The API is currently (Fri 19 August) undergoing maintenance and won’t be available again until Monday (22 August).

The good news…

Since launching we’ve been forced to close down at 5pm each evening as a result of a regular, scheduled shutdown of our network connection. This problem is being addressed by today’s maintenance and (fingers crossed) from next week the API will be accessible fulltime. This will enable more widespread use of the API and will provide the stability required by developers wishing to develop against it.
