API

Free JSON API for retrieving xkcd comics

Overview

The xkcd API provides RESTful access to xkcd's geeky, humorous webcomics. Key endpoints include fetching the latest comic (via /info.0.json) and specific comics by number (e.g., /123/info.0.json). Responses are JSON-formatted, containing details like title, image URL, alt text (xkcd’s signature witty commentary), publication date, and comic number. Use cases include integrating comics into educational tools, tech blogs, personal projects, or apps to add lighthearted, nerdy content for users.

Example Integration (JavaScript)

script.js JS


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