RandomDog API
Overview
RandomDog returns a JSON object with the URL of a random dog image (JPEG, PNG, or GIF) sourced from user-submitted photos on random.dog. Beginners love it because getting a dog photo on screen takes just two lines of code — fetch the JSON, then set an img src to the "url" field. It requires no API key and is reliable enough for portfolio projects.
Beginner Tip
The JSON response contains a "url" field — use response.url to get the image address, then set document.getElementById("dog").src = response.url to display it instantly.
