Authentication & Security 2

NOAA — National Oceanic and Atmospheric Administration Gridpoints API declares 2 security schemes for authenticating requests. An API key is passed in the header as User-Agent (userAgent). An API key is passed in the header as API-Key (apiKeyAuth). By default, every request must be authenticated.

  • userAgent — We require that all consumers of the API include a User-Agent header in requests. This is due to a high number of scripts exhibiting abusive behavior (intentio…
  • apiKeyAuth — We are testing including a more traditional API Key system on certain endpoints. This is due to a large change in the weather.gov site. The API remains open an…
