A tiny little dpaste.com API
When I created dpaste, I tried to make it both a simple browser-based tool and a simple RESTful API. With very little work you could write a script that created a new paste item with a single POST.
Over the life of the site a few people have discovered and played with that “secret” API. I’ve now made it a bit more official. The new API has its own URL (versioned, even!) and is more tolerant of missing data, just like the web form.
