Azure Retail Pricing API shows different USD prices for Virtual Machines compared to the prices on azure.microsoft.com/en-us/pricing/calculator/

I would like to get the price of the VM via the Pricing API, but when I compare this price with the price on the pricing/calculator and on the portal - the API price is different.

When I call the Pricing API by https://prices.azure.com/api/retail/prices?currencyCode='USD'&$filter=armSkuName eq 'Standard_D4s_v3' and armRegionName eq 'westus' and priceType eq 'Consumption'
I expect to get the same result, but it is different:
