Recheck1–20 known Yahoo!Shopping Japan store product URLs for public asking price, source ordering flags, delivery inventory labels and every on-page SKU/size/color option. One product observation with nested variants per URL. Save a watchlist Task for repeated imports by sellerCode/sourceItemId; no search, market statistics, transaction prices or physical-stock guarantee.

Price: $0.003 per delivered product observation.

Input

itemUrls:1–20canonical HTTPS URLs exactly https://store.shopping.yahoo.co.jp/{store}/{item}.html, no query/fragment/port/userinfo. Input duplicates free and removed in order. Single,1axis,2axis and3axis products supported up to1000sourceSKU rows each; extra related-color product links are not fetched or merged. Unknown axes/oversized/missing/mismatched SKU identity fail visibly rather than truncate.

Output

One yahoo_shopping_product_observation row: canonicalUrl, URL-derivedsellerCode, sourceItemId(srid), sellerManagedItemId, short title, priceJpy(applicablePrice), source taxExcludedPriceJpy|null, currencyJPY, janRaw|null, sourceIsOnSale/sourceIsAvailable/sourceIsPreOrder/sourceIsUsed, deliveryInventoryLabel|null, stockText, axisCount,variantCount,variants,fetchedAtUTC. Variant rows contain originalskuId,1–3axisName/choiceName pairs, sourceIsAvailable, sourceStockText/sourceStockSymbolType and variantPriceJpy|null. For3axes, variantPriceJpy is source individualItem.price.applicablePrice; for1/2axes it is choice.price. Null variantprice stays unknown; never inherit rootprice silently. Source ordering true can coexist with お取り寄せ or 入荷待ち and is not immediate shipment. No physical quantities, future stock alerts or actualpaid-price claim. JAN is raw/unverified, not a unique size identifier. No missing-price0 guess.

Pricing

USD0.003 product-observed per complete delivered unique product including all nested variants, no startup/search/SKU fee. Source-confirmed unavailable product with valid price is a useful paid observation. HTTP404/access/429/challenge/unknownstructure fail without a negative observation; allsourcework stages before any atomic charged delivery. Platform spending allowance limits input prefix before acquisition, ChargeResult must equal delivered count. SUMMARY/RUN-SUMMARY report paid deliveredRows.

Limits

21HTTPrequests including robots,180seconds,256MB,4MiBwire/8MiBdecoded perresponse and64MiBtotal,24MiBstagedoutput cap; samehost serialstarts>=2seconds or applicableactualUArobotsdelay. Fixed product host/path, redirect rejection, no cookies/privateaddresses/browser/proxy/login/paidAPI.20products/1000SKUs are hard safety caps, no all-store or all-market coverage claim.

Privacy and source conditions

Only typed source facts and short product/option labels. No descriptions/photos/media/reviews/customerpersonalization/individualsellerprofiles/contact data/HTML snapshots. On-demand only, source attribution retained. Applicable LYterms prohibit data reuse beyond intended purpose and some unapproved commercial behavior; these are recorded contractual risks under existingDR-0007, not permission. Current linked terms and free public/seller API differences are recorded in the scout.

Complete SKU CSV export

Raw JSON retains nested variants plus a complete equivalent variantsJson string. Parse variantsJson as JSON to recover every SKU and field. Use ?format=csv&view=overview: all variants remain in one text cell, avoiding the platform2000column flattening cap for large matrices. No field truncation or extra SKU fee.

Measured source boundary

A current ordinary search sample included a product with source axisNum=3. The initial0–2axis parser rejected it as unsupported-axes before charged delivery. Current3axis support binds individualItemList SKU IDs, option names/choices, source variant applicablePrice and stock flags to individualItemOptionList definitions and the complete skuIdList key/choice map. The original20URL collection is rerun without excluding this product. More than3axes, unknown/missing/duplicate mappings or over1000SKUs still fail. This observation is not a market-wide coverage estimate. Empty source janCode is retained as an empty raw identifier; it is not a verified JAN.
