Sandbox: trial the OD API

The sandbox environment emulates the Oxford Dictionaries API and gives you the chance to evaluate its functionality. This provides a great opportunity to try the API before moving to a paid-plan Access to the Sandbox includes a finite amount of 500 calls to all languages and endpoints for the dictionary datasets, and is limited to the first letter of the alphabet.

For example: Querying the words endpoint in English:


Returns successful response (200 response code) because word begins with first letter of the alphabet.


Does not return a successful response (404 response code) because word does not begin with first letter of the alphabet.

Note that a 404 response for querying a letter that is not the first in the alphabet would not occur on the production API and is only the behavior of the Sandbox.

See all available languages here. See all endpoints here.

First letter of the alphabet

The first letter of the alphabet for all languages that use the Latin alphabet is a. Here are the first letters of the alphabet or equivalent for other languages offered on the API:

Language Language Code First Letter Equivalent

  3. app_id = "<your_app_id>"
  4. app_key = "<your_app_key>"
  5. language = "en-gb"
  6. word_id = "example"
  7. url = "" + language + "/" + word_id.lower()
  8. r = requests.get(url, headers={"app_id": <your_app_id>, "app_key": <your_app_key>})
