Two different meanings of “Bing Search API”

Microsoft’s Bing Search APIs were a product for integrating Bing web, image and other search data. Microsoft announced that the APIs would be retired on August 11, 2025, and directed customers toward Grounding with Bing Search in Azure AI Agents. That service supplies web grounding for AI agents; it is not the same interface as a general-purpose endpoint returning a normalized SERP response. Microsoft’s retirement notice is the primary source. Status checked October 22, 2026.

A Bing SERP API is a separate category: it requests a Bing results page and returns extracted result data. Serqo offers this through its own authenticated search API. It is not Microsoft’s retired service and does not promise drop-in compatibility with it.

Request Bing web results with Serqo

Use engine: "bing" and type: "web" on the shared search endpoint.

curl https://api.serqo.io/v1/search \
  -H "x-api-key: $SERP_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"q":"privacy focused search","engine":"bing","type":"web","gl":"us","hl":"en"}'

Read result items from data.results. Common fields include position, title, url, source and snippet; values depend on what the results page provides. See the Bing Search API reference for accepted parameters and response details.

What the request controls

q is the search phrase. gl sets the market country and hl the interface language. Bing currently supports desktop profiles only in Serqo; mobile device profiles are available for Google only. Unsupported parameters such as Google’s tbs time filter should be omitted for Bing.

Choose the right Microsoft product

If you need arbitrary public Bing results in a JSON response, use a SERP results provider and check its current engine support. If you need to measure a site you own in Bing, the Bing Webmaster API serves a different purpose: it exposes site, crawl, keyword and search performance data for registered sites. If your product needs an LLM to ground answers in live web data, review Microsoft’s current Grounding with Bing Search documentation and requirements.

Frequently asked questions

Can I still create a Microsoft Bing Search API subscription?

No. Microsoft’s retirement notice says the Bing Search APIs were retired on August 11, 2025. Grounding with Bing Search is a distinct Azure AI capability.

Does Serqo replace the old Microsoft API?

No. Serqo has its own request format, fields, authentication and supported search types. It returns Bing SERP data through /v1/search; applications must adapt to that contract.

Can I use the Bing Webmaster API for competitor keywords?

The Bing Webmaster API is for information about sites registered to your account, such as search and indexing performance. It is not an endpoint for retrieving arbitrary public Bing results pages.
