Bing Search results and AI summary API (BING_SEARCH) - querying.ai

BING_SEARCH loads the bing.com results page for a query and returns its organic results, ads and related searches, with the AI summary Bing renders above them as aioverview. No account or login is involved.


`taskType`	`BING_SEARCH` (aliases `BING`, `BING_COPILOT_SEARCH`)
Input	`query` or `prompt` (required), up to 4,000 characters; `country`, `include`
Credits	1 per task
Country	Defaults to `US`. Any ISO 3166-1 alpha-2 code.
Location	Not supported (`422 LOCATION_UNSUPPORTED`).

  -d '{ "taskType": "BING_SEARCH", "payload": { "query": "how does a heat pump work in cold weather", "country": "US", "include": { "markdown": true } } }'

Parameters

Field	Required	Description

Response

For example:

{
  "surface": "bing_search",
  "organicResults": [
    { "position": 1, "title": "...", "link": "https://...", "displayedLink": "...", "snippet": "...", "date": "Aug 3, 2026", "page": 1 }
  ],
  "ads": [{ "position": 1, "title": "...", "link": "https://...", "displayedLink": "...", "description": "...", "blockPosition": "top" }],
  "relatedSearches": [{ "query": "...", "link": "https://www.bing.com/search?q=..." }],
  "aioverview": {
    "text": "Heat pumps move heat instead of generating it [1]. ...",
    "sources": [{ "position": 1, "url": "https://...", "label": "..." }],
    "citationPills": [{ "citationPillId": 1, "position": 1, "url": "https://...", "label": "...", "domain": "example.com" }],
    "markdown": "..."
  },
  "text": "Heat pumps move heat instead of generating it [1]. ...",
  "sources": [{ "position": 1, "url": "https://...", "label": "..." }]
}

Field	Description
`surface`	Always `bing_search`.
`organicResults`	The organic results on the page.
`ads`	Ads, omitted when the page has none.
`relatedSearches`	Related searches, omitted when the page has none.
`aioverview`	Bing’s AI summary, or `null` when Bing showed none.
`aioverview.text`	The summary. `[n]` refers to `aioverview.sources[n-1]`.
`aioverview.sources`	The pages the summary cites.
`aioverview.citationPills`	One entry per source behind an inline citation; sources cited together share a `citationPillId`. Omitted when the summary has no inline citations.
`aioverview.markdown`	With `include.markdown: true`.
`rawContent`	The results page HTML, with `include.rawResponse: true`.
`text`, `sources`	Deprecated copies of `aioverview.text` and `aioverview.sources`, empty when there is no summary. Read `aioverview` in new code.

aioverview: null means Bing showed no AI summary for that query. It is not an error, and the results around it are still returned.

Limits and errors

A query (or prompt) longer than 4,000 characters returns 422 VALIDATION_ERROR.
Bing does not write a summary for every query; search-style questions get one more often than instructions. When it shows a summary, Bing moves part of the organic results to the next page, so organicResults is shorter on those pages.
Other request errors are listed in Errors.
