If you include contact information (website or email), we can contact you if your string is associated to a security event. This string can be anything, and the more unique to your application the less likely it will be affected by a security event. You can get full details by visiting the header field definitions page at the World Wide Web Consortium site.Ī User Agent is required to identify your application.

Developers can override these headers for specific purposes (see the 'API Specifications' tab for more information). No private information is shared in a header, and this is a standard practice for all government and private sites.

For example, a commonly used header called 'UserAgent' tells a website what type of device you are using so it can tailor the best experience for you. Every request, either by browser or application, sends header information every time you visit any website. The new API will use headers to modify the version and format of the response. Proxies are more likely to reach the limit, whereas requests directly from clients are not likely. If the rate limit is execeed a request will return with an error, and may be retried after the limit clears (typically within 5 seconds). The rate limit is not public information, but allows a generous amount for typical use. As a public service of the United States Government, we do not charge any fees for the usage of this service, although there are reasonable rate limits in place to prevent abuse and help ensure that everyone has access. PricingĪll of the information presented via the API is intended to be open data, free to use for any purpose.

The API is based upon of JSON-LD to promote machine data discovery. The API was designed with a cache-friendly approach that expires content based upon the information life cycle. The National Weather Service (NWS) API allows developers access to critical forecasts, alerts, and observations, along with other weather data.
