Channel3

Channel3 is product data infrastructure for AI shopping. It aggregates catalogs from thousands of brands, structures them into a common format, enriches missing details and keeps them continuously updated, so that AI agents can reliably search, recommend and purchase products. The company reports that its product graph covers more than 100 million products from over 25,000 brands. It serves three audiences. Developers get a single API for product search, browsing, image search, similar product lookup, price tracking and conversational shopping, and can earn commissions on sales. Brands can optimise and sync their catalogs and distribute them to AI and shopping platforms, including Google Merchant Center, Microsoft Merchant Center and OpenAI, through Channel3's merchant tools. Enterprises can add AI shopping to their own products with a conversational agent, search and commissions, with checkout listed as coming soon. Developer pricing is published in the documentation. Every account receives 1,000 free credits a month, and additional credits are billed on use at $0.007 each. Search, browse, image search, similar and lookup calls cost one credit each, conversations cost one credit per turn plus any search credits the agent uses, price tracking costs one credit per product per day, and endpoints for collections, brands, websites, products and categories are free. Bulk pricing is available by contacting the company. Agents without an account can pay per request through the Machine Payments Protocol, with no API key or signup required. Pricing for brand distribution and enterprise deployments is not listed.
