Retailers
In short
Retailers sell the goods an agent buys and set their own terms for agent access. Etsy and Instacart sell inside ChatGPT, Target sells through Google and Wayfair has announced UCP checkout there, Chewy and The Home Depot publish UCP profiles, and Amazon and eBay restrict agents by contract. Policies differ sharply from one retailer to the next.
