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
