RoboHash API

Beginner's Pick Test Data / No Auth Required Beginner HTTPS
Free to Use Varies (check documentation)

Overview

RoboHash generates unique robot, monster, or human avatar images from any text string — just embed a URL in an img tag and you get an instant avatar. It is completely free with no API key required. Use it to give every user a distinct placeholder image during development.

Beginner Tip

RoboHash returns an image file directly, not JSON — use the URL as an img src in HTML or download it with a fetch/curl call. Different text inputs always produce different images.

Available Data

randomly generated data
customizable output format
RoboHash data via REST API

Example Response

JSON Response
{
  "status": "success",
  "data": {
    "result": "Data from RoboHash",
    "description": "Generate random robot/alien avatars",
    "timestamp": "2025-01-15T10:00:00Z"
  }
}

Field Reference

(binary image) Response body is a PNG/JPG/SVG image file — no JSON fields; use the URL directly as an image source

Implementation Example

Request
const url = "https://robohash.org/";
const response = await fetch(url);
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);

What Can You Build?

Common Errors & Troubleshooting

Same image for different inputs Identical or very similar strings hash to the same image
Use unique identifiers like user IDs or UUIDs as the path string
Image not displayed in browser CORS issue when fetching the image via JavaScript fetch()
Use the URL directly as an img src attribute instead of fetching with JS
Wrong avatar style returned Default is robot set (set1)
Add ?set=set2 (monsters), set=set3 (robot heads), or set=set4 (cats) to the URL

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.
