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.

Available Data

Example Response

Illustrative shape only — we were not able to call this endpoint (it requires credentials or exposes no public sample URL), so the fields below show the kind of data this API returns rather than a recorded response.

JSON Response · Illustrative

{
  "message": "https://images.dog.ceo/breeds/retriever-golden/n02099601_1.jpg",
  "status": "success"
}

Field Reference

(binary image) The API returns a JPEG image directly, not JSON. Save it to a file or use the URL in an img src attribute.

status code (URL path) The HTTP status code is embedded in the URL path, e.g. /404.jpg for a 404 error dog photo.

Implementation Example

Calls a real endpoint of this API. Replace any placeholder credentials with your own key.

Request

const url = "https://http.dog/200.jpg";
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

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.

404 Not Found (image itself) You requested a status code that has no dog photo yet (e.g. an obscure 1xx code)

✓ Stick to common codes like 200, 301, 400, 401, 403, 404, 429, 500, 503

Empty response body You forgot to include the status code in the URL path

✓ Make sure your URL looks like https://http.dog/404.jpg, not just https://http.dog/

CORS error in browser Fetching the image URL cross-origin with fetch() instead of an img tag

✓ Use an <img> tag with the URL as the src attribute instead of fetching with JavaScript fetch()

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.
