Channel3

Channel3 is a developer-facing API and infrastructure platform for what it calls agentic commerce, AI agents that search, recommend, and help complete purchases rather than humans browsing a storefront directly. The core product is a product data API giving access to hundreds of millions of items across more than 25,000 brands, with real-time pricing, availability, and structured attributes intended to make it easy to build shopping features into an app, chatbot, or autonomous agent. Developers can integrate with the API directly using TypeScript or Python SDKs, or connect through an MCP server aimed at AI agent frameworks, which offers a free tier of 1,000 searches per month with no API key or credit card required. On the brand side, Channel3 lets companies distribute their catalogs so their products become discoverable and machine-readable to AI shopping assistants, rather than only indexed for traditional search engines. Every product returned through the API includes a trackable link, and Channel3 handles attribution, routing, and payouts, letting developers earn commissions when their agents drive a sale. Coverage currently centers on the US market, with the company describing international expansion as a work in progress, and Channel3 states it is still pursuing SOC 2 and GDPR compliance certifications rather than already holding them.
