Ask HN: Is there a service that will submit an API request on my behalf?

For instance, I have an API call that remaps an Elastic IP to another EC2 instance in case there's a failure. I have the call saved on my mac, but in case I had a failure while I was out of the office, it would be nice if I could visit a webpage, send an email, tweet something, etc, and a service would send the API call on my behalf.

Seems simple enough, but I can't find anybody out there doing it.
