Single Search API

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).

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

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
2. You will need a valid API key to replace {your-api-key}
3. Replace {endpoint} with one of the endpoints below
