| 6 | Seems there's a problem with mashape web interface.
We're contacting their support.
We tested programmatically and it's working.
I suggest you try outside mashape console. If you use Linux based OS you can use cURL:
curl -X POST --include 'https://amtera.p.mashape.com/relatedness/en' \
-H 'X-Mashape-Key: PUT-YOUR-KEY-HERE' \
-H 'Content-Type: application/json' \
-H 'Accept: application/json' \
--data-binary '{"t1":"car","t2":"engine"}' | Tue 2:38 24/11/15 |
