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 an API key , you can test out the Single Search service either:

Getting Started

The single search service is available through the following URL:

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

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

Endpoints

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

NameDescriptionData TypeRequired
authTokenProvided API KeyYes
queryString indicating the text to search for
string
Yes
maxResultsLimits search results by the specified number. Must be a value between 1 and 100.
Int
No
currentLonLatThe 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
includeOnlyA comma-separated list of InterpTypes to include in the search response. Allowed filters: Country, State, County, City, POBox, 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.)


To include results from ZIP codes that only apply to post office boxes, the values POBox and Zip must be included in your request.

string
No
poiCategoriesA 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
countriesA comma-separated list of country codes by which you want to filter all results. It defaults to ISO format.
string
No
countryTypeThe standard for country abbreviations: ISO, FIPS, GENC2, and GENC3.
string
No
statesA comma-separated list of state abbreviations by which you want to filter all results.
string
No
includeSet 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
useCustomPlacesIf set to true, returns any custom places in the account where the location’s PlaceId or PlaceName starts with the query string. (Only include name and ID in custom place searches. Search cannot locate custom places by address, including city, state, or ZIP). Custom place results will be included in the result list before any single search results.
boolean
No
separateHNSets whether the house number should be returned as a separate field from the rest of the street address. Default is false.
boolean
No
getAllHNRangesIf set to true, all potential house number ranges will be returned for a particular street match. Default is false.
boolean
No
includeTrimblePlaceIds (North America Only)Set to true to return the TrimblePlaceId, PlaceName and SiteName for a location, if they exist. Default is false.
boolean
No
langThe language to use in results. U.S. English is the default.
string
No
includeCenterUsed with partial postal code queries. When provided, the center coordinates of multiple postal code points will be calculated and returned. For example, a search for &includeOnly=zip&query=840 will return a long list of ZIP codes starting with “840.” Adding &includeCenter instead returns a single point that is roughly central to all of those ZIP codes.
boolean
No
strictMatchLimits the amount of difference that is allowed between the input query and the match results. This is generally better left to the default of false, but in some cases where automation is applied to results, it may limit false positives.
boolean
No
radiusFromCurrentLonLatLimits search results to within a specified distance in miles from the current location, as identified by currentLonLat. A valid currentLonLat must be sent in the request for this parameter to take effect. In some cases, a short radiusFromCurrentLonLat may produce no matches.
float
No

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

NameDescriptionData TypeRequired
matchNamedRoadsOnlyWhen looking up coordinates, this forces reverse geocoding to match named roads only.
boolean
No
maxCleanupMilesWhen looking up coordinates, this sets a maximum radius, in miles, in which to find the closest matching road.
double
No
headingUsed 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

Test the API Now

To test the Search API:

  1. Enter your API KEY in the box below. If you don’t have a key, you can request a free, limited-time trial key .
  2. By default, this test is set to search in North America (NA). You can change the region by replacing NA with one of the other supported regions—Europe (EU), Asia (AS), Africa (AF), South America (SA), and Oceania (OC)—in the GET request URL. (If you are using a trial key in North America, your searches are limited to NA. Outside of North America, trial keys are provided with access to specific regions.)
  3. Use the query parameter to add your location search to the GET request URL. There are several example queries below that demonstrate the correct format.
  4. Add any other optional parameters you would like to enhance your search.
  5. Click GO and the results of your search are shown under Test Response.

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. Only 5-digit ZIP codes are supported in the U.S. (No ZIP+4 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/poiTypes

/search/poiTypes returns POI category names and their associated IDs, which are included in search responses as the POITypeID. 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=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

(For existing implementations only. Not recommended for new customers.)

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.

Sample Request with LocalArea

Available in the U.K., Ireland, and Brazil only

In countries outside of North America, addresses may include a local administrative area—a neighborhood, district, village, or similar—in addition to the city. In the U.K., Ireland, and Brazil, single search can now take into account a local area in order to return fewer and better location matches. It also returns the local area, if available, in the LocalArea field.

Here is an example in the South of England.
