The Actor is free to use, and you only pay for the Apify platform usage, which gets cheaper the higher subscription plan you have.

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 ## Shopify Competitor Price Drop, New Product & Restock Monitor Watch your competitors' Shopify stores and get alerted the moment they **drop a price**, **launch a new product**, or **restock a sold-out item** — so you can react the same hour instead of the next week. Built for **e-commerce sellers, Shopify merchants, and Amazon sellers** who compete on price and assortment. Most scrapers just dump a catalog once; this one stores a snapshot between scheduled runs and reports **only what changed.** ### What you get per change | Field | Meaning | |---|---| | `type` | **PRICE DROP** / **NEW PRODUCT** / **RESTOCK** / PRICE RISE | | `product` / `variant` | What changed | | `was` → `now` (+ `drop`) | Old vs new price, and how much it fell | | `store` | Which competitor | | `checkedAt` | Timestamp of the check | ### How it works Every Shopify store exposes a public `/products.json` (no login, no anti-bot). The actor pulls each competitor's full catalog, compares it to the previous run's snapshot (stored in a persistent key-value store), and emits the differences. Run it on an Apify **schedule** (e.g. hourly/daily) to turn it into a true monitor. Optional `webhookUrl` posts changes straight to Slack / Zapier / Make / an email service. ### Input | Field | What it does | |---|---| | `stores` | Competitor store URLs, one per line | | `alertOnPriceDrop` / `alertOnNewProduct` / `alertOnRestock` | Which changes to report (all on by default) | | `alertOnPriceRise` | Also report price increases (off by default) | | `webhookUrl` | Optional — POST changes as JSON | > First run on a store sets a **baseline** (saves the snapshot). Changes appear > from the second scheduled run onward. ### Pricing Pay-per-result: a small fee per **store checked** plus per **change detected**. Merchants run it on a schedule against the same competitor set every day — so it's recurring by nature. ### Fair use Reads only **publicly available** store catalog data. Use for competitive pricing and assortment research. ### Deploy See [`DEPLOY.md`](./DEPLOY.md) — live on Apify in ~5 minutes. # Actor input Schema ## `stores` (type: `array`): One Shopify store URL per line, e.g. https://www.allbirds.com. (Works on any store that exposes /products.json.) ## `alertOnPriceDrop` (type: `boolean`): Flag when a competitor lowers a price (the key repricing signal). ## `alertOnNewProduct` (type: `boolean`): Flag when a competitor adds a new product/variant. ## `alertOnRestock` (type: `boolean`): Flag when a sold-out item comes back in stock. ## `alertOnPriceRise` (type: `boolean`): Also flag when a competitor raises a price. ## `maxProducts` (type: `integer`): Safety cap on how many products to pull per store. ## `webhookUrl` (type: `string`): If set, changes are POSTed here as JSON (Slack/Zapier/Make/email service). ## Actor input object example ```json { "stores": [ "https://www.allbirds.com" ], "alertOnPriceDrop": true, "alertOnNewProduct": true, "alertOnRestock": true, "alertOnPriceRise": false, "maxProducts": 2000 } ```` # 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 '' with your token const client = new ApifyClient({ token: '', }); // Prepare Actor input const input = { "stores": [ "https://www.allbirds.com" ] }; // Run the Actor and wait for it to finish const run = await client.actor("leadharbor/ecommerce-price-restock-monitor").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); }); // 📚 Want to learn more 📖?
