Warning

On October 30, 2020, the Bing Search APIs moved from Azure AI services to Bing Search Services. This documentation is provided for reference only. For updated documentation, see the Bing search API documentation. For instructions on creating new Azure resources for Bing search, see Create a Bing Search resource through the Azure Marketplace.

The Local Business Search API sends a search query to Bing to get results that include restaurants, hotels, or other local businesses. For places, the query can specify the name of the local business or a category (for example, restaurants near me). Entity results include persons, places, or things. Place in this context is business entities, states, countries/regions, etc.

This section provides technical details about the response objects, and the query parameters and headers that affect the search results. For examples that show how to make requests, see Local Business Search C# quickstart or Local Business Search Java quickstart.

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

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

For information about the JSON objects that the response includes, see Response objects.

For information about permitted use and display of results, see Use and display requirements.

Endpoint

To request local business results, send a GET request to:

https://api.cognitive.microsoft.com/bing/v7.0/localbusinesses/search

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.
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 Azure AI services.
Pragma	Optional request header By default, Bing returns cached content, if available. To prevent Bing from returning cached content, set the Pragma header to no-cache (for example, Pragma: no-cache).
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. Use the client ID for each Bing API request that your app makes for this user on the device. ATTENTION: You must ensure that this Client ID is not linkable to any authenticatable user account information. 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—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—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— 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— 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— The horizontal velocity (speed), in meters per second, that the client device is traveling. alt— The altitude of the client device, in meters. are—Optional. The radius, in meters, that specifies the vertical accuracy of the coordinates. Radius defaults to 50 Kilometers. Specify this key only if you specify the `alt` key. NOTE: Although these keys are optional, the more information that you provide, the more accurate the location results are. NOTE: 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-MSEdge-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 request may include the following query parameters. See the Required column for required parameters. You must URL encode the query parameters.

Name	Value	Type	Required
count	The number of results to return, starting with the index specified by the `offset` parameter.	String	No
localCategories	List of options that define search by business category. See Local Business Categories search	String	No
mkt	The market where the results come from. For a list of possible market values, see Market Codes. NOTE: The Local Business Search API currently only supports en-us market and language.	String	Yes
offset	The index to start results specified by the `count` parameter.	Integer	No
q	The user's search term.	String	No
responseFormat	The media type to use for the response. The following are the possible case-insensitive values. JSON JSONLD The default is JSON. For information about the JSON objects that the response contains, see Response Objects. If you specify JsonLd, the response body includes JSON-LD objects that contain the search results. For information about the JSON-LD, see JSON-LD.	String	No
safeSearch	A filter used to filter adult content. The following are the possible case-insensitive filter values. Off—Return webpages with adult text, images, or videos. Moderate—Return webpages with adult text, but not adult images or videos. Strict—Do not return webpages 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. 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

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.
