## 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`).

# README

## Shopify Store Product, Price & Stock Tracker

**Track products, prices, variants and stock levels** on any public Shopify storefront.

Detect new, changed and removed items between runs. Ideal for competitive monitoring, dropshipping, price intelligence and inventory alerts.

[![Actor](https://apify.com/actor-badge?actor=lomo-dev/shopify-store-tracker)](https://console.apify.com/actors/FrZLD0SL3copWGqxO)

***

### 🚀 What you get

- Full product + variant data (title, price, SKU, availability, images, etc.)
- **Change detection** across runs (new / changed / removed)
- Optional collection mapping
- Configurable max products and polite request delays
- Snapshot storage for historical comparison

***

### 📥 Input

| Field | Default | Description |
|-------|---------|-------------|
| `storeUrls` | required | Shopify storefront URLs or domains |
| `maxProducts` | 1000 | Max **products** per store (not variants) |
| `trackChanges` | true | Compare with previous snapshot |
| `onlyChanges` | false | Output only new/changed/removed items |
| `includeCollections` | false | Map collection handles |
| `snapshotStoreName` | shopify-tracker-snapshots | Named KV store for snapshots |
| `requestDelayMs` | 1000 | Delay between requests |

#### Example input

```json
{
  "storeUrls": ["https://hydrogen-preview.myshopify.com"],
  "maxProducts": 5,
  "trackChanges": false,
  "includeCollections": false,
  "requestDelayMs": 1000
}
```

On that demo store, `maxProducts: 5` still writes on the order of **~140 dataset rows**, because each product can have many variants. Expect **one paid result per variant**, not per product.

***

### 📤 Output

**One dataset item per variant** (or change event) with product details, price, stock status and change flags when tracking is enabled. `maxProducts` caps how many products are fetched; billed rows follow the variant count.

***

### Example output

Sample rows from a real owner run (public scrape data):

### 💰 Pricing (Pay-per-event)

| Event | Price |
|-------|-------|
| Actor start | **$0.0001** per start, charged once per GB of run memory |
| Dataset result | **$0.0009** per variant / change row written |

**Memory:** the default is **512 MB**, which bills a single start event.

Example: Store demo with `maxProducts: 5` → ~140 variant rows ≈ $0.0001 + 140 × $0.0009 ≈ **$0.126**.

***

### ⚙️ Memory limits

- Min: **512 MB**
- Max: **2048 MB**

***

### Notes

- Works on public Shopify storefronts (uses `/products.json` style endpoints).
- Be polite with `requestDelayMs` on large stores.
- Respect the store’s terms of service.

# Actor input Schema

## `storeUrls` (type: `array`):

Shopify storefront URLs or domains, e.g. https://hydrogen-preview.myshopify.com

## `maxProducts` (type: `integer`):

Upper limit of products fetched per store (each product yields one row per variant).

## `trackChanges` (type: `boolean`):

Compare with the previous snapshot (named key-value store) and add change fields.

## `onlyChanges` (type: `boolean`):

With trackChanges, output only new/changed/removed variants.

## `includeCollections` (type: `boolean`):

Fetch /collections.json and add collection handles to each product (extra requests).

## `snapshotStoreName` (type: `string`):

Named key-value store holding previous snapshots. Use different names to keep separate tracking histories.

## `requestDelayMs` (type: `integer`):

Polite delay between requests to the same store.

# 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
import { ApifyClient } from 'apify-client';

// Initialize the ApifyClient with your Apify API token
// Replace the '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {
    "storeUrls": [
        "https://hydrogen-preview.myshopify.com"
    ]
};

// Run the Actor and wait for it to finish
const run = await client.actor("lomo-dev/shopify-store-tracker").call(input);

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach((item) => {
    console.dir(item);
});

# Replace '<YOUR_API_TOKEN>' with your token.
client = ApifyClient("<YOUR_API_TOKEN>")

# Prepare the Actor input
run_input = { "storeUrls": ["https://hydrogen-preview.myshopify.com"] }

# Run the Actor and wait for it to finish
run = client.actor("lomo-dev/shopify-store-tracker").call(run_input=run_input)

# Fetch and print Actor results from the run's dataset (if there are any)
print(f"💾 Check your data here: https://console.apify.com/storage/datasets/{run.default_dataset_id}")
for item in client.dataset(run.default_dataset_id).iterate_items():
    print(item)

## CLI example

```bash
echo '{
  "storeUrls": [
    "https://hydrogen-preview.myshopify.com"
  ]
}' |
apify call lomo-dev/shopify-store-tracker --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,lomo-dev/shopify-store-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).
