Querying prices for Azure Spot VMs

Question

Is there a way to query the current Azure Spot VM price for a specific VM family/type + region?

Answer 1

Hi,

Azure Spot VMs pricing are not constant and the pricing changes periodically. As of now, there are no established API available for the consumers to check the current pricing for Spot instances.

But you can check the pricing from Azure portal. You need to select Create New VM --> Select Region and Azure Spot to Yes --> Click on Change Size.

You can see the current price for each size in the region which you have selected.

Answer 2

There's now a public API that will return pricing, including that for Spot VMs - https://learn.microsoft.com/rest/api/cost-management/retail-prices/azure-retail-prices

The result set is large, so I'd highly recommend using filtering to only request prices for VMs and Consumption pricing; e.g. https://prices.azure.com/api/retail/prices?$skip=0&$filter=serviceName%20eq%20%27Virtual%20Machines%27%20and%20priceType%20eq%20%27Consumption%27

The API does return the results in batches (up to 100 at a time when I tried), so you'll need a mechanism to handle paging to get all the results.
