curl 'https://robohash.org/bytetools.png?size=200x200'

const res = await fetch("https://robohash.org/bytetools.png?size=200x200");
if (!res.ok) throw new Error(`Request failed: ${res.status}`);
const data = await res.json();
console.log(data);

import requests

res = requests.get("https://robohash.org/bytetools.png?size=200x200", timeout=20)
res.raise_for_status()
print(res.json())

• Give bots and service accounts recognisable identity images

• Visually distinguish account types using different sets
