## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js/docs.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python/docs.md):

```bash
pip install apify-client
```

In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):

````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash

In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/integrations/mcp.md).

If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt).


# README

## Redirect Chain Tracer 🔗

**Follow every hop of any URL to its final destination.** Redirect Chain Tracer
takes a list of URLs and walks the full redirect chain — `301`, `302`, `307`,
`308`, `<meta http-equiv="refresh">` and JS-style hops — recording each step
until it reaches the final `2xx` page, a loop, or the max-hops limit. No API key,
no login, no setup.

Perfect for **SEO redirect audits**, **link tracing**, **security checks**, and
**migration QA**.

> Roughly **$0.50 per 1,000 URLs** traced. No proxies required.

---

### What it does

For each URL the actor:

1. Issues a `GET` request with **automatic redirect-following disabled**.
2. Records the hop: `{ url, status_code, location, type }` (the `Location`
   header resolved to an absolute URL).
3. Detects `<meta http-equiv="refresh">` redirects on `2xx` pages and follows
   them too.
4. Repeats until it hits a final `2xx`, a **redirect loop**, or **`maxHops`**
   (default 15).

You get back the complete chain, the final URL, the hop count, and flags for
whether it redirected and whether a loop was detected.

---

### Use cases

- **SEO redirect audits** — verify `301` vs `302`, spot redirect chains that
  leak link equity, and catch `http → https` / `www` inconsistencies.
- **Link tracing** — unwrap shortened links (`bit.ly`, `t.co`, tracking URLs)
  to see the real destination.
- **Security checks** — reveal where a suspicious link actually lands before
  anyone clicks it.
- **Migration QA** — after a site move or replatform, confirm old URLs redirect
  cleanly to their new homes with the fewest possible hops.

### FAQ

**Does it follow meta-refresh and JavaScript redirects?**
Yes — `<meta http-equiv="refresh">` redirects are detected and followed. Pure
client-side JS redirects are noted where the page exposes them; standard HTTP
and meta redirects are fully traced.

**What happens with a redirect loop?**
The actor detects loops and stops, setting `is_loop: true` so you can flag the
broken URL.

**Do I need an API key or proxy?**
No. Just provide URLs and run.

# Actor input Schema

## `mode` (type: `string`):

What the actor should do. 'trace' follows the redirect chain of each URL to its final destination.

## `urls` (type: `array`):

List of start URLs to trace. Each URL is followed hop-by-hop (301/302/307/308/meta-refresh) until it reaches a final 2xx page, a loop, or the max-hops limit. Missing http:// is added automatically.

## `maxHops` (type: `integer`):

Maximum number of redirects to follow per URL before stopping. Protects against redirect loops and very long chains.

## `maxItems` (type: `integer`):

Maximum number of URLs to process in a single run (safety cap). Extra URLs beyond this limit are ignored.

## Actor input object example

```json
{
  "mode": "trace",
  "urls": [
    "http://github.com",
    "http://google.com"
  ],
  "maxHops": 15,
  "maxItems": 200
}
```
