Luxury & Resale Data Scraping

No, and this is the firmest boundary in the service. We capture the authentication claim as stated with authentication_verified permanently false.

Authentication requires physical examination by qualified specialists. No data signal substitutes for it, and if a client acted on an implied assessment and a buyer received a counterfeit, the liability chain would run through the vendor's claim. We flag anomalies — below-market asks for stated condition, unusual seller volume, inconsistent reference details — as starting points for your team.

Published wording is retained exactly and mapped to a normalised five-grade scale with a mapping confidence per platform. The mapping is documented in the scope document so you can inspect and disagree with it.

We also record whether grading is seller-declared or platform-assessed, because that distinction matters more than the grade itself. And we never average across grades to produce a single item price — a price without condition is not a price in this market.

About 88%, with confidence on every link. Resale listings are user-written with inconsistent brand and model naming, and the same item often has an official name, a colloquial name and a reference code used interchangeably.

Where the retail reference comes from our archive rather than a live listing — common for discontinued models — that is recorded rather than presented as a current price.

Yes, on the primary side: listings from sellers not on your authorised list, below-retail offers on current-season items, and cross-border price gaps on the same reference.

What we provide is quantified activity by platform and geography. Whether a specific seller is unauthorised depends on your distribution agreements, which we do not see — you supply the authorised list and we compare against it.

Yes, and watches behave differently enough to be worth flagging. Reference numbers are more standardised, which helps matching, but condition and completeness — box, papers, service history — affect price more sharply.

We capture accessory and papers presence where declared, since on watches that can move price by a substantial margin, more than on most other luxury categories.

Ask prices, plus sold and delisted signals where a platform publishes them. Many resale platforms do not publish achieved prices, in which case we do not have them.

Where a listing disappears without a sold indication, we record it as unconfirmed rather than as a sale — the same discipline as our property service. Publicly published auction results are collected where available; subscriber-only price databases are licensed products we do not access.

The resale ask as a percentage of primary retail price for the same item and condition. It is the headline metric in this category because it is the clearest external signal of brand desirability.

Above 100% means an item resells above retail, which happens on scarce models and is a strong desirability signal. Tracking the ratio's trend by model and condition shows desirability developing or fading before it appears in reported results.

Seller type — consignment, platform-owned or peer — and volume concentration signals, as business characteristics. Seller personal details are not part of the deliverable.

For brand protection, the useful unit is the selling operation and its volume pattern, not an individual's identity. The same boundary applies across all our services.

We quote individually. The main driver is whether the primary-to-resale join is required, since matching and condition normalisation are where the work concentrates, followed by brand and platform count.

Resale-only or primary-only collection sits at the lighter end. Full join across many brands and platforms with condition normalisation sits higher. One scoping call, a free pilot on your own brands within 24 hours, then a fixed monthly quote. Request a quote.
