HTTP Dog API
Overview
HTTP Dog serves a photo of a dog for every HTTP status code (200, 404, 500, etc.), making it easy to visualize API responses in a fun way. Beginners use it to learn HTTP status codes by associating each code with a memorable dog image. It requires no authentication and returns a direct image file.
Beginner Tip
Append the status code as a number to the base URL — for example https://http.dog/200 — and you get a JPEG image of a dog representing that status code.

if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
