Free URL Shortener API

A REST API for developers that needs zero setup. No API key, no account, no rate limit contracts — just send a POST request and get a short URL back.

No Auth Required Sub-50ms Response JSON API Rate Limit: 10 req/min

What the API Does

🔗 Create Short URLs

Shorten any valid URL with a single POST request. Returns a short URL and creation timestamp.

🎯 Custom Aliases

Specify your own slug (3–16 alphanumeric characters) to create branded, memorable short links.

🔒 Password Protection

Optionally protect links with a password. Visitors must enter it before being redirected.

📊 Click Analytics

Every short link gets automatic click tracking — country, browser, OS, referrer, and timeseries.

📤 Export Data

Retrieve analytics as JSON via the API, or export as CSV, XLSX, or XML from the stats page.

😀 Emoji Support

Use emoji as slugs — create links like zip1.io/🚀 that stand out anywhere.

Quick Start

Pick your language and run it. No authentication step required.

curl -X POST http://zip1.io/api/create \
  -H "Content-Type: application/json" \
  -d '{"url": "https://your-long-url.com"}'
import requests

response = requests.post(
    "http://zip1.io/api/create",
    json={"url": "https://your-long-url.com"}
)
data = response.json()
print(data["short_url"])  # https://zip1.io/abc123
const response = await fetch("http://zip1.io/api/create", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({ url: "https://your-long-url.com" })
});

const data = await response.json();
console.log(data.short_url); // https://zip1.io/abc123

To use a custom alias:

curl -X POST http://zip1.io/api/create \
  -H "Content-Type: application/json" \
  -d '{"url": "https://your-long-url.com", "alias": "my-link"}'

Response Format

All responses are JSON. A successful POST /api/create returns:

{
  "short_url": "https://zip1.io/abc123",
  "created_at": "2026-03-05T10:00:00Z"
}

On error, the API returns an appropriate HTTP status code with a message field explaining what went wrong.

Rate Limits

The API is free and open, protected by sensible per-IP rate limits to keep it fair for everyone:

  • POST /api/create — 10 requests per minute
  • GET /api/stats/:code — 30 requests per minute
  • Shortlinks per day — up to 10 new links per IP per day

There is no paid tier, no API key purchase, and no approval process. These limits exist solely to prevent abuse.
