  "accessNotes": "Ader (Paris, sales at Hôtel Drouot) runs on the Drouot 'site générique' platform. Public pages read: /ventes-passees?year=YYYY (past sales of a year: title, 'jeudi 09 juillet 2026 à 14h00', venue, /catalogue/<id> link — sales without an online catalogue are skipped) and /catalogue/<id>?offset=N&max=50 (lot cards: number, title, description, cdn.drouot.com image, 'Estimation : 150 - 200 EUR', 'Résultat : 1 081 EUR'; unsold lots have no result). Each page states 'Résultats avec frais' — we read that note per page/lot and set buyer_premium_included accordingly (true for Ader; never assumed, stays null when the note is missing). robots.txt disallows only /recherche/*; CGV contain no clause on automated access (they define 'prix marteau' vs fees). Years 2004→today available for backfill (one index request per year). 2.5 s politeness; salesPerRun caps incremental runs. No login, no bidder data.",
