1.7 series does not really have full API documentation, it’s much more complete(and tested) in 1.8 series, please see http://xibo.org.uk/manual-tempel/api/
We’d recommend that you wait for full 1.8 release or try the current 1.8 beta if you want to use API.
The 1.8 documentation will be moved to the main manual page once it has been release as stable - at that point we will make the 1.7 documentation available in another location - manual-tuttle.
