Alternatively, you may retrieve the zettel as a parseable object / a symbolic expression by providing the query parameter enc=data:

# curl 'http://127.0.0.1:23123/z/00001012053300?enc=data&part=zettel'

If you print the result a little bit nicer, you will see its structure:

(zettel (meta (back "00001006000000 00001012000000 00001012053200 00001012054400")
