RoboHash

API

Generate unique robot/alien avatars effortlessly

Overview

RoboHash offers a straightforward API to create custom robot, alien, or monster avatars from any input string (e.g., username, user ID). Its core endpoint is https://robohash.org/{input_text}, where each unique string produces a consistent avatar. Customize outputs via parameters like size (?size=200x200), format (PNG/JPG), avatar set (?set=set1 for robots, set2 for aliens), and background (?bgset=bg1). Responses are image files (no JSON/XML). Ideal for test data in app development (user avatars), prototyping mockups, or adding fun, unique avatars to projects without design resources.

Example Integration (JavaScript)

script.js JS


fetch('https://robohash.org/')
  .then(res => res.json())
  .then(data => console.log(data))
  .catch(err => console.error(err));
