Handle the image search response
When you send a request to Image Search API, it returns an ImageAnswer object in the response body. The object may include one or more of the following fields:
JSON
{
"_type": "Images",
"readLink": "images/search?q=black cocktail dresses",
"webSearchUrl": "https://www.bing.com/images/search?q=black cocktail dresses&FORM=OIIARP",
"queryContext": { ... },
"totalEstimatedMatches": 835,
"nextOffset": 36,
"currentOffset": 0,
"value": [ { ... } ],
"queryExpansions": [ { ... } ],
"pivotSuggestions": [ { ... } ],
"relatedSearches": [ { ... } ]
}
But if an error occurs, the response body contains an ErrorResponse object. Bing returns an error response for all 400 level HTTP status codes. Read more.
JSON
{
"_type": "ErrorResponse",
"errors": [
{
"code": "InvalidAuthorization",
"subCode": "AuthorizationMissing",
"message": "Authorization is required.",
"moreDetails": "Subscription key is not recognized."
}
]
}
For information about the nextOffset and totalEstimatedMatches fields, see Paging image and video results.
Anteckning
- Images must be displayed in the order provided in the response.
- Because URL formats and parameters are subject to change without notice, use all URLs as-is. You should not take dependencies on the URL format or parameters except where noted.
The value field contains the list of Image objects that Bing thought were relevant. Here's what the Image object looks like in the response.

If you plan to display a collage of the thumbnails on a page, use the following fields:
thumbnailUrl— A URL to the thumbnail of the image thatcontentUrlpoints to.thumbnail— The size of the thumbnail thatthumbnailUrlpoints to.
For information about resizing the thumbnail, see Resizing and cropping thumbnails.
When the user hovers over the thumbnail, you should display the size of the original image (see the width and height fields), the encoding format (see the encodingFormat field), and the domain of the publisher (parse the domain from the URL in the hostPageUrl field).
If the user clicks on the thumbnail, you could:
- Use the URL in
webSearchUrlto take the user to Bing where they can discover more information about the image. - Use the token in the
imageInsightsTokenfield to call Visual Search API to display insights about the image yourself. - Use the URL in
hostPageUrlto take the user to the publisher's webpage where Bing found the image.
Regardless, at some level, you should give the user the option of visiting the webpage where Bing found the image.
Each image includes an insights token (see the imageInsightsToken field) that you can use to get information about the image, such as a collection of related images, web pages that include the image, or a list of merchants where you can buy the product shown in the image. For information about how to get insights, see Visual Search API.
Each image includes an insightsMetadata field, which contains a count of the number of websites where you can shop or perform other actions related to the image. For example, if the image shows an apple pie, the metadata includes a count of the number of websites where you can buy an apple pie. To indicate the number of offers in your UX, include badging such as a shopping cart icon that contains the count. When the user clicks on the icon, use the token in imageInisghtsToken to get the list of websites from Visual Search API.
The following list identifies the types of metadata counts that an image may include.
recipeSourcesCount— The number of webpages that include recipes of the food shown in the image.pagesIncludingCount— The number of webpages that include the image.availableSizesCount— The number of different sizes (width/height) of the image that Bing found.shoppingSourcesCount— The number of websites that sell the products seen in the image.
Most responses include the queryExpansions field, which contains a list of queries that expand the user’s query string in an effort to narrow the search results. This may help the user focus more on the content that they’re really interested in. For example, the query that returned the following response fragment was black cocktail dress*. Here's the list of expanded queries that Bing returned (the bolded words are the ones that Bing added):
- Black Lace Cocktail Dress
- Little Black Cocktail Dress
- Black Halter Cocktail Dress
JSON
"queryExpansions": [
{
"text": "Black Lace Cocktail Dress",
"displayText": "Lace",
"webSearchUrl": "https://www.bing.com/images/search?q=Black+Lace+Cocktail...",
"searchLink": "https://api.bing.microsoft.com/v7/images/search?q=Black+Lace+Cocktail...",
"thumbnail": {
"thumbnailUrl": "https://tse4.mm.bing.net/th?q=Black+Lace+Cocktail+Dress&pid=Api..."
}
},
{
"text": "Little Black Cocktail Dress",
"displayText": "Little",
"webSearchUrl": "https://www.bing.com/images/search?q=Little+Black+Cocktail+Dress...",
"searchLink": "https://api.bing.microsoft.com/v7/images/search?q=Little+Black...",
"thumbnail": {
"thumbnailUrl": "https://tse3.mm.bing.net/th?q=Little+Black+Cocktail+Dress&pid=Api..."
}
},
{
"text": "Black Halter Cocktail Dress",
"displayText": "Halter",
"webSearchUrl": "https://www.bing.com/images/search?q=Black+Halter+Cocktail+Dress...",
"searchLink": "https://api.bing.microsoft.com/v7/images/search?q=Black+Halter...",
"thumbnail": {
"thumbnailUrl": "https://tse1.mm.bing.net/th?q=Black+Halter+Cocktail+Dress&pid=Api..."
}
},
The queryExpansions field contains a list of Query objects. The text field contains the expanded query that you display in your UX (the displayText field contains the expansion term). Make text clickable by using the URL in webSearchUrl or searchLink. Use webSearchUrl to send the user to Bing's Image search results. If you provide your own results page experience, use searchLink to get new image search results using the expanded query string.
If Bing can segment the user’s query, the response includes the pivotSuggestions field, which is a list of Pivot objects. Each Pivot object contains one of the segments from the user’s query (see the pivot field). For example, if the user's query is black cocktail dresses, the pivots are black, cocktail, and dress. Basically, Bing replaces each pivot word in the user's query with another term. The following list contains some of the query suggestions for the black pivot.
- Short Cocktail Dresses
- Red Cocktail Dresses
- Vintage Cocktail Dresses
JSON
"pivotSuggestions": [
{
"pivot": "black",
"suggestions": [
{
"text": "Short Cocktail Dresses",
"displayText": "Short",

The pivotSuggestions field contains the list of segments (pivots) that the original query was broken into. For each pivot, the response contains a list of Query objects that contain suggested queries. The text field contains the suggested query. The displayText field contains the term that replaces the pivot in the original query.
Make text clickable by using the URL in webSearchUrl or searchLink. Use webSearchUrl to send the user to Bing's Image search results. If you provide your own results page experience, use searchLink to get new image search results using the pivot query string.
The relatedSearches field contains a list of the most popular related queries made by other users. Each query in the list includes a query string (text), a query string with hit highlighting characters (displayText), and a URL (webSearchUrl) to Bing's Image search results page for that query.
JSON
"relatedSearches": [
{
"text": "Sail Dinghy",
"displayText": "Sail Dinghy",
"webSearchUrl": "https://www.bing.com/images/search?q=Sail+Dinghy&FORM=IRPATC",
"searchLink": "https://api.bing.microsoft.com/v7/images/search?q=Sail+Dinghy",
"thumbnail": {
"thumbnailUrl": "https://tse3.mm.bing.net/th?q=Sail+Dinghy&pid=Api"
}
},
. . .
]
Use the displayText query string and the webSearchUrl URL to create a hyperlink that takes the user to Bing's Image search results page for the related query. If you provide your own results page experience, use searchLink to get new image search results using the related query string.
