I was able to save the Youtube thumbnail URL to a local file without using quata, is that a problem?

I used Youtube Data API to get thumbnail image URLs of Youtube videos.I was able to copy the file to a local file using the thumbnail image URL with the daily Quota amount exceeded.

Here is the python code

import urllib.request as reqreq.urlretrieve("Thumbnail_URL", f". /{Folder_Name}/{Video_Name}.jpg" )

I was able to copy the thumbnails to a local file with the daily quota amount exceeded, is this a problem?

If there is no problem, please tell me why.If there is a problem How can I save thumbnail images to local files without problems?
