Several of the ones in the OP are incorrect. You should probably look a bit more into how varpbits work

 

A table of them is still not a bad idea, though. Can help people make their own API, if they for some reason wish to do so :p

Well, I only checked some of them against my code. But both of the prayer ones (Regular and Quickpray) are incorrect. You'll need to mask them.
