## 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.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

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

# README

## Website Migration & Redirect Intelligence Agent

Turn redirect checking into migration intelligence. This Actor verifies where each source URL actually lands, whether it matches the expected migration target, whether the final page is healthy and HTTPS, whether its canonical agrees with the destination, and whether routing changed since a previous snapshot.

### Why use this Actor

A migration can look successful while valuable URLs quietly land on the wrong page, collect multiple hops, lose HTTPS, change canonical targets or drift after a later deployment. This Actor produces one structured risk result per source URL so SEO, engineering and AI-agent workflows can act on evidence instead of manually following browser redirects.

### Key features

- Follow and record complete redirect chains.
- Validate expected source-to-target migration mappings.
- Check final HTTP status, HTTPS landing and canonical consistency.
- Detect redirect loops and excessive chains.
- Compare final URL, status, canonical and hop count with previous snapshots.
- Produce `migrationRiskScore`, `migrationReadiness`, `agentAction` and concise evidence.
- Optional fail-on-risk behavior for CI and release gates.
- Concurrent HTTP-first execution in a 256 MB runtime.

### Input

Provide public source URLs. Optionally add `expectedTargets` and `previousSnapshots` to turn a one-time audit into migration verification and ongoing drift monitoring.

```json
{"urls":["https://example.com/old"],"expectedTargets":{"https://example.com/old":"https://example.com/new"}}
```

### Output

Each source URL creates one dataset row containing the redirect chain, final URL and status, canonical evidence, expected-target match, changed snapshot fields, migration risk and an agent-oriented recommended action.

### Example

A source URL that lands on an unexpected destination with a conflicting canonical can return `migrationReadiness: BLOCK`, a high `migrationRiskScore`, and `agentAction: FIX_MIGRATION_MAPPING`. A stable one-hop redirect to the expected HTTPS destination can return `PASS`.

### Use cases

Use it for domain migrations, CMS and ecommerce replatforming, URL redesigns, HTTP-to-HTTPS projects, post-deploy QA, canonical drift monitoring, agency client audits, weekly routing checks and AI-agent release gates.

### Pricing

Pay per result. The base configured price is **$0.0025 USD per source URL result**, with tiered discounts applied by Apify account tier where supported. One source URL produces one independently useful migration intelligence row.

### Limitations

Only public HTTP/HTTPS targets are supported. Canonical analysis uses returned HTML and does not execute client-side JavaScript. The Actor reports observed routing and SEO signals; it does not guarantee search-engine indexing, rankings or traffic outcomes.

### Gen2 decision intelligence

This Actor preserves its original analysis and adds a decision layer with baseline awareness, regression detection, confidence, GO/WARN/BLOCK executive output, and an optional economic-impact estimate. Economic estimates are produced only when the user supplies `valuePerImpactUnitUsd`; the result states the calculation basis instead of inventing monetary value.

# Actor input Schema

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

Public source URLs to audit for redirects, final destinations and canonicals.

## `expectedTargets` (type: `object`):

Optional mapping of source URL to expected final destination for migration QA.

## `previousSnapshots` (type: `object`):

Optional prior snapshots keyed by source URL to detect routing or canonical drift.

## `maxUrls` (type: `integer`):

Maximum number of source URLs processed in one run.

## `maxRedirects` (type: `integer`):

Maximum redirect hops followed before the chain is treated as excessive.

## `timeoutSeconds` (type: `number`):

Per-request timeout for public HTTP requests.

## `concurrency` (type: `integer`):

Maximum parallel source URLs processed at once.

## `failRunOnRisk` (type: `boolean`):

Fail the run after writing evidence when any result meets the configured risk threshold.

## `riskThreshold` (type: `number`):

Migration risk score that triggers failRunOnRisk.

## `valuePerImpactUnitUsd` (type: `number`):

Optional user-supplied USD value per detected impact unit. Used only for transparent economic impact estimates.

## `monthlyRuns` (type: `integer`):

Optional number of comparable monthly runs used with value per impact unit for the economic estimate.

## `previousAnalysis` (type: `object`):

Optional previous Gen2 output used to compare decision metrics and detect regression between analyses.

## CLI example

```bash
echo '{}' |
apify call quanmatrix/url-redirect-canonical-auditor --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,quanmatrix/url-redirect-canonical-auditor"
        }
    }

```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
