Art auction and estate sale monitoring
Track Sotheby's, Christie's, Heritage, Bonhams, and regional auction houses for new lots matching your interests.
Art collectors, dealers, and researchers watch auction houses on rolling cycles — new lots get cataloged days or weeks before each sale. WebMonitor.fyi monitors auction-house catalog pages for new lots matching artist names, periods, or categories you care about. Results pages get monitored after the sale for hammer-price data.
How to set it up
Identify the houses and categories
Sotheby's, Christie's, Heritage, Bonhams for international. Regional houses (Phillips, Doyle, Skinner) for narrower coverage.
Monitor the upcoming-lots URL per category
Each house's upcoming-sales page is filterable by category. Monitor the filtered URL — fewer false alerts.
Pre-sale and post-sale monitors
Pre-sale catches new lots as they're added. Post-sale captures hammer-price data for record-keeping or appraisal benchmarking.
Who uses this
- Collectors watching for works by specific artists
- Dealers tracking new inventory and competitor purchases
- Appraisers using realized-price data for valuation work
- Estate planners benchmarking comparable items
- Museums tracking deaccession sales
Honest limits
Auction monitoring catches what the house publishes publicly. Private sales, pre-auction reserves, and confidential negotiations are outside scope. Some smaller regional houses post less consistently — monitor reliability depends on the house.
Frequently asked questions
Can I track sale results to get hammer prices?

Does this work for online-only auction platforms?
Yes. Sotheby's online sales, Christie's online platform, LiveAuctioneers — all public pages work as monitor URLs.
