## 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 Edge & Firefox Store Scraper

A high-performance, lightweight Apify Actor that scrapes structured metadata, user install counts, ratings, sizes, and versions from the **Chrome Web Store**, **Microsoft Edge Add-ons**, and **Firefox Browser Add-ons (AMO)** — without getting blocked.

***

### ⚡ Why this Actor?

- **Multi-store in one Actor**: Scrape Chrome, Edge, and Firefox from a single input.
- **HTTP-first search**: The search engine hits store search APIs directly (no headless browser needed = 5× cheaper than competitors).
- **Playwright fallback for detail pages**: Only launches Chromium when scraping extension detail pages, keeping compute costs low.
- **Anti-bot built-in**: Realistic browser fingerprints + residential-proxy-first design.
- **Optional review scraping**: Pull individual Chrome Store reviews with star ratings for sentiment analysis.

***

### 🔍 Input Parameters

| Field | Type | Required | Default | Description |
|---|---|---|---|---|
| `startUrls` | Array | One of | — | List of extension detail URLs from Chrome, Edge, or Firefox. |
| `searchKeyword` | String | One of | `""` | Keyword to search across all 3 stores (e.g. `Ad Blocker`). |
| `scrapeReviews` | Boolean | No | `false` | If true, also scrape individual Chrome Store reviews. |
| `maxResults` | Integer | No | `100` | Max number of extensions to scrape. |
| `proxyConfiguration` | Object | No | — | Apify proxy config (Residential recommended at scale). |

### 💰 Monetization: Pay-Per-Result

- **Actor Start Fee:** `$0.05`
- **Result Fee:** `$0.001` per data record (50% cheaper than competitor scrapers charging $0.002).
- **Bronze / Silver / Gold discounts** available for Apify subscription users.
- **Compute Costs:** Free for users (compute is platform-paid).

***

### 💡 Best Practices

- **Use a Residential Proxy** if you intend to scrape more than 50 extensions per run — Chrome Store rate-limits aggressively.
- **Disable `scrapeReviews`** unless you really need them — it adds 2-3× latency per extension.
- **Sort by `users` desc** in your dataset to spot the highest-impact extensions first.

***

### 💼 Use Cases

- **Competitive Intelligence**: Track competitor extensions' user growth, rating drops, and version cadence.
- **Lead Generation**: Find successful extensions in your niche to contact their developers for partnerships.
- **Market Research**: Build a live database of the entire browser-extension ecosystem for VC, analytics, or SEO tools.
- **Developer Tools**: Monitor your own extension's rating trends and react to negative reviews.

# Actor input Schema

## `startUrls` (type: `array`):

Provide one or more Chrome Web Store extension details URLs to scrape.

## `searchKeyword` (type: `string`):

Optional search term. Scrapes search result items. Leave startUrls empty to only scrape search results.

## `scrapeReviews` (type: `boolean`):

If checked, the scraper will also scrape individual user reviews (author, rating, text, date) for each extension and save them as separate relational dataset items.

## `maxResults` (type: `integer`):

Limit the maximum number of extensions to scrape.

## `proxyConfiguration` (type: `object`):

Specifies proxy server settings. Using proxies is recommended to prevent Google from rate-limiting your crawler.

{
  "startUrls": [
    {
