What it extracts

For every product in a category:

• 🏷️ Name and brand
• 💰 Price (₽), old price and discount % when on sale
• 📦 Stock quantity — the real available count (stock) plus an availability flag — most pet scrapers can't get this
• ⭐ Rating and review count
• 🔗 Product URL, product / offer IDs, article and image
• 🗂️ The category it came from and a scrapedAt timestamp

Run it on a schedule and diff the results to watch competitor prices and stock move.

How to use it

Three ways to point it at products — use any or all:

Track specific products (price monitoring):

• Paste product URLs (e.g. https://4lapy.ru/product/royal-canin-sterilised-37-2kg-3139109-1015911/). You get the current price, discount, stock and rating for exactly those products — ideal for watching your own or competitors' SKUs over time on a schedule.

Search by keyword (the quick way):

• Add search queries like корм, Royal Canin Sterilised, наполнитель. You get the top matching products (with price, stock and rating) for each query — perfect for "what does 4lapy charge for X".

Scrape whole categories (the full listing):

1. Add one or more category URLs (or just their slugs):
   • Full URL: https://4lapy.ru/catalog/koshki/
   • Slug only: koshki
   • Top-level slugs: koshki (cats), sobaki (dogs), gryzuny-i-khorki, ptitsy, reptilii, ryby, veterinarnaya-apteka. Subcategory URLs work too.
2. Pick a sort order (popular / price low-to-high / price high-to-low).
3. Set max pages per category (50 products per page) and an optional total max items cap.

Then run it and download or pull the results via API.

Monitor mode (track changes between runs)

Turn on monitorMode and run the actor on a schedule: it compares each run to the previous one (per the same input) and tags every product with what changed — so you catch competitor moves instead of re-reading a full dump each time. Each row gains:

• changeType — new, price_up, price_down, stock_change or unchanged
• previousPrice — the price at the last run
• priceLow30 / priceHigh30 — rolling 30-day low and high (spot fake discounts / MAP breaks)
• firstSeenAt / lastConfirmedAt — when the product first appeared and was last confirmed

Add onlyChanges to output just the products that moved — a clean delta you can pipe into alerts or a spreadsheet. Monitor mode is off by default, so normal runs are unaffected.

Cost & proxy

The 4lapy catalog is served by a public JSON API that works over Apify's datacenter proxy (the default) — so this scraper is cheap and fast, no residential proxy required. Apify's $5/month free credits go a long way here.
