Pingdom is an uptime and performance monitoring service for web sites. I've blogged about Pingdom in the past. Their blog, Royal Pingdom, has interesting posts about the Internet, particularly about large sites. I use Pingdom's service on my business web site Dancing Bison.
Pingdom now has a new RESTful API. The API returns JSON content. It will replace their older SOAP-based API by the end of August 2011. The new API is read-write, and allows you to do anything that you can do via their control panel; in fact, they say that their new control panel will be built entirely upon this API (so they'll be eating their own dog food, a good sign :-)
It's still in public beta, but they say it will most likely not change. Also, the API is usable even for free Pingdom accounts.
Here is the post about the new API on Pingdom's blog:
