+[^1]: Rate limits are enforced with a fixed **per-second fill rate**. For example, a limit of 60 requests per minute translates to **1 request per second**. This means you cannot send all 60 requests at once; the API expects them to be spread evenly over the minute. If your account has a custom higher limit, it will also be enforced as a per-second rate.
 
 :::note[Note on browser timeout]
 By default, a browser will time out if it does not get any [devtools](https://chromedevtools.github.io/devtools-protocol/) command for 60 seconds, freeing one instance. Users can optionally increase this by using the [`keep_alive` option](/browser-rendering/platform/puppeteer/#keep-alive). `browser.close()` releases the browser instance.
