# Check API Response Time

Check API Response Time asserts a network request finished within the seconds you set. Use it to guard backend speed for a specific URL pattern captured during the run.

## When to use it

* Confirm a search or autocomplete request stays fast after a UI change.
* Watch server wait time separately from total download time.
* Run after the action that triggers the request so the network entry exists.
