Sign up for an API
Most services require you to sign up for their API, after which you’re assigned a “secret key” that grants you access. This key is included as part of the API request, letting the service know who’s making the API request — this key is unique to you and should not be shared with anyone else.
You can sign up for a Dark Sky account here.

Once you have your secret key, you’re ready to make your first API request.
