Every request below was executed against the live API on 20 Aug 2026, and the response shown is the real body it returned — not an illustration.

curl 'https://http.dog/200.json'

const res = await fetch("https://http.dog/200.json");
if (!res.ok) throw new Error(`Request failed: ${res.status}`);
const data = await res.json();
console.log(data);

import requests

res = requests.get("https://http.dog/200.json", timeout=20)
res.raise_for_status()
print(res.json())

If HTTP Dog does not fit, these animal apis cover similar ground. Every one was called before publishing, and each links to its own reference page with a working curl command and the response it returned.
