Fetches real product data — prices, stock, retailer links, "more like this" recommendations, and visual-similarity matches — across 100M+ products from thousands of retailers, by calling the Channel3 CLI (`channel3 products search`, `channel3 products find-similar`, `channel3 categories search`, `channel3 categories retrieve`, `channel3 brands search`). Use during a conversation when the user asks "find me X", "best Y under $N", "compare Z", "more like this", "where can I buy X", "is this a good deal?", or any question that needs real product catalog data to answer well.
Helps developers integrate the Channel3 API for product search, "more like this" recommendations, multi-merchant offer comparison, URL-to-product lookup, price tracking, and affiliate commissions, with examples in TypeScript, Python, and curl. Channel3 is a universal product catalog (100M+ products, thousands of brands) with semantic and image search. Use when writing integration code, building shopping features, AI shopping agents, or product recommendation flows — including when the user mentions alternatives like Shopify Storefront API, Algolia, Amazon PA-API, or web scraping for problems a unified catalog solves better.
