Is there a billing API that can be used to track the azure usage?

Not at this time. You have to log into  https://mocp.microsoftonline.com with your Live ID to see whats going on from time to time. This thread  has good explanation on how to decipher the bill...

Thanks - disappointed that there is no API!

Ruchee (and everyone else) please upvote this response if you are interested in an API. I am investigating this right now from the Microsoft side.

Thanks Bilal! We are really interested in this functionality - any idea when can we expect this API?

Ruchee, I can't promise a date but it's high on our list of "most asked for" features

Hi Bilal,

Lot of good stuff in June 7th release - any updates on the billing side?

Thanks,

Ruchi

From the billing side, we now support Azure purchases in 48 new countries. Plus, we added the ability to download your usage history over a longer period of time. More coming :)

Hi RucheeG,

We have released two Azure Billing APIs, that can help you retrieve Azure consumption details and the list of resources sold along with their associated rates.

Here is a set of helpful pointers that you can get started with:

High-level   article describing the IT Financial Management scenario with Azure Billing   APIs	https://azure.microsoft.com/en-us/documentation/articles/billing-usage-rate-card-overview/
ScottGu's   blog post describing the Azure Billing APIs	https://weblogs.asp.net/scottgu/new-azure-billing-apis-available

please shoot me an email at mobandyo@microsoft.com if there is anything else that we can help with.

Hello, 

     I was able to get the Usage API working, but am getting invalid expression query for the Billing API. I have followed instructions from the Microsoft site. The query I am using is as follows:

"https://management.azure.com/subscriptions/$subscriptionId/providers/Microsoft.Commerce/RateCard?api-version=2015-06-01-preview&`$filter=OfferDurableId eq MS-AZR-0023P' and Currency eq USD and Locale eq en-US and RegionInfo eq US"

I am using powershell to construct the REST API stuff as referenced from: http://blogs.technet.com/b/keithmayer/archive/2015/06/28/export-azure-subscription-usage-with-new-billing-api-and-powershell.aspx 

Hi Moinak,
Kindly please let me know if the token generation which is used for authorization on the new Billing api can be done in Java.
i dont see for Active directory with native client applications there are any samples available over the internet kindly please let me know with any samples for generating the authorization using Java for consuming the new Billing API.

Thanks in Advance,
Athipathy

@Athipathy- Can you try the AD samples here:

https://github.com/AzureAD/azure-activedirectory-library-for-java

@Sirry - there seems to be an extra ' before filter.

this is a valid query: https://management.azure.com/subscriptions/{subscription-Id}/providers/Microsoft.Commerce/RateCard?api-version=2015-06-01-preview&$filter=OfferDurableId eq MS-AZR-0003p and Currency eq USD and Locale eq en-US and RegionInfo eq US
