About this API

Free Dictionary is a dictionaries API described as: Definitions, phonetics, pronounciations, parts of speech, examples, synonyms. It is useful when you need programmatic access to definitions, phonetics, pronounciations, parts of speech, examples, synonyms from applications, dashboards, or internal tools. The published entry point or documentation is hosted at dictionaryapi.dev, which makes it a practical starting point for evaluating available endpoints and response formats. Because the listing indicates no authentication, it is comparatively easy to test for prototypes, demos, or lightweight integrations.

Use Cases

  • Add definitions, phonetics, pronounciations, parts of speech, examples, synonyms to a dictionaries discovery or reference application.
  • Build an internal script or scheduled job that pulls data from Free Dictionary for reporting or content updates.
  • Prototype a small web or mobile experience that surfaces definitions, phonetics, pronounciations, parts of speech, examples, synonyms to end users.

Code Examples

const url = "https://dictionaryapi.dev/";
const response = await fetch(url);
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);
