(Ooops probably answered Denis only and not the group. Here we go again!)

AFAICT filters are document AST to AST transformations. In this Python 
library, docs (Pandoc instances) represent this AST, so a typical AST 
(in-place) transform would be:

import pandoc
from pandoc.types import *

def uppercase(doc): 
    for elt in pandoc.iter(doc):
        if isinstance(elt, Str):
            elt[0] = elt[0].upper() # elt: Str(Text)

If you need to make a markdown to markdown transformation instead, you read 
the input markdown, transform it then write it back:

>>> markdown = "Hello world!"
>>> doc = pandoc.read(markdown)
>>> uppercase(doc)
>>> markdown = pandoc.write(doc)
>>> print(markdown)
HELLO WORLD!

There are more examples here:

and a documentation of common patterns here:
