# Look up a batch of Chewy products' structured attributes and handling flags

`GET /chewy/item-attributes`

## Request

- Base URL: `https://api.crawlora.net/api/v1`
- URL: `https://api.crawlora.net/api/v1/chewy/item-attributes`
- Auth: API key in header `x-api-key`

Returns Chewy's own specification table for up to 20 products in one call, keyed by part number -- the structured attribute list (lifestage, pet type, product type, material, made-in country, packaging type, flavor, defining size, plus long-form key-benefits and cautions copy), together with the handling and compliance flags that govern how an item ships (pharmaceutical, prescription vet-diet, frozen, refrigerated, single-tablet, gift card), its bundle structure and component SKUs, its autoship eligibility/discount and preset reorder cadence, its merchandising classification path, and the numeric category group ids it belongs to (each usable directly as chewy_category's group_id). This complements rather than repeats chewy_products and chewy_product: price, rating, images, reviews, and descriptions stay on those endpoints, and the attribute table is not available from either. Use the group parameter to return a single attribute group. Part numbers Chewy does not recognize are reported in not_found; if none of them resolve the response is a 404.

## Query parameters

- `part_numbers` string, required
- `group` 'DEFINING' | 'STANDARD' | 'EXTENDED' | 'HIDDEN'
