🔎 Why scrape Bazos.cz?

Bazos.cz is the default online trading platform across the Czech Republic for buying and selling consumer electronics, mobile phones, used automobiles, bikes, construction equipment, furniture, real estate, and local services. Listings are organized across specialized category subdomains (auto.bazos.cz, mobil.bazos.cz, reality.bazos.cz, pc.bazos.cz, elektro.bazos.cz, etc.). Each listing card carries crucial market signals: an asking price, municipality and postal code, the exact publish date, an open public view counter, and seller information.

Collecting this market intelligence by hand is slow and unsustainable. Listings update constantly, items sell within hours, and Bazos offers no native API or export facility. Copy-pasting hundreds of ads across paginated result pages — while cleaning price strings like 1 699 999 Kč into numeric values — is tedious.

This Bazos scraper automates the entire process. It walks search results, eliminates duplicate items by ID, parses formatted prices into clean integers, tracks original price text (including "Dohodou" or "Nabídněte"), resolves the category from the listing subdomain, extracts listing dates and view counters, and optionally fetches the seller's name and full description.

Primary use cases for automated Bazos scraping:

• 💰 Second-Hand Resale & Arbitrage — spot underpriced iPhones, laptops, power tools, or bicycles for fast resale margins.
• 📈 Price Intelligence & Tracking — monitor what items actually list for across Czech regions and track price fluctuations over time.
• 📊 Supply & Demand Analytics — measure new listing frequency, inventory turnover, and average view counts per category.
• 🔥 Demand & Liquidity Indicators — use the public view counter and posting timestamp to evaluate customer interest and listing freshness.
• 🚗 Used-Car & Machinery Sourcing — dealers tracking specific car models, mileage, and replacement parts on auto.bazos.cz.
• 🏷️ Competitive Pricing — benchmark your retail prices against live Czech second-hand offerings.
• 🤖 AI & E-Commerce Repricing — feed structured classifieds data into valuation models, price alert bots, and market dashboards.

✨ What this Bazos.cz scraper does

• 🔎 Keyword Search Across All Categories — enter keywords like iphone, audi, kolo, macbook, or stůl. Each query searches across all Bazos category databases.
• 🔗 Direct URL Scraping — paste any Bazos search or category URL (including specific subdomains like auto.bazos.cz or reality.bazos.cz) into Start URLs to scrape filtered views directly.
• 📄 Unlocked Deep Pagination — automatically paginates through consecutive result pages via the native crz offset (~20 listings per page) to retrieve hundreds to thousands of de-duplicated listings.
• 💵 Clean Numeric Pricing — parsed into integer price (CZK) alongside original priceText ("1 699 999 Kč"). Non-numeric listings ("Nabídněte", "Dohodou") return price: null while preserving original text.

• 🗂️ Subdomain Category Resolution — automatically identifies the category from the listing's subdomain (auto, mobil, pc, elektro, reality, dum, prace...).

• 👤 Seller Name & Description — enable Scrape Detail Pages to capture seller name, full ad text, and masked phone preview.
• 🖼️ Cover Images — captures primary cover photo URLs for every listing.
• 🎯 Budget Filtering — filter listings directly at scrape time using minimum and maximum CZK thresholds (priceMin and priceMax).
• ⚡ High Throughput & Low Cost — pure HTTP requests with session rotation; scrapes 500 listings in ~30–50 seconds on standard Datacenter proxies.

💡 Best practices for scraping Bazos.cz

1. Category isolation via Start URLs: To avoid cross-category matches (e.g., searching for audi returning both actual cars and toy models), paste the specific subdomain URL https://auto.bazos.cz/?hledat=audi into startUrls.
2. Speed optimization: Leave scrapeDetails: false unless you explicitly require seller names. The standard listing view already captures price, date, views, location, and cover images at 5x higher speed.
3. Budget slicing: Use priceMin and priceMax to filter out accessory listings and focus on complete products.
4. Proxy efficiency: Datacenter proxies are configured by default. Do not use residential proxies for Bazos, as datacenter IP rotation operates with 100% success and avoids unnecessary per-GB bandwidth fees.
5. Freshness tracking: Sort your exported dataset by date descending to prioritize items published within the past 24 hours.

❓ Frequently Asked Questions (FAQ)

How fresh is the data?

All listings are extracted live at execution time. Posting dates and public view counts reflect real-time marketplace status.

Can I retrieve complete seller phone numbers?

Bazos.cz masks phone numbers on public web pages behind user verification. The scraper captures the seller display name and the open masked prefix (phonePreview, e.g. 775...), but full digits are not publicly exposed without interactive authentication.

How do view counts help with market intelligence?

High view counts combined with recent publish dates indicate hot, high-demand items. High views on older listings indicate asking prices may be set above market clearing value.

What happens if a listing has no numeric price?

For listings labeled "Dohodou" (by agreement) or "Nabídněte" (make an offer), price returns null while priceText preserves the original descriptive label.
