  "accessNotes": "Yuyu-tei is one of Japan's largest single-card shops; its sell pages are public, server-rendered and need no login or JS. robots.txt only sets Crawl-delay for Slurp/bingbot/AhrefsBot/serpstatbot and lists a sitemap (which 404s); nothing is disallowed for other agents. Per game (poc Pokémon, opc One Piece, ygo Yu-Gi-Oh! OCG, ws Weiss Schwarz, digi Digimon, dm Duel Masters, ua Union Arena, vg Vanguard, bs Battle Spirits, gcg Gundam) we read the game top page https://yuyu-tei.jp/top/<game> once to list the expansion codes and names (the `vers[]` checkboxes), then one page per expansion https://yuyu-tei.jp/sell/<game>/s/<ver> which lists every single of that expansion grouped by rarity (number, Japanese name, sell price in JPY incl. tax, stock count, card image). Incremental runs cover the newest `setsPerGame` expansions per game; backfill walks all of them. Requests are spaced ≥ 4 s, 1 concurrent, honest UA. Not fetched: buy-list (買取) prices, damaged-card pages (/s/damage), member/cart pages, card detail pages (only linked). Prices are shop asking prices → listings, never sales; the shop is the seller (no personal data).",
