News Search API v7 reference

Warning

Bing Search APIs are moving from Cognitive Services to Bing Search Services. Starting October 30, 2020, any new instances of Bing Search need to be provisioned following the process documented here. Bing Search APIs provisioned using Cognitive Services will be supported for the next three years or until the end of your Enterprise Agreement, whichever happens first. For migration instructions, see Bing Search Services.

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

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 objects that the response may include, see Response Objects.

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

Note

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.

Endpoints

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

URL	Description
https://api.cognitive.microsoft.com/bing/v7.0/news	Returns the top news articles by category. For example, you can request the top sports or entertainment articles. For information about specifying categories, see the category query parameter.
https://api.cognitive.microsoft.com/bing/v7.0/news/search	Returns news articles based on the user's search query. If the search query is empty, the call returns the top news articles.
https://api.cognitive.microsoft.com/bing/v7.0/news/trendingtopics	Returns trending news topics that are currently trending on social networks. NOTE: Available only in the en-US and zh-CN markets.

For multi-service subscriptions, you must include the region in the URL. For example: westus.api.cognitive.microsoft.com. See Supported Regions.

The request must use the HTTPS protocol; HTTP is not supported.

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.
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 PC—Mozilla/5.0 (Windows NT 6.3; WOW64; Trident/7.0; Touch; rv:11.0) like Gecko iPad—Mozilla/5.0 (iPad; CPU OS 7_0 like Mac OS X) AppleWebKit/537.51.1 (KHTML, like Gecko) Version/7.0 Mobile/11A465 Safari/9537.53
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. disp—Optional. The user's geographic location in the form, disp:<City, State>. For example, disp:Seattle, Washington. This is the display text version of the user's location that you specified using the lat/long keys. If this value conflicts with the lat/long coordinates, Bing uses the disp value as the user's location. NOTE: Bing ignores this header if the query includes a location. For example, if this header reflects the user's location as San Francisco, but the query is restaurants seattle, Bing returns restaurants located in Seattle, Washington. 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 the request may include. The Required column indicates whether you must specify the parameter. You must URL encode the query parameter values.

Name	Value	Type	Required
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
category	The category of articles to return. For example, Sports articles or Entertainment articles. For a list of possible categories, see News Categories by Market. Use this parameter only with news category requests (see the /news endpoint). If you do not specify this parameter, the response includes both: Headline articles typically published in the last 24 hours from any category, but some articles may be older. If the article is a headline, the article's headline field is set to true. By default, the response includes up to 12 headline articles and clusters. To specify the number of headline articles to return, set the headlineCount query parameter. Articles from each parent category (up to four articles and clusters from each category). If you do not specify headlineCount and the market supports eight categories, the response includes up to 44 articles and clusters (12 headline articles and clusters plus 32 category-specific articles and clusters). Because a cluster contains more than one article, the number of articles in this example, 44, could be more. For example, the response may include 11 headline articles and one cluster, which contains four related headline articles for a total of 15 headline articles.	String	No
count	The number of news articles to return in the response. The actual number delivered may be less than requested. The default is 10 and the maximum value is 100. For trending topics, the default is all trending news topics (approximately 55 articles). You may use this parameter along with the offset parameter to page results. For example, if your user interface displays 20 articles 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. NOTE: Clusters are counted as a single item. For example, if you set the count to 10, the response may include 9 articles and 1 cluster but the cluster may contain 5 articles. NOTE: If you're requesting news categories, specify this parameter only if you specify the category parameter. If you do not specify the category parameter, Bing ignores this parameter.	UnsignedShort	No
freshness	Filter news articles by the following age values: Day—Return news articles that Bing discovered within the last 24 hours Week—Return news articles that Bing discovered within the last 7 days Month—Return news articles that Bing discovered within the last 30 days	String	No
headlineCount	The number of headline articles and clusters to return. The default is 12. Specify this parameter only if you do not specify the category parameter. If you specify the category parameter, Bing ignores this parameter. Use this parameter only with news category requests.	UnsignedShort	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
offset	The zero-based offset that indicates the number of news articles to skip before returning articles. The default is 0. The offset should be less than (totalEstimatedMatches - count). Use this parameter along with the count parameter to page results. For example, if your user interface displays 20 articles 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. NOTE: Clusters are counted as a single item. For example, if you set the count to 10, the response may include 9 articles and 1 cluster but the cluster may contain 5 articles. NOTE: If requesting news categories, specify this parameter only if you specify the category parameter. If you do not specify the category parameter, Bing ignores this parameter.	Unsigned Short	No
originalImg	A Boolean value that determines whether the image's contentUrl contains a URL that points to a thumbnail of the original article's image or the image itself. If the article includes an image, and this parameter is set to true, the image's contentUrl property contains a URL that you may use to download the original image from the publisher's website. Otherwise, if this parameter is false, the image's contentUrl and thumbnailUrl URLs both point to the same thumbnail image. The default is false. Use this parameter only with the News Search API. Do not specify this parameter when calling the Web Search API. Trending Topics ignores this parameter.	Boolean	No
q	The user's search query term. If the term is empty (for example, q=), the response includes the top news stories. The term string may contain Bing Advanced Operators. For example, to limit news to a specific domain, use the site: operator. If you're getting news articles by category, do not include this parameter. Trending Topics ignores this parameter.	String	Yes
safeSearch	Filter news articles for adult content. The following are the possible filter values. Off—Return news articles with adult text, images, or videos. Moderate—Return news articles with adult text but not adult images or videos. Strict—Do not return news articles with adult text, images, or videos. 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.	String	No
setLang	The language to use for user interface strings. You may specify the language using either a 2-letter or 4-letter code. Using 4-letter codes is preferred. For a list of supported language codes, see Bing supported languages. Bing loads the localized strings if setlang contains a valid 2-letter neutral culture code (fr) or a valid 4-letter specific culture code (fr-ca). For example, for fr-ca, Bing loads the fr neutral culture code strings. If setlang is not valid (for example, zh) or Bing doesn't support the language (for example, af, af-na), Bing defaults to en (English). To specify the 2-letter code, set this parameter to an ISO 639-1 language code. To specify the 4-letter code, use the form <language>-<country/region> where <language> is an ISO 639-1 language code (neutral culture) and <country/region> is an ISO 3166 country/region (specific culture) code. For example, use en-US for United States 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
since	The Unix epoch time (Unix timestamp) that Bing uses to select the trending topics. Bing returns trending topics that it discovered on or after the specified date and time, not the date the topic was published. To use this parameter, also specify the sortBy parameter.	Integer	No
sortBy	The order to return the trending topics in. The following are the possible case-insensitive values. Date—Returns trending topics sorted by date from the most recent to the oldest If you do not specify this parameter, there is no specific ordering. However, topic freshness, category, global user engagement, and personalized features are taken into account.	String	No
textDecorations	A Boolean value that determines whether display strings should contain decoration markers such as hit highlighting characters. If true, the strings may include markers. The default is false. To specify whether to use Unicode characters or HTML tags as the markers, see the textFormat query parameter. For information about hit highlighting, see Hit Highlighting.	Boolean	No
textFormat	The type of markers to use for text decorations (see the textDecorations query parameter). The following are the possible values. Raw—Use Unicode characters to mark content that needs special formatting. The Unicode characters are in the range E000 through E019. For example, Bing uses E000 and E001 to mark the beginning and end of query terms for hit highlighting. HTML—Use HTML tags to mark content that needs special formatting. For example, use <b> tags to highlight query terms in display strings. The default is Raw. For a list of markers, see Hit Highlighting. For display strings that contain escapable HTML characters such as <, >, and &, if textFormat is set to HTML, Bing escapes the characters as appropriate (for example, < is escaped to &lt;). For information about processing strings with embedded Unicode characters, see Hit Highlighting.	String	No

Response objects

Note

To comply with the new EU Copyright Directive in France, the Bing Web, News, Video, Image and all Custom Search APIs must omit some content from certain EU News sources for French users. The removed content may include thumbnail images and videos, video previews, and snippets which accompany search results from these sources. As a consequence, the Bing APIs may serve fewer results with thumbnail images and videos, video previews, and snippets to French users.

The following are the JSON objects that the response may include. If the request succeeds, the top-level object in the response is the News object if the endpoint is /news/search or /news, and TrendingTopicAnswer if the endpoint is /news/trendingtopics.

403	The user is authenticated (for example, they used a valid subscription key) but they don’t have permission to the requested resource. Bing may also return this status if the caller exceeded their queries per month quota.
410	The request used HTTP instead of the HTTPS protocol. HTTPS is the only supported protocol.
429	The caller exceeded their queries per second quota.
500	Unexpected server error.

If the request fails, the response contains an ErrorResponse object, which contains a list of Error objects that describe what caused of error. If the error is related to a parameter, the parameter field identifies the parameter that is the issue. And if the error is related to a parameter value, the value field identifies the value that is not valid.

The following are the possible error code and sub-error code values.

Code	SubCode	Description
ServerError	UnexpectedError ResourceError NotImplemented	HTTP status code is 500.
InvalidRequest	ParameterMissing ParameterInvalidValue HttpNotAllowed Blocked	Bing returns InvalidRequest whenever any part of the request is not valid. For example, a required parameter is missing or a parameter value is not valid. If the error is ParameterMissing or ParameterInvalidValue, the HTTP status code is 400. If you use the HTTP protocol instead of HTTPS, Bing returns HttpNotAllowed, and the HTTP status code is 410.
RateLimitExceeded	No sub-codes	Bing returns RateLimitExceeded whenever you exceed your queries per second (QPS) or queries per month (QPM) quota. If you exceed QPS, Bing returns HTTP status code 429, and if you exceed QPM, Bing returns 403.
InvalidAuthorization	AuthorizationMissing AuthorizationRedundancy	Bing returns InvalidAuthorization when Bing cannot authenticate the caller. For example, the Ocp-Apim-Subscription-Key header is missing or the subscription key is not valid. Redundancy occurs if you specify more than one authentication method. If the error is InvalidAuthorization, the HTTP status code is 401.
InsufficientAuthorization	AuthorizationDisabled AuthorizationExpired	Bing returns InsufficientAuthorization when the caller does not have permissions to access the resource. This can occur if the subscription key has been disabled or has expired. If the error is InsufficientAuthorization, the HTTP status code is 403.
