close it

I tested it again, and didn’t find the problem you met, have you use it follow the mashape example, like:

curl -X POST --include ‘https://textanalysis.p.mashape.com/nltk-wordnet-lemmatizer’
-H ‘X-Mashape-Key: your mashape key here’
-H ‘Content-Type: application/x-www-form-urlencoded’
-H ‘Accept: application/json’
-d ‘text=this is word lemmatize test’

Note that you should subscribe one of the plan to get the mashape key to use it
