Matt is correct that you can use the offset parameter but his linked documentation and sample url was a little off.

It looks like you're using the venues/explore endpoint, you can find documentation on this here: https://developer.foursquare.com/docs/venues/explore

To page through results you would set up something like this:

https://api.foursquare.com/v2/venues/explore?client_secret=****&client_id=****&v=20161101&limit=50&near=San Francisco, CA&section=food

In your response (json) you should inspect the json['response']['totalResults'] value to see how many results there are in total.

for (var i = 0; i < totalResults/50; i++) {
    url = 'https://api.foursquare.com/v2/venues/explore?client_secret=****&client_id=****&v=20161101&limit=50&near=San Francisco, CA&section=food&offset='(i + 1)*50';
}

It also looks like some of the parameters that you're using are invalid.

1. The near parameter should be San Francisco, CA not San Francisco, San Francisco
2. There is no novelty parameter with that API, do you mean to use limit?

You should use the offset parameter in order to page through the venues:

Here is the API docs: https://developer.foursquare.com/docs/venues/listed

The stated limit is 200 so the example below will return a list of results 201-400: https://api.foursquare.com/v2/venues/?limt=200&offset=201

for (var i = 0; i < numberOfPages; i++) {
    url = 'https://api.foursquare.com/v2/venues/?limt=200&offset=' + i * 200;
}
