Catawiki Lots Scraper

Scrapes Catawiki auction lot pages in bulk by lot ID range — no account or cookies required — and returns structured JSON with full lot details, bidding history, images, and auction metadata.

Key highlights

• No Catawiki account or cookies needed
• Scrapes any lot category: watches, art, collectibles, cars, jewelry, wine, and more
• Extracts complete lot data: title, brand, model, year, condition, expert estimates, bids, and images
• Full bidding history per lot via the Catawiki bids API
• Handles millions of lots in configurable batch sizes
• Outputs clean, structured JSON ready for analysis or export as CSV/Excel

What data does it extract?

Each result contains:

Core lot info: lot ID, lot URL, title, subtitle, description, source platform

Specifications (where present): brand, model, year of manufacture, case diameter, movement type, condition

Pricing & bidding: current bid (EUR), bid count, expert estimate min/max, auction start/end time, auction status (active/closed)

Media: main image URL, array of all additional image URLs (hosted on assets.catawiki.nl)

Auction context: auction name, categories, full raw bidding history

Metadata: favourite/watch count, SKU (if present in description), scraped timestamp

Output is available as JSON, CSV, or Excel via the Apify dataset export.

Use cases

• Data aggregation: Bulk-collect Catawiki listings and images for catalogue enrichment or comparison databases

Pricing

This Actor is free to use — you only pay for Apify platform compute time and proxy usage.

A typical run scraping 1,000 lots costs approximately $0.05–$0.15 in Apify platform credits, depending on proxy usage and lot page complexity.

New Apify accounts receive $5 in free credits — enough for approximately 30,000–100,000 lot scrapes.

Technical notes

• No account needed: This Actor does not require a Catawiki login or session cookies to operate
• Proxy: Apify residential proxy is used automatically to bypass Catawiki's bot protection. Runs without a proxy will be blocked.
• Deleted/invalid lots: Lots that no longer exist return no data and are skipped silently — this is normal for large ID ranges
• Rate limits: Catawiki applies rate limiting. For very large ranges, use the default batch size (100,000) and run at default concurrency
• Bidding history: Retrieved from the Catawiki buyer API (/buyer/api/v3/lots/{id}/bids) — may return empty for very old or deleted lots
• Active vs. closed lots: The status field indicates whether a lot is still open for bidding. Expert estimates and bid counts are available for both
• Image URLs: All images are hosted on assets.catawiki.nl and returned as full direct URLs
