Amazon SP-API · getCatalogItem · GET /catalog/2022-04-01/items/{asin} This returns what Amazon ACTUALLY DISPLAYS, not what the seller submitted. Amazon merges data from all sellers and its own sources, then picks the winning value for each attribute (title, images, bullets, brand, etc.). To check whether Amazon kept a seller's submission, compare data.item.attributes with listings_getListingsItem's data.attributes.

## Arguments

| Name | Type | Required | Description |
|---|---|---|---|
| `store` | string | yes | the store ref `<store>-<CC>` (name-country, e.g. 'myStore-US') — one of get_user_context's store_refs, verbatim. |
| `asin` | string | yes | the ASIN (e.g. 'B0XXXXXXXX'). |
| `includedData` | string[] |  | List of additional data to include in response. Default: ['summaries'] (basic info only). NOT supported here: 'customerReviews' (use customerFeedback_getItemReviewTopics), 'offers' (use Product Pricing API → productPricing_getItemOffersBatch). Recommended: ['attributes', 'images', 'dimensions', 'salesRanks'] for full details. Allowed: attributes \| classifications \| dimensions \| identifiers \| images \| productTypes \| relationships \| salesRanks \| summaries \| vendorDetails. Allowed: attributes \| classifications \| dimensions \| identifiers \| images \| productTypes \| relationships \| salesRanks \| summaries \| vendorDetails. |
| `locale` | string |  | Locale for localized content (e.g. 'en_US', 'fr_CA'). |

## Result

- `data.asin` — the requested ASIN.
- `data.item` — catalog item object with: - asin: Amazon Standard Identification Number - summaries: basic info (title, brand, manufacturer, etc) if includedData includes 'summaries' - attributes: detailed attributes (color, size, material, etc) if includedData includes 'attributes' - images: product images with URLs if includedData includes 'images' - dimensions: package dimensions (weight, height, width, length) if includedData includes 'dimensions' - identifiers: all product identifiers (EAN, UPC, ISBN, etc) if includedData includes 'identifiers' - productTypes: product type info if includedData includes 'productTypes' - relationships: parent/child relationships (variations) if includedData includes 'relationships' - salesRanks: sales rank by category if includedData includes 'salesRanks' - classifications: the browse-node hierarchy per marketplace if includedData includes 'classifications' — [{marketplaceId, classifications: [{displayName, classificationId, parent: {displayName, classificationId, parent: …}}]}]. Amazon retired the v0 categories operation on 2026-03-31; this is the category hierarchy (a classificationId is a browse node id). - vendorDetails: vendor-only data if includedData includes 'vendorDetails' (vendors only)

## Workflow

- 1. Use catalogItems_searchCatalogItems to find ASINs of interest. 2. For up to 20 ASINs at once use catalogItems_searchCatalogItems with identifiers + identifiersType ASIN (same per-item shape); call this tool for a single ASIN.
