How do I use the PageSpeed ​​Insights API with the Google Python API?

I am currently working on a page api script with a Google Python API client. The API client states that 1000 requests can be completed in a single Batch . However, I am getting 500 errors after 26 requests. Is there any other way to have the limit calculated for PageSpeed ​​Insights?

My current code looks like this:

from apiclient.http import BatchHttpRequest
from apiclient.discovery import build

# URL_LIST = [ 998 lenghthed list of urls ]

def handle_metrics_results(request_id, response, exception):
        if exception is not None:
            # What say you?
            print 'Dude you fail! ' + str(exception)
        else:
            # Do something with result
            print 'Awesome! ' + str(response)

api_key = 'my_api_key'
insights_service = build('pagespeedonline', 'v2', developerKey=api_key)
insights_request_batch = BatchHttpRequest(callback=handle_metrics_results)
for one_url in URL_LIST:
    insights_request_batch.add(
        insights_service.pagespeedapi().runpagespeed(url=one_url))
insights_request_batch.execute()

      

        
        
        
      

    

Could you point me in the right direction? I really don't know what I am doing wrong here.
