Microsoft has announced that it will discontinue its public Bing Search API services, encompassing Search v7 and Custom Search, effective August 11, 2025. This alteration will impact all users, with existing resources being deactivated and new user registrations being prohibited from that date. To mitigate this transition, Microsoft advises developers to shift to the "Grounding with Bing Search" feature within the Azure AI Agent Service, adapting to the novel service architecture and associated cost structure. Furthermore, Microsoft urges developers to evaluate the compliance of their data processing practices and to promptly review API usage to identify affected resources, ensuring a seamless transition. This modification marks a strategic shift in Microsoft's AI offerings, necessitating close attention and appropriate adjustments from developers.
