Single Search Geocoding API

Contents

Our Single Search service allows you to geocode an address that a user submits as a single string of text—similar to a query on a web search engine. It returns an array of locations that match the search text. It can also help provide more relevant search results, giving you the ability to search based on the current location (a longitude/latitude point).

Single Search is our most advanced API for geocoding. It allows you to search for addresses, coordinates, places, and points of interest throughout the world. We recommended it for all new implementations.

We also offer a suite of Geocoding APIs that separately supports forward, reverse, and batch geocoding. These APIs provide similar results as Search, but require a more structured input. They are intended for special cases where the customer requirements and user input are more narrowly defined.

With your API key, you can test out the Single Search service.

Getting Started

The single search service is available through the following URL:

https://singlesearch.alk.com/{region}/api/{endpoint}?authToken={your-api-key}

In order to get a valid URL to the single search service, replace {region} above with one of the supported regions: NA, WW, EU
You will need a valid API key to replace {your-api-key}
Replace {endpoint} with one of the endpoints below

Endpoints

GET /search

/search is the main geocoding URL and supports the parameters below.

Name	Description	Data Type	Required
`authToken`	Provided API Key		Yes
`query`	String indicating the text to search for	string	Yes
`maxResults`	Limits search results by the specified number. Must be a value between 1 and 100.	Int	No
`currentLonLat`	The current longitude and latitude, where longitude and latitude are either decimal or integer coordinates.	Complex	No
`excludeResultsFor` Replaces `excludedSearchTypes`, which has been deprecated	A comma-separated list of InterpTypes to exclude from the search. Available types: Country, State, County, City, ZIP, SPLC, Street, RouteNumber, RouteAlpha, POI, POIStreet, FullPostCode, POIType, CrossStreet, LatLon, and CustomPlace.	string	No
`includeOnly`	A comma-separated list of InterpTypes to include in the search response. Allowed filters: Country, State, County, City, Zip, SPLC, Street, RouteNumber, RouteAlpha, POI, POIStreet, FullPostCode, POIType, CrossStreet, LatLon, CustomPlace, and None. (Example: includeOnly=CustomPlace,Street. This will return only custom places and streets that match with the search string.)	string	No
`poiCategories`	A comma-separated list of Points of Interest (POI) category names by which you want to filter all POI results. A GET call to /search/poiCategories can be used to retrieve the current list of categories available for filtering.	string	No
`countries`	A comma-separated list of country codes by which you want to filter all results. It defaults to ISO format.	string	No
`countryType`	The standard for country abbreviations: ISO, FIPS, GENC2, and GENC3.	string	No
`states`	A comma-separated list of state abbreviations by which you want to filter all results.	string	No
`include`	Set to `include=Meta` to include additional metadata in your results, such as road grid and link information as well as the confidence level of the search results. (See `QueryConfidence` in response parameters below.)	string	No
`useCustomPlaces`	If set to true, returns any custom places in the account where the location’s PlaceId or PlaceName starts with the query string. Those results will be included in the result list before any single search results.	boolean	No
`separateHN`	Sets whether the house number should be returned as a separate field from the rest of the street address. Default is false.	boolean	No
`getAllHNRanges`	If set to true, all potential house number ranges will be returned for a particular street match. Default is false.	boolean	No
`includeTrimblePlaceIds`	Set to true to return the `TrimblePlaceId`, `PlaceName` and `SiteName` for a location, if they exist. Default is false.	boolean	No
`lang`	The language to use in results. en-us - U.S. English (Default) en-gb - Great Britain English de - German fr - French es - Spanish it - Italian	string	No

These additional parameters below are only applicable when performing a reverse geocode search using latitude/longitude coordinates.

Name	Description	Data Type	Required
`matchNamedRoadsOnly`	When looking up coordinates, this forces reverse geocoding to match named roads only.	boolean	No
`maxCleanupMiles`	When looking up coordinates, this sets a maximum radius, in miles, in which to find the closest matching road.	double	No
`heading`	Used to determine which road link to snap to. For instance, when crossing a highway. Values are: 0 - North 90 - East 180 - South 270 - East	double	No

Ways to Improve Search Speed and Results

The Search service aims to return at least 90 percent of responses in less than 200 milliseconds, with the majority of responses in 31 milliseconds or less. The response speed of any particular query can vary depending on your input and other factors. Please follow the tips below to ensure you get the fastest possible response times:

Search queries that contain ZIP or postal codes narrow the search and generally perform better than those without postal codes.
Queries with a comma between street address, city, county, state, country, and postal code improve performance and may improve the accuracy of results.
Queries with accurate spellings and complete addresses generally perform better than those where the service has to fill in or correct details.
Queries with extraneous information like parking instructions or phone numbers generally take longer to process.
If you have structured data, using our field labels can speed up your search.
Transmission time may vary depending on your internet connection and location.

GET /search/types

/search/types returns the list of search’s known InterpTypes (See list above under includeOnly parameter). These are independent of the region.

GET /search/poiCategories

/search/poiCategories returns the list of search’s acceptable POI categories for filtering. These are dependent on the region.

GET /search/countries

/search/countries returns the list of search’s acceptable countries for filtering. These are dependent on the region.

GET /search/states

/search/states returns the list of search’s acceptable states for filtering. These are dependent on the region.

Example Queries

/search?query=1 independence way, princeton, nj, 08540&countries=US&states=NJ, NM
/search?query=123&maxResults=101
/search?query=1&currentLonLat=-74.600291,40.360869
/search?query=1 independence way, princeton, nj, 08540&currentLonLat=-74600291,40360869
/search?query=1 independence way, princeton, nj, 08540&excludeResultsFor=POI,POItype
/search?query=1 independence way, princeton, nj, 08540&poiCategories=Airport, bank, CAT scales
/search?query=1 independence way, princeton, nj, 08540&countries=US
/search?query=1 independence way, princeton, nj, 08540&countries=US&countryType=ISO
/search?query=1 independence way, princeton, nj, 08540&states=NJ
/search?query=40.3559242765905,-74.451975067144&includeTrimblePlaceIds=true

Fielded Search

You can also use keywords within a search string to help narrow your results. The keywords available are: housenumber (or hn), route (or rt), street, county, city, zip, splc, fullpostcode, fpc, poi, state, and country.

Example

/search?query=49 Easton Ave New Brunswick state:NJ

Adding the keyword “state” forces “NJ” to be interpreted as a state, and it ensures no other term in the string can be interpreted as a state.

By adding quotation marks, multiple search terms can be grouped together with a keyword.

Example

/search?query=49 street:"Easton Ave" New Brunswick state:NJ

This forces “Easton Ave” to be the only street match.
