Show HN: Delayping - a simple API for scheduling an HTTP request

API: http://delayping.herokuapp.com/

Documentation: http://docs.delayedping.apiary.io/

Source: https://bitbucket.org/bithiive/delayed-ping

As part of a larger tool we're building (http://docs.faction.apiary.io/) we needed an easy way to delay execution of a process until a set time. Rather than building a job system into the code, I decided to separate it out into a handy app.

This API allows you to submit a HTTP request to be performed either at a specified time or after a certain delay.

Code was written over the course of about 2 hours, and this is my first time deploying to Heroku also.
