There are some limts to this API.

  • There are no guarentees about availability, though we are highly available.
  • Currently the data is not versioned, so the latest is always returned.
  • If you abuse this service, we can limit your access at any time.

Use it however you want. Please be mindful of our bandwidth though. We are free and open but not currently funded, so bandwidth costs come directly out of our pockets.
