Overview

The Free Dictionary API provides a RESTful interface to access comprehensive word information via its primary endpoint: /api/v2/entries/{language}/{word}. Responses are in JSON and include definitions, phonetic transcriptions, audio pronunciation URLs, parts of speech, example sentences, and synonyms. It supports multiple languages (English, Spanish, French, etc.). Ideal for integration into educational apps for language learning, word games for real-time word details, writing tools for synonym suggestions, or browser extensions for quick lookups. No authentication is required, simplifying implementation for developers.

Example Integration (JavaScript)

script.js JS

fetch('https://dictionaryapi.dev/')
  .then(res => res.json())
  .then(data => console.log(data))
  .catch(err => console.error(err));
