I am trying to pull the next page of results from this link.

There are 503 total results, so I need results 501-503.

I am pulling the first page using this:

import json
import requests
api_url = 'https://investor.vanguard.com/investment-products/mutual-funds/profile/api/VFIAX/portfolio-holding/stock.json'
get_server_information = requests.get(api_url)
json_data = get_server_information.json()
pretty_data=json.dumps(json_data,indent=4)

I am trying to pull the next set using the links that have start=501&count=500, but no luck. I tried also using page=0, page=1, no luck. When I use start=501 or next or next_page, it is still pulling the first 500.

Here is what does not work:

import json
import requests
api_url = 'https://investor.vanguard.com/investment-products/mutual-funds/profile/api/VFIAX/portfolio-holding/stock&start=501'
get_server_information = requests.get(api_url)
json_data = get_server_information.json()
pretty_data=json.dumps(json_data,indent=4)
