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.

Beginner Tip

Fetch https://randomfox.ca/floof/ and use the "image" field in the response — it is a full HTTPS URL ready to drop directly into an img src attribute.

Available Data

randomly generated data

customizable output format

Use case: Integrate random pictures of foxes data into web and mobile applications

Example Response

JSON Response

{
  "image_url": "https://api.example.com/randomfox/random.jpg",
  "status": "success"
}

Field Reference

image Full HTTPS URL of the random fox photo — use directly as an img src.

Implementation Example

Request

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

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

Metadata Score Breakdown

Estimated from metadata — endpoint not independently tested

This score is estimated from observable metadata — HTTPS support, authentication model, declared CORS, and documentation reachability — because the API requires authentication or exposes no publicly testable endpoint. The five-signal breakdown is only shown for live-tested APIs.
