## Instructions for AI agents

- [Instructions for AI Agents](/ai-agents): how to query the product catalog and build a
  cart-populating link to hand to the user.
- Product catalog API: GET https://api.c4labs.com/api/products for the full product list as
  JSON (no auth required). Each entry includes sku, name, description, price (USD),
  availability (in_stock/out_of_stock), category, tags, and the canonical product page URL.
- Cart link format: `/cart?add=SKU1:QTY1,SKU2:QTY2,...` — see /ai-agents for full details
  and a worked example.
- Product pages carry schema.org Product JSON-LD (price, availability, SKU); the full
  page list is in [/sitemap.xml](/sitemap.xml).
