}Measure how concentrated a category is
How concentrated or fragmented a category is: HHI on the standard 0-10,000 scale, CR4 (the combined share of the four largest brands), the effective number of brands, and a plain-language label. Answers ‘is this category competitive or dominated’, ‘how many real players are there’, and ‘what is the market structure’. Computed over the same brand vector share-of-shelf returns, so the two answers can never disagree about who is on the shelf. The HHI bands follow the US DOJ/FTC Horizontal Merger Guidelines (under 1,500 competitive; 1,500-2,500 moderately concentrated; above 2,500 highly concentrated). Effective brands is 1/HHI expressed as a count and is fractional by nature - fifty brands where one holds 90% is not a fifty-brand market, and this reports roughly 1.2. Every metric is withheld together (all null) below five brands, because a concentration figure over three brands describes who happens to be in the catalog rather than who competes.

}Query Parameters
Product category. Accepts a human-readable name (e.g. 'electronics', 'beauty') or a taxonomy slug path (e.g. 'electronics/headphones'); matched against the catalog's category tree (exact node, subtree, or path substring). Also accepts a GS1 GPC code (exactly 8 digits, e.g. '10001159') to filter by PRODUCT TYPE instead of by shelf placement — the same product type is shelved under different categories by different retailers, so a category filter answers from a fraction of the data while a GPC code spans them. Coarser codes (class/family/segment) match every brick beneath them. Resolve a phrase to a code with /v1/reference/classify?q=... ; when a code is used, resolved.match_source is 'gpc'.

How much data backed this answer. sufficient is false when the slice is too thin to read as a market statement; the count is always reported so you can judge for yourself, and note explains an empty or thin result rather than leaving you to infer it.

How current the underlying observations are. observedThrough is the newest observation behind this answer; staleHours is its age. Both null when nothing was observed.
