Random bad request error when starting to get data from the API

My web app used to work fine for weeks and suddently I get bad request errors when getting data from the API.

I usually get an error between the second and the 5th pages requested. It happens on the production server and in my home development environment.

Here is the website:

Here is the code to get the data:

    public static IQueryable<Item> ListItemDetails { get; private set; }
    public static IQueryable<Price> ListPriceDetails { get; private set; }

    public static async Task<bool> GetData()
            using (var webClient = new WebClient())
                 var tempPrices = new List<Price>();
                 var tempItems = new List<Item>();
                 var jsonData = await webClient.DownloadStringTaskAsync("https://api.guildwars2.com/v2/commerce/prices/");
                 var listItems = JsonConvert.DeserializeObject<List<int>>(jsonData);
                 var totalPagesCount = listItems.Count / 200;
                 for (var pageCount = 0; pageCount <= totalPagesCount; pageCount++)
                       jsonData = await webClient.DownloadStringTaskAsync($"https://api.guildwars2.com/v2/commerce/prices?page={pageCount}&page_size=200");
                       jsonData = await webClient.DownloadStringTaskAsync($"https://api.guildwars2.com/v2/items?page={pageCount}&page_size=200");
                  ListPriceDetails = tempPrices.AsQueryable();
                  ListItemDetails = tempItems.AsQueryable();
        return true;

    The Wiki has a warning atm:

    The Guild Wars 2 API is experiencing difficulties this weekend, which may affect various pages on this wiki such as Dailies, Trading post prices and Maps.
