Test the API

You can test the API and develop your own application with our test translate API – for free.

Test the test API with:

Important note (!):
The initial API call might take up to 15 seconds because the heroku dyno falls asleep after 30 minutes of inactivity. (The test API runs on a free heroku dyno.)

Further limits of the test API:
The test API contains only a subset of the complete collocation database. Only highly significant collocations (significance > 30000) are included. Therefore only 6 thousand collocations are included in the test API. The paid API (see below) contains more than 4 million collocations.

API response
