Protocol used for pool mining

[pieppiep]

I'm trying to find the protocol or api used by the different miners to get work from the different pools but I can't find it.
Can anyone point me in the right direction?
Soap? json? something else?

Thanks both

The thing I want to make is a miner.
First to test if I understand everything an unoptimized software miner, later a fpga miner.
I don't care if it is slow, it's just a hobby project at the moment.

With the links Revalin gave I found a C# implementation called bitnet.
With only a few lines of code I succeeded to get some work to do and I fully understand the data the function returns so the next step is do some hashing with the sha256 function I already made earlier.
