A Planet API key allows you to access data programmatically using the Planet API so that you can build your own applications using our imagery.
Every Planet account has an API key and you can find yours by following the instructions at How do I get my API key?. The API key is highlighted at the top of the page.
You can also find your API key listed alongside your name and email address on your account page.
Please protect your API key. If anyone else gains access to it, they will be able to make requests that will use up your quota.
