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.

Request skeleton. The URL below is this API's documentation page, not a live endpoint — swap in the path you need from the provider's docs before running it.
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); What Can You Build?

How This API Fails
We deliberately sent this API a broken request and recorded exactly what came back on 2026-08-10. Knowing the shape of an error before you hit it makes error handling much easier to write.
Returned an HTML error page rather than JSON — worth knowing if your client assumes every response can be parsed as JSON.
Common Errors & Troubleshooting
Generated guidance based on this API's documentation, not observed by us. Treat it as a starting point and check against the provider's own error reference.
