Instant, Free Access to AccuWeather APIs for Developers
Register at developer.accuweather.com and get limited free access to a sampling of AccuWeather API endpoints, including Locations, Current Conditions, and Daily and Hourly Forecasts.
Note: Access to the AccuWeather APIs available through developer.accuweather.com is separate from access to our Enterprise APIs that are described on this page. Free demo keys obtained at developer.accuweather.com will not work on links shown on this documentation site (apidev.accuweather.com/developers/). Thank you for your interest as we continue to expand the role of our new developer site, and thank you for choosing AccuWeather APIs!
The AccuWeather Enterprise API provides subscribers access to location based weather data via a simple RESTful web interface.
Access to the AccuWeather Enterprise API requires an API key. Contact email@example.com to receive an API key.
If required by the terms of your agreement, a partner code will be provided to you by your AccuWeather representative. Please append the assigned partner code to the links provided in the output. Click here for an example.
Data is available in more than 200 languages and dialects.
Use hostname: apidev.accuweather.com for development purposes only.
Use hostname: api.accuweather.com for production purposes only.
Data responses are returned in JSON.
SSL (Secure Sockets Layer) data encryption is also available for secure communication with your set up. This is done with the use of "https://" scheme in your URLs.
JSONP is available. Please use "parse_response" as the callback parameter.
Quick Start Guides are available in select localized languages for easier developer implementation.

Requests will return an appropriate response code.
It is possible to suppress error codes by passing allowError=false in the query. In that case, the response will always be 200, barring a 500 error from the server itself.
An error response will describe the specifics of any errors.

|Error Response Code||Response Name||Description|
|400||Bad Request||Request had bad syntax or the parameters supplied were invalid|

|404||Not Found||Server has not found a route matching the given URI|
|409||Service Unavailable||The server is currently unavailable|
|500||Internal Error||Server encountered an unexpected condition which prevented it from fulfilling the request|
|503||Conflict||The allowed number of requests has been exceeded|
