Bad news for all the SEO using Bing API, they are going to stop the FREE API and start charging for it. It is a sad news as Bing API was the only FREE alternative to google scarping. We have used it partially on our SEO software tool to get relevant results for several campaigns.
Here the email from Bing team:
Dear Bing API Developer:
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. Developers will be encouraged to try the Bing Search API for free on the Windows Azure Marketplace during the transition period, 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.
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. 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.

We might be using their service but 40 dollars for 20,000 it seems quite too much at the moment.
