## 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

## Chrome Web Store Scraper

Extract structured data for any Chrome Web Store extension: ratings, user counts, category, **developer name and email**, version, size, last-updated date, supported languages, description, and user reviews. Scrape specific extensions, search by keyword, or crawl the **entire catalogue** (~320,000 extensions).

Perfect for market intelligence, competitor tracking, and developer-lead generation.

### Four ways to use it

| Mode | Input | Notes |
|------|-------|-------|
| **Specific extensions** | `extensionUrls` | Detail URLs or raw 32-char IDs. Fastest. |
| **Keyword search** | `queries` | Discovers and scrapes every matching extension. |
| **Full catalogue** | `scrapeAllApps: true` | Crawls the whole store via its sitemap (cap with `maxItems`). |
| **Reviews** | `includeReviews: true` | Adds user reviews to each extension. Works with any mode. |

### Output

One dataset item per extension:

| Field | Description |
|-------|-------------|
| `id` | 32-char extension ID |
| `name` | Extension name |
| `url` | Detail page URL |
| `iconUrl` | Icon image URL |
| `rating` | Average rating (e.g. `4.7`) |
| `ratingCount` | Number of ratings |
| `users` | Weekly user count |
| `category` | Category (e.g. `Privacy & Security`) |
| `version` | Current version |
| `size` | Package size |
| `lastUpdated` | Last update date (ISO) |
| `developer` | Developer name |
| `developerEmail` | Developer contact email (when published) |
| `tagline` | Short summary |
| `description` | Full description |
| `languages` | Supported languages |
| `websiteUrl`, `privacyPolicyUrl` | Developer links (when present) |
| `reviews` | Array of `{ author, rating, text, postedAt, version, language }` (when `includeReviews`) |

### Example input

```json
{
  "queries": ["ad blocker"],
  "maxItems": 50,
  "includeReviews": true,
  "maxReviewsPerExtension": 20
}
```

### Notes

- Extension data, the catalogue, and reviews are read directly over HTTP; keyword search uses a real browser because the store's search results are rendered client-side.
- `developerEmail` is only present when the developer chose to publish a contact address.
- Review collection is paged in batches of 10 up to `maxReviewsPerExtension`.

# Actor input Schema

## `extensionUrls` (type: `array`):

Specific extensions to scrape. Accepts full detail URLs (https://chromewebstore.google.com/detail/.../<id>) or raw 32-char extension IDs.

## `queries` (type: `array`):

Keywords to search the Chrome Web Store for (e.g. "ad blocker", "screenshot"). Discovered extensions are then fully scraped. Search uses a real browser, so it is slower than the other modes.

## `scrapeAllApps` (type: `boolean`):

Crawl EVERY extension via the store sitemap (~320,000 extensions). Use "Max extensions" to cap the run. Ideal for market intelligence and developer-lead generation.

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

Maximum number of extensions to scrape across all modes. Set 0 for no limit (only sensible with specific URLs).

## `includeReviews` (type: `boolean`):

Attach user reviews (author, rating, text, date, version, language) to each extension under a "reviews" array.

## `maxReviewsPerExtension` (type: `integer`):

Upper bound on reviews collected per extension when "Include reviews" is on. Reviews are paged in batches of 10.

## `reviewsLanguage` (type: `string`):

Interface/review language code (en, pt, de, es, fr, ja, ...). Affects review language filtering and localised labels.

## `sitemapShardLimit` (type: `integer`):

Full-catalogue mode only. Limit how many of the ~33 sitemap shards to enumerate (0 = all). Useful for sampling the catalogue.

## Actor input object example

```json
{
  "extensionUrls": [
    "cjpalhdlnbpafiamejdnhcphjbkeiagm"
  ],
  "queries": [
    "ad blocker",
    "password manager"
  ],
  "scrapeAllApps": false,
  "maxItems": 100,
  "includeReviews": false,
  "maxReviewsPerExtension": 20,
  "reviewsLanguage": "en",
  "sitemapShardLimit": 0
}
```
