## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
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.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## 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.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

### Automated Self-Serve Actor Overview

Monitor competitor product catalogs, track real-time stock availability, and capture price changes across **Shopify, WooCommerce, Magento, BigCommerce, and custom e-commerce storefronts** automatically.

#### How It Works

This Actor uses a multi-layered extraction engine:

1. **Shopify Native JSON API Detection**: Automatically checks `/products.json` endpoints on Shopify stores to extract full variant trees, SKUs, prices, and inventory status at high speed.
2. **Schema.org `Product` & `Offer` JSON-LD Parser**: Extracts structured pricing, currency, brand, SKU, and `in stock` / `out of stock` availability from any standard e-commerce product page.
3. **OpenGraph & Multi-Card Catalog Parser**: Captures `og:price:amount`, `product:price:currency`, and multi-item category listings when JSON-LD is absent.

#### Input Parameters

| Field | Type | Default | Description |
| :--- | :--- | :--- | :--- |
| `urls` | Array | `["https://books.toscrape.com/catalogue/page-1.html"]` | Storefront URLs, collection URLs, or direct product page URLs. |
| `maxItems` | Integer | `25` | Maximum verified product records to return. |
| `requireValidPrice` | Boolean | `false` | Filter output to only include products with a verified numeric price. |
| `inStockOnly` | Boolean | `false` | Filter output to only include currently available products. |

# API

You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup.

## JavaScript example

```javascript

## CLI example

```bash
echo '{
  "urls": [
    "https://books.toscrape.com/catalogue/page-1.html",
    "https://books.toscrape.com/catalogue/page-2.html"
  ]

apify call technicaltherapist/ecommerce-price-stock-tracker --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,technicaltherapist/ecommerce-price-stock-tracker"
        }
    }
}
```

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).
