# Channel3

Channel3 is product search and agentic commerce infrastructure for developers, AI shopping agents, recommendation systems, and brands that want AI-ready product catalogs.

## Primary Pages

- [Channel3 home](https://trychannel3.com/): Agentic commerce infrastructure.
- [Channel3 for Developers](https://trychannel3.com/developers): Product data API for AI shopping apps, ecommerce recommendations, visual search, and agentic commerce.
- [Channel3 for Brands](https://trychannel3.com/brands): Make product catalogs discoverable and usable by AI shopping agents.
- [Product Search API](https://trychannel3.com/products/api): Product search API for ecommerce recommendations and AI product discovery.
- [Product category API pages](https://trychannel3.com/product-search-api/apparel): Programmatic category pages for product search API use cases.

## Product Data Pages

- [Brand directory](https://trychannel3.com/product-data/directory): Browse brands with deep catalogs available through the Channel3 product data API, paginated A–Z.
- [Brand product data pages](https://trychannel3.com/product-data/brands/nike): Per-brand product data — sample products, price ranges, catalog size, and API examples. Pattern: /product-data/brands/{slug}.
- [Category product data pages](https://trychannel3.com/product-data/fashion): Per-category product data and top brands. Pattern: /product-data/{category} (e.g. fashion, beauty, electronics, home-and-garden).

Provenance & freshness: product data is aggregated across merchants and refreshed daily. A brand is indexed and internally linked when it has a deep catalog (800+ products) OR demonstrated search demand; a small set of adult/mature brands is excluded for brand safety. This keeps the indexed surface high-quality.
