Not really, though I can provide any valid LaTeX input and get the appropriate result back. To be honest the setup is not ideal, as the input is first converted to a PDF file (that has to be saved in a temporary directory, along with other residual files, as "pdflatex" doesn't support stdout/stdin, for some reason), and only then to an image. Still though, it's much snappier than relying on online "latex to image" converters that basically do the same thing on a server somewhere.
