Using the Owlbot.info API to Retrieve Word Definitions

If you’re looking to access a dictionary or thesaurus via an API, Owlbot.info is an excellent option. Not only does this API provide access to definitions and synonyms, but it also returns example sentences and images related to the word you’re searching for.

To get started using the Owlbot.info API, you’ll want to sign up for a free API key. Once you have your key, you can start making GET requests to the API endpoint, which is https://owlbot.info/api/v4/dictionary/. Here’s an example of how to make a request in JavaScript:

const API_KEY = 'your-api-key-here';
const word = 'example'; // replace with the word you want to search for
const endpoint = `https://owlbot.info/api/v4/dictionary/${word}`;

fetch(endpoint, {
    headers: {
        Authorization: `Token ${API_KEY}`,
        'Content-Type': 'application/json',
    .then((response) => response.json())
    .then((data) => {
    .catch((error) => {

In the above code block, we’re using the fetch function to make a GET request to the API endpoint with our API key as an authorization header. We then parse the JSON response and log it to the console.

The response object we get back from the Owlbot.info API includes a lot of useful information, including the word’s definitions, synonyms, and example sentences. Here’s an example of what the API response might look like:

  "definitions": [
      "type": "adjective",
      "definition": "serving as a typical example; characteristic.",
      "example": "the example paragraph is typical of the others"
      "type": "noun",
      "definition": "a thing characteristic of its kind or illustrating a general rule.",
      "example": "the example of the fine arts"
  "word": "example",
  "pronunciation": "ɪɡˈzɑːmp(ə)l"

With the data returned from the API, you can now display the word’s definitions and other linguistic information to your users. Remember to follow the API’s terms of use and rate limits to avoid exceeding your API request quota.
