## What's an Apify Actor?

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
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.md):

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

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

## Wayback Machine Bulk Lookup

Look up Wayback Machine (archive.org) snapshots for any URL or list of URLs. Returns the full capture timeline, optional snapshot HTML-to-markdown content, and a live-vs-snapshot text diff. Built for OSINT analysts, journalists verifying sources, SEO teams recovering link-rot, and legal evidence collection.

---

### What this actor does

For each input URL, the actor:

1. **Queries the Wayback CDX API** to retrieve the snapshot index in your specified date range and capture limit
2. **Optionally fetches snapshot HTML** for each capture and converts it to markdown (for reading or archiving)
3. **Optionally fetches the current live URL** and computes a line-level text diff against the most recent snapshot (to detect page changes)

Each output record contains the full snapshot timeline plus optional diff and content fields.

---

### Input

| Field | Type | Default | Description |
|---|---|---|---|
| `urls` | array of strings | — | **Required.** URLs to look up in the Wayback Machine |
| `maxItems` | integer | — | Maximum total output records across all URLs |
| `dateFrom` | string | — | Earliest snapshot date to include (ISO date, e.g. `2020-01-01`) |
| `dateTo` | string | — | Latest snapshot date to include (ISO date, e.g. `2024-12-31`) |
| `captureLimit` | integer | `100` | Max snapshots per URL |
| `fetchSnapshotContent` | boolean | `false` | Download snapshot HTML and convert to markdown |
| `diffWithLive` | boolean | `false` | Compute text diff between latest snapshot and current live URL |
| `proxyConfiguration` | object | none | Optional proxy config (usually not needed for Wayback) |

**Example input:**

```json
{
  "urls": [
    "https://example.com/news/2024-article",
    "https://example.com/about"
  ],
  "dateFrom": "2023-01-01",
  "dateTo": "2024-12-31",
  "captureLimit": 50,
  "diffWithLive": true
}
````

***

### Output

One record per input URL.

| Field | Type | Description |
|---|---|---|
| `url` | string | The input URL |
| `snapshotCount` | number | Number of snapshots found in the date range |
| `firstCaptured` | string | Earliest snapshot timestamp (ISO 8601) |
| `lastCaptured` | string | Latest snapshot timestamp (ISO 8601) |
| `captures` | array | Snapshot entries — each a JSON-encoded string with `timestamp`, `archiveUrl`, `status`, `mimetype`, and optionally `contentMarkdown` |
| `diff` | object | `{ addedLines, removedLines, changedRatio }` — only present when `diffWithLive=true` |
| `liveStatus` | number | Current HTTP status of the live URL — only present when `diffWithLive=true` |
| `finalLiveUrl` | string | Final URL after redirects |
| `status` | string | `success`, `timeout`, or `error` |
| `errorMsg` | string | Error details on failure, `null` on success |

**Example output record:**

```json
{
  "url": "https://example.com/news/2024-article",
  "snapshotCount": 14,
  "firstCaptured": "2024-03-12T08:42:00Z",
  "lastCaptured": "2026-04-29T22:11:00Z",
  "captures": [
    "{\"timestamp\":\"2026-04-29T22:11:00Z\",\"archiveUrl\":\"https://web.archive.org/web/20260429221100/https://example.com/news/2024-article\",\"status\":200,\"mimetype\":\"text/html\"}"
  ],
  "diff": { "addedLines": 12, "removedLines": 3, "changedRatio": 0.04 },
  "liveStatus": 200,
  "finalLiveUrl": "https://example.com/news/2024-article",
  "status": "success",
  "errorMsg": null
}
```

***

### Dataset views

The actor produces two dataset views in the Apify console:

- **Capture Timeline** — `url`, `snapshotCount`, `firstCaptured`, `lastCaptured`, `captures`
- **Live vs Snapshot Diff** — `url`, `liveStatus`, `diff`, `lastCaptured`

***

### Rate limits and performance

The actor respects Wayback Machine's rate limits:

- CDX API queries: ~10 requests/second (110ms minimum delay)
- Snapshot content fetches: ~1-2 requests/second (700ms minimum delay)

For large batches with `fetchSnapshotContent=true`, expect longer runtimes. The default timeout is 2 hours. Start with a small `captureLimit` (e.g. 10) to estimate runtime before running at full scale.

***

### Use cases

- **OSINT / research**: Check whether a source URL existed, when it was captured, and how its content has changed
- **Journalism**: Verify archived versions of articles or government pages for fact-checking
- **SEO / link-rot recovery**: Find archived versions of dead inbound links and plan redirects or outreach
- **Legal evidence**: Retrieve timestamped snapshots of web pages for documentation
- **Web archiving**: Bulk-check coverage for a list of URLs before deeper archiving work
