🔗 URL Unshortener

Expand bit.ly, t.co, goo.gl, and any shortened URL. Trace full redirect chains, detect loops and HTTPS downgrades.

Store Quickstart

Start with the Quickstart template (3 demo shortened URLs). For bulk processing, use Bulk Resolve (1,000 URLs, concurrency 20).

Key Features

• 🔓 Expand all shorteners — Works with bit.ly, t.co, goo.gl, tinyurl, ow.ly, buff.ly, and more
• 🔗 Full redirect chain — Every hop logged with URL + status code
• 🔄 Loop detection — Identifies infinite redirect loops and cyclic redirects
• 🔒 HTTPS downgrade detection — Flags URLs where https redirects to http
• ⚡ Bulk processing — Up to 1,000 URLs per run with 1-20 concurrency
• 📊 Hop count stats — Total hops per URL for ad network / tracker analysis

Use Cases

Who	Why
Ad fraud analysts	Detect cloaking by tracing redirect chains in ad URLs
Security teams	Resolve phishing links without clicking to identify payloads
Social media analysts	Expand t.co links from X/Twitter datasets for attribution
SEO auditors	Verify outbound shortened links resolve to intended destinations

Input

Field	Type	Default	Description
urls	string[]	(required)	Shortened URLs to resolve (max 1000)
maxRedirects	integer	10	Max redirect hops (1-20)
concurrency	integer	10	Parallel requests (1-20)

Input Example

{
  "urls": ["https://bit.ly/3abcdef", "https://t.co/xyz", "https://goo.gl/abc123"],
  "maxRedirects": 10,
  "concurrency": 10
}

Output

Field	Type	Description
originalUrl	string	The short URL provided as input
finalUrl	string	The final destination URL after all redirects
redirectChain	string[]	Full chain of intermediate URLs
totalHops	integer	Number of redirects followed
hasLoop	boolean	True if a redirect loop was detected
isHttpsDowngrade	boolean	True if any HTTPS→HTTP downgrade occurred
statusCode	integer	Final HTTP status code
error	string	null

Output Example

{
  "originalUrl": "https://bit.ly/3abcdef",
  "chain": [
    {"url": "https://bit.ly/3abcdef", "statusCode": 301},
    {"url": "https://example.com/landing", "statusCode": 200}
  ],
  "finalUrl": "https://example.com/landing",
  "totalHops": 2,
  "hasLoop": false,
  "isHttpsDowngrade": false
}

API Usage

Run this actor programmatically using the Apify API. Replace YOUR_API_TOKEN with your token from Apify Console → Settings → Integrations.

cURL

curl -X POST "https://api.apify.com/v2/acts/taroyamada~url-shortener-resolver/run-sync-get-dataset-items?token=YOUR_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{ "urls": ["https://bit.ly/3abcdef", "https://t.co/xyz", "https://goo.gl/abc123"], "maxRedirects": 10, "concurrency": 10 }'

Python

from apify_client import ApifyClient

client = ApifyClient("YOUR_API_TOKEN")
run = client.actor("taroyamada/url-shortener-resolver").call(run_input={
  "urls": ["https://bit.ly/3abcdef", "https://t.co/xyz", "https://goo.gl/abc123"],
  "maxRedirects": 10,
  "concurrency": 10
})

for item in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(item)

JavaScript / Node.js

import { ApifyClient } from 'apify-client';

const client = new ApifyClient({ token: 'YOUR_API_TOKEN' });
const run = await client.actor('taroyamada/url-shortener-resolver').call({
  "urls": ["https://bit.ly/3abcdef", "https://t.co/xyz", "https://goo.gl/abc123"],
  "maxRedirects": 10,
  "concurrency": 10
});

const { items } = await client.dataset(run.defaultDatasetId).listItems();
console.log(items);

Tips & Limitations

• Detect malicious URL chains by checking hasLoop and isHttpsDowngrade flags.
• Default maxRedirects: 10 is safe for legitimate shorteners. Increase only if needed.
• Use this before clicking any unknown short link in security-sensitive workflows.
• Combine with Meta Tag Analyzer to inspect the destination page metadata.

FAQ

What if the short URL is dead?

The chain shows the final status code (e.g., 404). hasLoop will be false; finalUrl will be the last URL reached.

Can it handle JavaScript redirects?

No — this is HTTP-level only. JS-based redirects (meta refresh, window.location) require a browser.

Is bit.ly rate-limited?

bit.ly may rate-limit aggressive requests. Use concurrency ≤ 10 for safety on shortener-heavy batches.

Will this follow tracking parameters?

Yes. The full URL including UTM tags is preserved at each hop.

Which shorteners are supported?

Any HTTP-based redirect — bit.ly, t.co, tinyurl, goo.gl, lnkd.in, custom shorteners. No special integration needed.

Will it click through tracking pixels?

It follows server-side HTTP redirects only, not JavaScript or meta-refresh redirects.
