The Crunch Interactive API documentation allows developers to try out the Crunch API. Simply kick open one of the endpoints below and click the 'Try it out!' button. The documentation will make a request of the Crunch API and display the response in either XML or JSON format.
The requests made by the interactive documentation are pre-authenticated, meaning that access to Crunch API has already been granted to this service. When developing an app to use the Crunch API the application will need to authenticate itself with Crunch following the OAuth 1.0 standard. The authentication mechanism is documented on the Authentication and OAuth page.
