Get All Veeqo Products Via API

I am trying to get all the products via this call : https://api.veeqo.com/products?page=1&page_size=100
I am getting products upto 350 page and thereafter getting no products.
We have 47k products, So atleast it should work upto 470 pages like this : https://api.veeqo.com/products?page=470&page_size=100 but I am getting only 35k products and remaining 12k are missing. How do I get full list of 47k products via API?
