Gearing up for API changes

For the past several years, the Bing Search API has made search data available for developers to innovate and build upon. Today we are announcing that the Bing Search API will transition to an offering made available on the Windows Azure Marketplace. The Windows Azure Marketplace is a one stop shop for cloud data, apps, and services, including the Microsoft Translator API. Through this platform, developers can access hundreds of data sets and APIs and distribute their applications through the marketplace. 

A few important things to note regarding the upcoming transition:

  • With the transition, Bing Search API developers will have access to fresher results, improved relevancy, and more opportunities to monetize their usage of the Search API. To offer these services at scale, we plan to move to a monthly subscription model. Developers can expect subscription pricing to start at approximately $40 (USD) per month for up to 20,000 queries each month.
  • The transition will begin in several weeks and will take a few months to complete. During the transition period, developers will be encouraged to try the Bing Search API for free on the Windows Azure Marketplace, before we begin charging for the service.
  • At this time, you can continue using Bing Search API 2.0 free of charge. After the transition period, Bing Search API 2.0 will no longer be available for free public use, and instead developers can continue accessing the API on the Windows Azure Marketplace.

Details regarding the transition timeline, pricing structure, and other changes will be announced in upcoming weeks. In the meantime, we encourage you to explore the Windows Azure Marketplace and read the documentation on accessing data sets and APIs. As a Bing Search API developer, you can expect the transition to involve targeting a new API end point, moderate changes to the request and response schemas, and a new security requirement to authenticate your application key. Developers using approximately 3 to 4 million queries and above can expect to transition through a separate process (details will be provided shortly). 


We understand that many of you are using the API as an important element in your websites and applications, and we will continue to share details with you through the Bing Developer Blog as we approach the transition. We appreciate your patience during this time.

  • So those of us using the search API on small scale apps still have to fork out $40pm or watch them fall over in a heap with ridiculous short notice. Should have stuck with Google thanks a lot Bing.

  • It's been only a few minutes and there are already multiple negative comments on Twitter thanks to this announcement. I'm very disappointed, because I wanted to create non-profit startup organization using Bing Search API. Sad day.

  • Thanks for the feedback. We are absolutely thinking about ways to enable smaller scale applications to keep experimenting with the API. Please stay tuned for more details over the next several weeks.

  • Please, Bing Team, I'm begging you to make allowance for non-profits. We're a library who uses both the Search API and the Translation API on our site as services for our patrons, and each page that these reside on gets less than 1000 & 200 hits/views, respectively. The cost for our paltry usage really can't be justified for us, and I'll be forced to try to find other free services (though the translation will probably just cease to be available on our site). It would be really great if you could allow institutions like ours to continue to use these for free.

    Thanks for listening...

  • Yes please make it free to use for non-profits! Please!!

  • From free to $40.00 a month to use the Bing Search  API; really!!!

    This will definitely not fly with most devs.

    The API usage will fall to nearly zero very quickly.

  • As you make this transition, I would anticipate most developers abandoning Bing search for one of the many free services available. As a small time WP7 app developer I cannot and will not spend $40/month to get search results. I do not expect my voice will matter, but expect one less developer to be using and promoting bing, probably many more to follow unless a free option is made available. This is a shame sense Microsoft needs the developer community to use and promote its tools before the average user will even notice. WP7 is a perfect example and is based entirely around bing. Removing the ability for developers to use bing will splinter the WP7 apps and force developers to use your competitors tools instead.

    Hoping someone will consider these concerns,

    Loyal .Net / WP7 developer

    But where is the loyality from Bing?

  • I think, this decision is a different way of reducing the Bing API workload. If you want closing this service, can you say directly.

    No longer need to evaluate alternatives.

    Thanks for genius ideas. I will always remember Bing values is $40.

  • @The Bing Team:

    My application uses high volumes of the Bing API. We currently have about 700,000 queries a day. How much will we have to pay in future? What will be the cost of 1,000 search queries?

    I hope you understand that you are putting many businesses at risk with that step. Please at least provide some more details!?

  • *PLEASE* do this to bing maps too. I need to use it on a commercial plan but the license price is absurd... pay as I go is the right and just way to do it. Today i am studying move to OpenStreetMaps, creating and mantaining my own tile server. I would gladly pay for bing maps (I need Silverlight integration) if the price was something realistic (to a startup). Any chance this would happen?

  • Okay, seriously.  You just pushed a bunch of people over to Google.  Microsoft.  Seriously.  You need to think things out before you make a decision.  How is this going to benefit the hobbiest and mobile app developers?  You need to have a free tier and a pay as you go model.  Please change this before too many people move to Google.

  • Hello, I have successfully coded my application and using Bing API with having "powered by Bing" text on it with good respect. But if you make $40 price, I can't afford that and I would have to close my application, so please...

    My suggestion is to make api price to only developers who use high number of requests, thanks!

  • This has got to be the most bungled plan and notification ever.  Not only are you going to start charging which is fune, but you're also changing the API endpoints so that people have to go back and re-code their applications just so they keep working?  You could atleast keep the same endpoints working and display ads in the results or something.  This is typical of Microsoft really, release some web service, then a year or two later after its gained a modest adoption level you rip it out and decide its obsolete.

  • Thanks for the feedback. We recognize the need for developers to keep experimenting with the Bing Search API. Our team is actively exploring potential ways to enable this kind of experimentation.

  • This is very sad news. I moved from Google to Bing API, because you offer unlimited query (1IP/7 connection)

    for free. And now, you're going to make API change from a free.

    I want to think about this: WHY would you charge ONLY a deloper who make a lot of queries!?

    Before I move to Google again... please reconsider about this.

    I don't want to pay $40/m because my website is NO ADVERTISEMENT or donations.

    Please, help non-profit people :(
