Image Search API v7 reference

The Image Search API lets you send a search query to Bing and get back a list of relevant images. This section provides technical details about the query parameters and headers that you use to request images and the JSON response objects that contain them. For examples that show how to make requests, see Searching the Web for Images.

For information about the headers that requests should include, see Request Headers.

For information about the query parameters that requests should include, see Query Parameters.

For information about the JSON response objects that responses may include, see Response Objects.

For information about permitted use and display of results, see Bing Search API Use and Display requirements.

Endpoints

To request images, send a GET request to one of the following URLs:

Endpoint Description
https://api.cognitive.microsoft.com/bing/v7.0/images/search Returns images that are relevant to the users search query.
https://api.cognitive.microsoft.com/bing/v7.0/images/details Returns insights about an image, such as webpages that include the image.
https://api.cognitive.microsoft.com/bing/v7.0/images/trending Returns images that are trending based on search requests made by others. The images are broken out into different categories. For example, Popular People Searches.

For a list of markets that support trending images, see Trending Images.

The request must use the HTTPS protocol.

Note

The maximum URL length is 2,048 characters. To ensure that your URL length does not exceed the limit, the maximum length of your query parameters should be less than 1,500 characters. If the URL exceeds 2,048 characters, the server returns 404 Not found.

Headers

The following are the headers that a request and response may include.

Header Description
Accept Optional request header.

The default media type is application/json. To specify that the response use JSON-LD, set the Accept header to application/ld+json.
Accept-Language Optional request header.

A comma-delimited list of languages to use for user interface strings. The list is in decreasing order of preference. For more information, including expected format, see RFC2616.

This header and the setLang query parameter are mutually exclusive—do not specify both.

If you set this header, you must also specify the cc query parameter. To determine the market to return results for, Bing uses the first supported language it finds from the list and combines it with the cc parameter value. If the list does not include a supported language, Bing finds the closest language and market that supports the request or it uses an aggregated or default market for the results. To determine the market that Bing used, see the BingAPIs-Market header.

Use this header and the cc query parameter only if you specify multiple languages. Otherwise, use the mkt and setLang query parameters.

A user interface string is a string that's used as a label in a user interface. There are few user interface strings in the JSON response objects. Any links to Bing.com properties in the response objects apply the specified language.
BingAPIs-Market Response header.

The market used by the request. The form is <languageCode>-<countryCode>. For example, en-US.

If you specify a market that is not listed in Market Codes, this value may differ from the market you specified in the mkt query parameter. The same is true if you specify values for cc and Accept-Language that can't be reconciled.
BingAPIs-TraceId Response header.

The ID of the log entry that contains the details of the request. When an error occurs, capture this ID. If you are not able to determine and resolve the issue, include this ID along with the other information that you provide the Support team.
Content-Type Optional request header.

If you set the modules query parameter to RecognizedEntities, you may specify the binary of an image in the body of a POST request. If you specify the image in the body of a POST request, you must specify this header and set its value to multipart/form-data.

The maximum image size is 1 MB.
Ocp-Apim-Subscription-Key Required request header.

The subscription key that you received when you signed up for this service in Cognitive Services.
Pragma Optional request header

By default, Bing returns cached content, if available. To prevent cached content, set the Pragma header to no-cache (for example, Pragma: no-cache).
Retry-After Response header.

The response includes this header if you exceed the number of queries allowed per second (QPS) or per month (QPM). The header contains the number of seconds that you must wait before sending another request.
User-Agent Optional request header.

The user agent originating the request. Bing uses the user agent to provide mobile users with an optimized experience. Although optional, you are encouraged to always specify this header.

The user-agent should be the same string that any commonly used browser sends. For information about user agents, see RFC 2616.

The following are examples of user-agent strings.
  • Windows Phone—Mozilla/5.0 (compatible; MSIE 10.0; Windows Phone 8.0; Trident/6.0; IEMobile/10.0; ARM; Touch; NOKIA; Lumia 822)

  • Android—Mozilla/5.0 (Linux; U; Android 2.3.5; en-us; SCH-I500 Build/GINGERBREAD) AppleWebKit/533.1 (KHTML; like Gecko) Version/4.0 Mobile Safari/533.1

  • iPhone—Mozilla/5.0 (iPhone; CPU iPhone OS 6_1 like Mac OS X) AppleWebKit/536.26 (KHTML; like Gecko) Mobile/10B142 iPhone4;1 BingWeb/3.03.1428.20120423

X-MSEdge-ClientID Optional request and response header.

Bing uses this header to provide users with consistent behavior across Bing API calls. Bing often flights new features and improvements, and it uses the client ID as a key for assigning traffic on different flights. If you do not use the same client ID for a user across multiple requests, then Bing may assign the user to multiple conflicting flights. Being assigned to multiple conflicting flights can lead to an inconsistent user experience. For example, if the second request has a different flight assignment than the first, the experience may be unexpected. Also, Bing can use the client ID to tailor web results to that client ID’s search history, providing a richer experience for the user.

Bing also uses this header to help improve result rankings by analyzing the activity generated by a client ID. The relevance improvements help with better quality of results delivered by Bing APIs and in turn enables higher click-through rates for the API consumer.

IMPORTANT: Although optional, you should consider this header required. Persisting the client ID across multiple requests for the same end user and device combination enables 1) the API consumer to receive a consistent user experience, and 2) higher click-through rates via better quality of results from the Bing APIs.

The following are the basic usage rules that apply to this header.
  • Each user that uses your application on the device must have a unique, Bing generated client ID.

    If you do not include this header in the request, Bing generates an ID and returns it in the X-MSEdge-ClientID response header. The only time that you should NOT include this header in a request is the first time the user uses your app on that device.

  • ATTENTION: You must ensure that this Client ID is not linkable to any authenticatable user account information.

  • Use the client ID for each Bing API request that your app makes for this user on the device.

  • Persist the client ID. To persist the ID in a browser app, use a persistent HTTP cookie to ensure the ID is used across all sessions. Do not use a session cookie. For other apps such as mobile apps, use the device's persistent storage to persist the ID.

    The next time the user uses your app on that device, get the client ID that you persisted.

NOTE: Bing responses may or may not include this header. If the response includes this header, capture the client ID and use it for all subsequent Bing requests for the user on that device.

NOTE: If you include the X-MSEdge-ClientID, you must not include cookies in the request.
X-MSEdge-ClientIP Optional request header.

The IPv4 or IPv6 address of the client device. The IP address is used to discover the user's location. Bing uses the location information to determine safe search behavior.

NOTE: Although optional, you are encouraged to always specify this header and the X-Search-Location header.

Do not obfuscate the address (for example, by changing the last octet to 0). Obfuscating the address results in the location not being anywhere near the device's actual location, which may result in Bing serving erroneous results.
X-Search-Location Optional request header.

A semicolon-delimited list of key/value pairs that describe the client's geographical location. Bing uses the location information to determine safe search behavior and to return relevant local content. Specify the key/value pair as <key>:<value>. The following are the keys that you use to specify the user's location.

  • lat—Required. The latitude of the client's location, in degrees. The latitude must be greater than or equal to -90.0 and less than or equal to +90.0. Negative values indicate southern latitudes and positive values indicate northern latitudes.

  • long—Required. The longitude of the client's location, in degrees. The longitude must be greater than or equal to -180.0 and less than or equal to +180.0. Negative values indicate western longitudes and positive values indicate eastern longitudes.

  • re—Required. The radius, in meters, which specifies the horizontal accuracy of the coordinates. Pass the value returned by the device's location service. Typical values might be 22m for GPS/Wi-Fi, 380m for cell tower triangulation, and 18,000m for reverse IP lookup.

  • ts—Optional. The UTC UNIX timestamp of when the client was at the location. (The UNIX timestamp is the number of seconds since January 1, 1970.)

  • head—Optional. The client's relative heading or direction of travel. Specify the direction of travel as degrees from 0 through 360, counting clockwise relative to true north. Specify this key only if the sp key is nonzero.

  • sp—Optional. The horizontal velocity (speed), in meters per second, that the client device is traveling.

  • alt—Optional. The altitude of the client device, in meters.

  • are—Optional. The radius, in meters, that specifies the vertical accuracy of the coordinates. Specify this key only if you specify the alt key.

NOTE: Although many of the keys are optional, the more information that you provide, the more accurate the location results are.

NOTE: Although optional, you are encouraged to always specify the user's geographical location. Providing the location is especially important if the client's IP address does not accurately reflect the user's physical location (for example, if the client uses VPN). For optimal results, you should include this header and the X-Search-ClientIP header, but at a minimum, you should include this header.

Note

Remember that the Terms of Use require compliance with all applicable laws, including regarding use of these headers. For example, in certain jurisdictions, such as Europe, there are requirements to obtain user consent before placing certain tracking devices on user devices.

Query parameters

The following are the query parameters that a request may include. See the Required column for required parameters. You must URL encode the query parameter values. For information about query parameters that you use to filter the images that Bing returns, see Filter Query Parameters.

Name Value Type Required
cab The bottom coordinate of the region to crop.

The coordinate is a fractional value of the original image's height and is measured from the top, left corner of the image. Specify the coordinate as a value from 0.0 through 1.0.

Use this parameter only with the Insights API. Do not specify this parameter when calling the Images, Trending Images, or Web Search APIs.
Float No
cal The left coordinate of the region to crop.

The coordinate is a fraction of the original image's width and is measured from the top, left corner of the image. Specify the coordinate as a value from 0.0 through 1.0.

Use this parameter only with the Insights API. Do not specify this parameter when calling the Images, Trending Images, or Web Search APIs.
Float No
car The right coordinate of the region to crop.

The coordinate is a fraction of the original image's width and is measured from the top, left corner of the image. Specify the coordinate as a value from 0.0 through 1.0.

Use this parameter only with the Insights API. Do not specify this parameter when calling the Images, Trending Images, or Web Search APIs.
Float No
cat The top coordinate of the region to crop.

The coordinate is a fraction of the original image's height and is measured from the top, left corner of the image. Specify the coordinate as a value from 0.0 through 1.0.

Use this parameter only with the Insights API. Do not specify this parameter when calling the Images, Trending Images, or Web Search APIs.
Float No
ct The crop type to use when cropping the image based on the coordinates specified in the cal, cat, car, and cab parameters.

The following are the possible values.
  • 0—Rectangular (default)

Use this parameter only with the Insights API. Do not specify this parameter when calling the Images, Trending Images, or Web Search APIs.
Unsigned Integer No
cc A 2-character country code of the country where the results come from. For a list of possible values, see Market Codes.

If you set this parameter, you must also specify the Accept-Language header. Bing uses the first supported language it finds in the specified languages and combines it with the country code to determine the market to return results for. If the languages list does not include a supported language, Bing finds the closest language and market that supports the request. Or, Bing may use an aggregated or default market for the results.

Use this query parameter and the Accept-Language header only if you specify multiple languages. Otherwise, you should use the mkt and setLang query parameters.

This parameter and the mkt query parameter are mutually exclusive—do not specify both.
String No
count The number of images to return in the response. The actual number delivered may be less than requested. The default is 35. The maximum value is 150.

You use this parameter along with the offset parameter to page results. For example, if your user interface displays 20 images per page, set count to 20 and offset to 0 to get the first page of results. For each subsequent page, increment offset by 20 (for example, 0, 20, 40).

Use this parameter only with the Image Search API. Do not specify this parameter when calling the Insights, Trending Images, or Web Search APIs.
UnsignedShort No
id An ID that uniquely identifies an image. Use this parameter to ensure that the specified image is the first image in the list of images that Bing returns. The Image object's imageId field contains the ID that you set this parameter to. String No
imgUrl The URL of an image that you want to get insights of. Use this parameter as an alternative to using the insightsToken parameter to specify the image. You may also specify the image by placing the binary of the image in the body of a POST request. If you use the binary option, see the Content-Type header.

The maximum supported image size is 1 MB.

Use this parameter only with the Insights API. Do not specify this parameter when calling the Images, Trending Images, or Web Search APIs.
String No
insightsToken An image token. The Image object's imageInsightsToken contains the token. Specify this parameter to get additional information about an image, such as a caption or shopping source. For a list of the additional information about an image that you can get, see the modules query parameter.

Use this parameter only with the Insights API. Do not specify this parameter when calling the Images, Trending Images, or Web Search APIs.
String No
mkt The market where the results come from. Typically, mkt is the country where the user is making the request from. However, it could be a different country if the user is not located in a country where Bing delivers results. The market must be in the form <language code>-<country code>. For example, en-US. The string is case insensitive. For a list of possible market values, see Market Codes.

NOTE: If known, you are encouraged to always specify the market. Specifying the market helps Bing route the request and return an appropriate and optimal response. If you specify a market that is not listed in Market Codes, Bing uses a best fit market code based on an internal mapping that is subject to change.

This parameter and the cc query parameter are mutually exclusive—do not specify both.
String No
modules A comma-delimited list of insights to request. The following are the possible case-insensitive values.
  • All—Return all insights, if available, except RecognizedEntities.

  • BRQ—Best representative query. The query term that best describes the image.

  • Caption—A caption that provides information about the image. If the caption contains entities, the response may include links to images of those entities.

  • Collections—A list of related images.

  • Recipes—A list of recipes for cooking the food shown in the images.
  • PagesIncluding—A list of webpages that include the image.

  • RecognizedEntities—A list of entities (people) that were recognized in the image.

    NOTE: You may not specify this module with any other module. If you specify it with other modules, the response doesn't include recognized entities.

  • RelatedSearches—A list of related searches made by others.

  • ShoppingSources—A list of merchants where you can buy related offerings.

  • SimilarImages—A list of images that are visually similar to the original image.

  • SimilarProducts—A list of images that contain a product that is similar to a product found in the original image.

  • Tags—Provides characteristics of the type of content found in the image. For example, if the image is of a person, the tags might indicate the person's gender and type of clothes they're wearing.

If you specify a module and there is no data for the module, the response object doesn't include the related field. For example, if you specify Caption and it does not exist, the response doesn't include the imageCaption field.

To include related searches, the request must include the original query string.

Although the original query string is not required for similar images or products, you should always include it because it can help improve relevance and the results.

Use this parameter only with the Insights API. Do not specify this parameter when calling the Images, Trending Images, or Web Search APIs.
String No
offset The zero-based offset that indicates the number of images to skip before returning images. The default is 0. The offset should be less than (totalEstimatedMatches - count).

To page results, use this parameter along with the count parameter. For example, if your user interface displays 20 images per page, set count to 20 and offset to 0 to get the first page of results. For each subsequent page, increment offset by 20 (for example, 0, 20, 40).

It is possible for multiple pages to include some overlap in results. To prevent duplicates, see nextOffset.

Use this parameter only with the Image API. Do not specify this parameter when calling the Trending Images API or the Web Search API.
Unsigned Short No
q The user's search query term. The term cannot be empty.

The term may contain Bing Advanced Operators. For example, to limit images to a specific domain, use the site: operator.

To help improve relevance of an insights query (see insightsToken), you should always include the user's query term.

Use this parameter only with the Image Search API. Do not specify this parameter when calling the Trending Images API.
String Yes
safeSearch Filter images for adult content. The following are the possible filter values.
  • Off—May return images with adult content. If the request is through the Image Search API, the response includes thumbnail images that are clear (non-fuzzy). However, if the request is through the Web Search API, the response includes thumbnail images that are pixelated (fuzzy).

  • Moderate—If the request is through the Image Search API, the response doesn't include images with adult content. If the request is through the Web Search API, the response may include images with adult content (the thumbnail images are pixelated (fuzzy)).

  • Strict—Do not return images with adult content.

The default is Moderate.

NOTE: If the request comes from a market that Bing's adult policy requires that safeSearch is set to Strict, Bing ignores the safeSearch value and uses Strict.

NOTE: If you use the site: query operator, there is the chance that the response may contain adult content regardless of what the safeSearch query parameter is set to. Use site: only if you are aware of the content on the site and your scenario supports the possibility of adult content.
String No
setLang The language to use for user interface strings. Specify the language using the ISO 639-1 2-letter language code. For example, the language code for English is EN. The default is EN (English).

Although optional, you should always specify the language. Typically, you set setLang to the same language specified by mkt unless the user wants the user interface strings displayed in a different language.

This parameter and the Accept-Language header are mutually exclusive—do not specify both.

A user interface string is a string that's used as a label in a user interface. There are few user interface strings in the JSON response objects. Also, any links to Bing.com properties in the response objects apply the specified language.
String No
