Zip Code API
The Zip Code API provides access to resources (data entities) via URI paths. To use a REST API, your application will make an HTTP request and parse the response. By default, the response format is XML. Because the REST API is based on open standards, you can use any web development language to access the API.
Most Comprehensive ZIP Code Data Available: USA 5 digit zip code and Canadian postal code database.
How to use the Zip Code API: With the API, User Authentication is Necessary for every request and hence adding an api key parameter in every request is a must. Another necessary field is country, it's necessary because on the basis of country we can differentiate which database user has sent the request. PageNumber or PostalCode parameter will also be necessary. Page size will be 100 if/where PageNumber parameter will be used.
Country Parameter Abbreviation in URI:
For USA5 database in URI request parameter: country=us5
For Canada database in URI request parameter: country=ca
