CPG category share-of-shelf Canada
“Check the availability index for Dove in the beauty category in Canada and break it down by seller — I want to know where they have the strongest shelf presence.”
Category-root availability comparison

Technical details
Endpoint
POSThttps://api.syntalic.com/v1/marketing/availability-index?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quantitative measure of a brand's retail availability or share-of-shelf across sellers or category segments. It is distinct from price positioning (which compares price tiers) or promo intelligence (which tracks discounts) — this specifically indexes how widely a brand's products are stocked. Prefer it over the analyst-level or social signals endpoints when the user's question is about physical/digital retail presence and distribution breadth rather than pricing or sentiment.
Side effects

- Brand not found in catalog — may return empty index or zero values
- Unknown or unresolvable category string — no matching products found
- Payment failure (x402) — request rejected before processing
