Shopify Product Scraper & Price Monitor

Extract the product catalog of any public Shopify store: every product and variant with price, compare-at price, stock status, SKU, options, vendor, tags and images. Turn on monitor mode and each run returns only what changed since the last run: new products, price and stock changes, and removed products.

The Actor reads the public products.json feed that Shopify stores serve. No login, no browser and no proxies, so runs are fast and cheap.

What you get

• One dataset item per product, with all variants nested inside it.
• Price summary per product: priceMin, priceMax, compareAtPriceMax, onSale, available, availableVariantCount.
• Shop name and currency from the store's public meta.json.
• Whole stores or single collections (https://kith.com/collections/footwear), several stores in one run.
• Monitor mode: changeType = new, changed or removed, plus a changes list with old and new values per variant (price, compare-at price, availability, added or removed variants, title).
• A SUMMARY record in the key-value store with the status of every store (products found, items saved, full catalog or not, error message).

In monitor mode, a changed product has the same fields plus changeType and changes. A real example from monitoring kith.com/collections/footwear (other fields omitted):

{
  "title": "Giorgio Armani & Kith Espadrilla - Deer Black",
  "priceMin": 895,
  "currency": "USD",
  "changeType": "changed",
  "changes": [
    {
      "field": "available",
      "variantId": 45132888998016,
      "variantTitle": "45",
      "old": false,
      "new": true
    }
  ]
}

Monitor mode

1. Run once with monitorMode: true. This saves a baseline in the named key-value store shopify-catalog-monitor-state in your account and outputs every product as new.
2. Schedule the same input (for example daily). Each run outputs only products that are new, changed or removed, so you pay only for changes.
3. Use the Changes dataset view, or connect a webhook or integration to get alerts.

Each store or collection URL has its own baseline. Products are reported as removed only when both this run and the previous one read the full catalog, so a product limit never produces false removals.

Pricing

Pay per event:

Event	Price
Store or collection read (charged once per store that returns products)	$0.002
Product saved to the dataset	$0.0005 ($0.50 per 1,000)

Examples: 1,000 products from one store cost $0.502. A daily monitor of a 2,000-product store with 15 changes costs $0.0095 per run. Stores that fail (not Shopify, blocked) are not charged.

Use cases

• Track competitor prices, discounts and restocks.
• Build product feeds or price comparison data from brand stores.
• Research a store's assortment: vendors, product types, price ranges, new launches.
• Get alerts when a product comes back in stock.

Limits

• Works only with Shopify stores that serve the public /products.json feed. Some stores disable it or block automated requests (for example shop.tesla.com returns HTTP 403); those are skipped with a clear message in the log and in SUMMARY. The Actor does not try to bypass blocks.
• Shopify's feed serves at most 25,000 products per store or collection. For bigger stores, use collection URLs.
• The feed does not include exact inventory counts, barcodes or reviews. available is Shopify's in-stock flag per variant.
• Prices are in the store's default currency (currency). Market-specific prices are not included.
• Product URLs in the output use the store's primary domain. Single product URLs are not accepted as input; the Actor extracts the whole store instead.

FAQ

How do I know if a site is a Shopify store? Open https://<site>/products.json in a browser. If you see JSON with products, the Actor works on it.

Why did a store fail? See the run log or the SUMMARY record. not found means the site is not on Shopify or hides the feed; HTTP 403, 429 or 430 means the store blocks or rate-limits automated access. A collection that does not exist returns no products; it is reported as empty and not charged.

Can I monitor only one category? Yes, use a collection URL such as https://www.allbirds.com/collections/mens.

How do I reset monitoring? Delete the record for the store in the shopify-catalog-monitor-state key-value store (or the whole store). The next run saves a new baseline.

What happens if a run reaches my maximum cost per run? The Actor stops cleanly. In monitor mode the baseline of the interrupted store is not updated, so the next run reports those changes again instead of losing them.

Is personal data collected? No. The output contains only product data and the shop's name and currency.
