Product Page Extractor: Price, Stock, GTIN & Variants from Any Store

Turn any online store's product pages into clean, structured product data: name, brand, price and currency, list (compare-at) price and discount, stock status, SKU, GTIN / EAN / UPC, MPN, category, condition, images, star rating, review count, shipping cost, return window and every variant (size, color...) with its own SKU, barcode, price and stock.

It works on most online stores, because stores publish this data in the standard schema.org Product format that search engines read for rich results and shopping listings: Shopify, WooCommerce, Magento / Adobe Commerce, BigCommerce, Salesforce Commerce Cloud, PrestaShop, Shopware, Wix, Squarespace and custom sites. Paste product URLs, or point the actor at a store's homepage, sitemap or category page and it finds the products for you.

Need a price tracker? Give the run a monitor name and schedule it: every run compares with the previous one and flags price drops, price rises and stock changes.

What does Product Page Extractor do?

• Reads the product data each page already publishes: schema.org JSON-LD first (Product, ProductGroup with variants, AggregateOffer), microdata next, Open Graph product tags last, plus the public product JSON on Shopify stores.
• Normalizes it into the same columns for every store: price as a number, currency, availability (InStock, OutOfStock, PreOrder, BackOrder...), inStock true/false, listPrice and discountPercent when the store shows a strike-through price.
• Lists variants with SKU, GTIN, price, stock and options (color, size, material).
• Resolves linked data (brands, offers and images stored elsewhere on the page).
• Discovers products from a store's sitemap (it reads robots.txt to find it; product sitemaps first, .xml.gz supported) or from a category / collection page.
• Detects the store platform (platform) and reports category pages you pasted by mistake instead of charging for them.
• Price monitor: remembers each product's last price and stock in a named key-value store on your Apify account and adds previousPrice, change, priceChange and priceChangePercent. Optionally outputs only the products that changed.
• Respects robots.txt. Pages without product data, blocked pages and refused sites are never charged.
• Honors the run's Max items option and your spend limit exactly.

Who is it for?

• E-commerce and pricing teams watching competitor prices, discounts and stock-outs.
• Brands checking MAP (minimum advertised price) compliance on their retailers' and resellers' own sites.
• Dropshippers and resellers tracking supplier prices and availability.
• Marketplaces, comparison sites and catalog builders importing products with GTINs and images.
• SEO agencies auditing product rich-result markup (missing GTIN, brand, availability or reviews).
• AI and data teams building product datasets.

Other columns: mpn, category, condition, priceValidUntil, seller, shippingCost, returnDays, images, description, finalUrl. With a monitor name: previousPrice, previousAvailability, previousCheckedAt, change, priceChange, priceChangePercent. Pages without product data come back with an error explaining why (no markup, blocked, category page, robots.txt) and are free.

Export as JSON, CSV, Excel or HTML, or read results through the Apify API.

How much does it cost?

• $3.00 per 1,000 products extracted (one product = one row, with all its variants)
• Pages without product data, blocked pages and refused sites: free
• $0.001 per run start

Worked examples:

1. Check 40 competitor products every morning: 40 × $0.003 = $0.12 a day, about $3.60 a month. With onlyChanges on you pay only for products whose price or stock changed.
2. Import a 1,500-product Shopify catalog with variants and barcodes: about $4.50.
3. MAP check of one product line across 25 reseller sites (200 pages): about $0.60.

Bronze, Silver and Gold Apify plans pay less per product. Compute is small (256 MB, plain HTTP, no browser).

Tips

• Whole store: put the homepage in discoverFrom; the actor reads the sitemap named in robots.txt. Shopify stores list products in /sitemap_products_1.xml, WooCommerce in /product-sitemap.xml.
• Daily price tracker: set monitorName, turn on onlyChanges, and add an Apify schedule. Connect a webhook, Slack or email integration to get the changed rows.
• Barcodes: gtin is read from gtin13 / gtin12 / gtin14 / gtin8 / gtin; Shopify variant barcodes come from the store's product JSON.
• Markup audit: run a store's sitemap with skipFailed off; empty gtin, brand or availability columns show what the store's product markup is missing for Google Shopping.

FAQ

Which stores work? Any store that publishes schema.org Product data, which is nearly every store that wants to appear in search results. A few big retailers block datacenter IPs; those pages are reported as blocked and not charged, and useResidentialProxy retries them.

Which sites are refused? Large marketplaces whose terms forbid automated access (for example Amazon, eBay, Walmart, AliExpress, Temu, Etsy) are not read. The actor is built for brand stores, D2C shops and retailers' own websites.

Is it legal? The actor reads publicly available pages you choose, follows robots.txt, and returns the product facts (prices, stock, identifiers) the stores publish for search engines. It does not log in and collects no personal data. Respect each store's copyright if you republish descriptions or photos.

Does it need a browser? No. Product markup is in the page source, so plain HTTP requests are enough: fast and cheap.

Where is the price history kept? In a named key-value store on your own Apify account (product-price-monitor-<name>). Delete it to start fresh, or use another monitor name.

Why is a page a "category/listing page"? You pasted a collection or search page (or the product URL redirected to one). Put such pages in discoverFrom to extract every product on them.

Integrations

Send products to Google Sheets, Airtable, Notion or your database with Apify integrations, run it from Make, Zapier or n8n, call it from Python or JavaScript with the Apify client, or let an AI agent use it through the Apify MCP server.
