RandomFox API

⭐ Beginner's Pick Animals / No Auth Required Beginner HTTPS
Free to Use Varies (check documentation)

Overview

RandomFox returns a random photo of a fox from a curated collection, providing a JSON object with a direct image URL and an index number identifying the specific fox. With no authentication required and a single-endpoint design, it is one of the easiest APIs to call in a first JavaScript project. You can also request a specific fox by its index to get repeatable results.

Common Errors & Troubleshooting

TypeError on response.image The field name is "image", not "url" or "src" — a common beginner guess
Log the full response with console.log(data) first to confirm exact field names before using them
Same fox image on every call Browser or fetch caching returning the same cached response
Append a cache-busting query string like ?_=Date.now() to the URL to force a fresh request
CORS error in local HTML file Browsers block fetch() calls made from file:// pages to remote APIs
Open your HTML through a local dev server such as VS Code Live Server or npx serve
