Developers use the Channel3 API to build AI shopping apps and agents — recommendation engines, visual search, autonomous purchasing agents, and more. Channel3 gives you a access to hundreds of millions of products with prices, availability, structured attributes, and commissions.
Channel3 supports locale-aware search for physical products, starting with the U.S. and expanding across select international markets. Coverage outside the U.S. may be limited at first. Please contact us if you’re looking for a specific geography.

Get started in minutes

Already using Claude Code, Cursor, Codex, or another AI coding agent? Install the Channel3 API skill and let your agent handle the integration for you. Step 1 — Install the Channel3 API skill: 
npx skills add channel3-ai/skills --skill channel3-api
Step 2 — Add UI components (React + shadcn only; skip if you’re not building a UI): 
npx shadcn@latest add https://ui.trychannel3.com/r/all.json
Step 3 — Prompt your agent: 
Build a shopping experience using the Channel3 skill, Channel3 SDK, and Channel3 provided UI components/hooks. Top: text and image search with filters. Show results in a grid; clicking a product opens a PDP with variant selection, similar products, and a way back to the grid.
Your agent now has accurate knowledge of the Channel3 API and will produce working code right away. For a simpler integration without UI components, try: Help me integrate Channel3 into my project using the Channel3 API skill.
