RESTful Web Service to calculate readability

Readability formula:
${\mathrm{SMOG}}_{\mathrm{en}}=1.043*\sqrt{\mathrm{bigWords}*\frac{\mathrm{30}}{\mathrm{sentences}}}+3.1291$

${\mathrm{WSTF}}_{\mathrm{de}}=0.2656*\mathrm{sentenceLength}+0.2744*\mathrm{percentageBigWords}-1.693$

${\mathrm{Lix}}_{\mathrm{fr}}=\left(\frac{\mathrm{words}}{\mathrm{sentences}}\right)+100*\left(\frac{\mathrm{words\; more\; than\; 6\; letters}}{\mathrm{words}}\right)$
(also usable for English, German, Greek and Swedish)

${\mathrm{HuertaReadingEase}}_{\mathrm{es,pt}}=206.84-(0.60*\mathrm{syllables\; per\; 100\; words})-(1.02*\mathrm{sentences\; per\; 100\; words})$

${\mathrm{Gulpease}}_{\mathrm{it}}=89+\frac{300*\mathrm{sentences}-10*\mathrm{characters}}{\mathrm{words}}$
