KOMEHYO Rolex Inventory & Asking Price Monitor

Track exact Rolex references in KOMEHYO Japan inventory for dealer watchlists and sourcing research. Each run returns stable product IDs, current JPY asking prices, explicit stock status, condition rank, box/warranty evidence and the published warranty date. Supply selected observations from an earlier run to see same-ID price and stock changes. Optional Daikokuya buyback context supplements this inventory snapshot.

Input

references accepts 1–10 exact Rolex reference codes: five or six digits with an optional suffix of up to four uppercase letters. Duplicates are removed before acquisition and billing. maxListingsPerReference defaults to 10 and accepts 1–50. maxTotalListings defaults to 50 and accepts 1–100; it must cover at least one detail per distinct reference. The total detail budget is divided evenly before acquisition, with any remainder assigned in input order. Unused quotas are not redistributed.

{"references":["126610LN","126500LN","16233"],"maxListingsPerReference":10,"maxTotalListings":30,"includeBuyback":false}

includeBuyback defaults to false, an intentional change from the previous condition-screen-only contract. Set it to true to acquire Daikokuya’s dated mail-in reference table and apply its advertised eligibility requirements. maxBuybackAgeDays defaults to 7 and accepts 1–30; it only affects qualified buyback gaps.

previousListings optionally accepts up to 100 selected baseline observations:

{"references":["126610LN"],"previousListings":[{"reference":"126610LN","listingId":"230-000-857-0603","askingPriceJPY":2400000,"stockStatus":"in_stock","checkedAt":"2026-10-02T00:00:00Z"}]}

Every baseline row must have exactly those five fields: a configured exact reference, a stable KOMEHYO product ID, a positive integer JPY asking amount, in_stock or sold_out, and an ISO observation timestamp with timezone strictly earlier than this run. Duplicate reference/ID pairs, unknown fields, arbitrary URLs and credentials are rejected. Baseline history is supplied by you and is not independently verified. The platform event budget caps distinct references before network work; zero event budget fails before acquisition.

Output

One japan_watch_retail_buyback_comparison_summary row per acquired reference preserves the existing row type and adds the primary inventory workflow:

• status: inventory_available, no_exact_in_stock_listing, or no_retail_listing. Optional buyback eligibility does not change this result.
• inventoryCount, minAskingPriceJPY and maxAskingPriceJPY: exact-reference, explicitly in-stock facts in the acquired detail sample. Asking prices are not sold prices or valuations.
• listings: stable product IDs, URLs, independently verified detail reference, asking price, stock, condition rank, tri-state accessories, warranty date with its actual precision and interval, and manufacture year only if published. A warranty date is never relabeled manufacture year.
• snapshotComparison: same-reference/same-ID price or explicitly observed stock changes against your baseline, with separate baseline/current timestamps. newlyObservedListingIds means absent from that supplied baseline; it does not assert a new listing. unobservedBaselineListingIds never means sold or removed.
• retailReportedCount, sampledListingCount, truncated, sampleOrder and coverage: the search hit count and actual acquisition boundaries. Keyword hits are not an exact-reference inventory population count.
• buybackStatus: not_requested by default; when enabled, dated exact-reference rows and eligibility exclusions remain separate from current retail inventory.

KOMEHYO searches use ascending asking price, and only the first page is sampled. Up to 50 details per reference and 100 total can be acquired. There is no all-stock, global-market, population-minimum or complete-change-feed claim. Wrong-reference keyword hits and sold-out details are visible but excluded from inventory counts and sampled price bounds. A source-declared zero or no exact in-stock detail is a useful watchlist negative only after the source structure is valid.

Ordinary used inventory is useful even when buyback comparableCount is zero. For example, the observed 126610LN offers at JPY 2,350,000 and 2,420,000 have warranty months 2021-11 and 2025-11. They remain stock/asking-price observations even though neither meets Daikokuya’s recent-warranty condition. The supplied example demonstrates a JPY 50,000 same-ID decrease against a synthetic user baseline; it is not independently measured historical pricing.

Optional buyback conditions

A conditional gap requires a unique supported exact table variant, a fresh table, a supported used/unused condition, complete age-appropriate accessories, a latest dated warranty card, and every advertised condition affirmatively supported. The full possible warranty date interval must fall inside the past six calendar months for used or one month for unused and must not extend into the future. Rank A/S or box plus warranty alone does not prove those requirements. Used 〜 prices retain upper_bound; inquiry amounts remain null. Unknown facts, ambiguous variants and stale tables suppress only the conditional gap. Actual dealer acceptance, condition, authenticity, shipping, fees and payment remain unverified.

Limits and charging

HTTP only, 256 MB, no required external API, proxy or browser. Fresh robots checks precede each requested host. Maximum 113 requests: one KOMEHYO robots read, 10 reference searches, 100 details, and optionally one Daikokuya robots read plus its table. Each request has a 30-second timeout and 1 MiB body cap; acquisition has a 300-second deadline. Same-host request starts are at least 1.5 seconds apart or slower when robots requires it. No retries, redirects, arbitrary routes, account/cart actions or transactions.

Access blocks, rate limits, timeouts and structure changes are explicit errors. All requested source acquisition is staged before delivery; any upstream failure emits no partial rows or billable event. A requested buyback source failure fails the run; leaving it disabled avoids that extra dependency. One charged dataset push per completed reference snapshot uses the existing comparison-created event once, including verified watchlist negatives. No per-detail event or manual-plus-push double charge. The price is $0.02 per snapshot. No actor-specific free trial is promised; platform credits may apply.

Privacy

Return selected public product/reference facts only. Exclude images, free descriptions, customer/contact data, serial numbers, raw tables/HTML, cookies and tokens. Source bodies are not logged or persisted. Fixtures contain selected non-personal facts and synthetic fault cases. Baseline input is strictly limited to product observations.
