Postcode Anywhere is an information-as-a-service provider offering over 250 separate web services covering a broad range of business efficiency tools for address and data capture, validation and cleansing to geo-coding, mapping, and route planning and optimization.
The Store Finder API can be used to let developers provide customers with the location of the nearest store. The API geocodes the postcodes of all of a site owner's stores, geocodes a site visitor's location and presents a list of the nearest stores.
The API uses a number of protocols including REST, SOAP and XML-RPC. Responses can be formatted in XML, JSON, CSV, HTML and PDF.
