" %}
Note: Rate limits may evolve over time as the platform grows. If you have a use case that requires higher throughput, please contact us.
{% endhint %}

### What happens when you hit the limit?

When the rate limit is exceeded:

* Requests may be rejected with **429 Too Many Requests**
* You should **pause** and **retry** after a short delay
* Repeated bursts without backoff will continue to be throttled
