Catawiki Auction Search & Watchlist

Unofficial — independent tool, not affiliated with, endorsed by, or sponsored by Catawiki. It reads only publicly visible pages. Support, reliability guarantees and the full disclaimer are at the bottom of this page.

Fetch live Catawiki search results or a list of exact lot URLs with current EUR bids, closing times, reserve state, source expert estimates, and core object attributes. Built for repeated collectors/dealers model searches and auction watchlists. Source estimates are guidance. Bids exclude fees, shipping and taxes, and are not settled sale prices.

Input

searchQueries: 1–5 keywords, default rolex and nikon; lotUrls: at most 50 canonical English lot URLs. Set searchQueries to [] for URL-only use. At least one input must be nonempty. maxItems: 1–100 global unique enriched lots, default 10. maxPagesPerQuery: 1–5, default 2. The default/canary example collects 10 across two keywords. Only HTTPS www.catawiki.com /en/s?q=...&page=... and /en/l/

Output

One type=auction_lot row per unique lotId, containing canonical lotUrl, object title/subtitle, auctionId, currentBidEUR/currency, bidAvailability, closingTime, auctionState, reservePriceSet/reservePriceMet, optional expertEstimateLowEUR/expertEstimateHighEUR, brand/model/referenceNumber/condition, first searchQuery/sourcePage, priceBasis and observedAt. Source specifications are factual labels, not authenticity or condition verification. Explicit watchlist rows have omitted searchQuery and sourcePage 0. Other embedded currency slots are not converted prices. Omit unavailable fields and preserve closed states. Intact auction records with no bid amount are returned with currentBidEUR omitted and bidAvailability no_reported_amount; this is not a failed search. Missing auction/status containers are structure errors. The observed never-bid source uses EUR=0 with an empty bid list; zero is omitted with no_reported_amount, not sold as a current market bid. Closed source status is preserved.

Uncharged OUTPUT records per-search advertised totals, pages/cards scanned, delivered rows, caps and stop reasons. Results use source relevance order; capped results are not a complete or unbiased market census. Lot URLs/IDs support scheduled diffing. No price-history dataset is kept inside the Actor. The source may extend closing times after a late bid.

Limits and failures

256MB, lightweight HTTP/JSON, no proxy or paid API. Maximum 126 GET attempts including robots, transport fallbacks and 5xx retries, 5MB decompressed per response, 25s/request, 300s/run and >=1s sequential pacing. Each GET may retry HTTP 5xx once on the same transport after a 2s backoff, within the existing attempt and run limits. A repeated 5xx fails before delivery or billing; rate-limit, classified auth-block, not-found, structure/body-budget and timeout failures are never retried. Successful Chrome fallback is remembered only for that host and run after the complete response passes validation. Upstream failure diagnostics include HTTP status and actual attempt count, without source URLs or lot IDs. Source schema/page/ID mismatch, blocks/login/challenges, rate limit, timeout, robots violation and abnormal empty result fail explicitly. Optional missing estimates are omitted. All-source failure or zero rows is never successful. A required failed source is surfaced; it is not silently omitted from the watchlist.

Privacy and rights

Explicit field whitelist excludes seller names/profiles/contacts, bidder histories or tokens, user/tracking IDs, messages, description, images, raw HTML and state. Current source terms, valid 15 September 2026, restrict copying/distribution; the exact applicable excerpt and DR-0007 guard are in the scout. This Actor is unaffiliated with Catawiki and performs no account action or bidding.

Pricing

One catawiki-lot-delivered primary event at $0.0015 per unique enriched row actually delivered. No custom start or secondary event and no actor-defined free rows. Platform memory/start charges may still apply. Require the available event allowance to cover maxItems before source work; fail charge-limit if insufficient. Recheck delivery parity, deduplicate before enrichment and billing.

If something goes wrong

• Wrong number or a failed run? Open a ticket on the Issues tab. I read every one and reply within 2 business days (Japan time).
• You never get a fake "empty" result. If the site can't be read, the run fails and says so.
• Delivered rows only. One validated unique row is one billable event. Duplicates, summaries, failed acquisition and undelivered rows are not charged.
• Checked every week. An automatic test runs this tool weekly; if the site changes, I fix it.
• Public source data only. No login or member/applicant records. Contact patterns are screened before delivery; prose may still name people.
