CartAI is an agentic commerce platform built to complete transactions on behalf of users. It provides APIs for product search, checkout, payment sessions, and monetization so teams can move from discovery to confirmation through a single transaction-oriented flow.
The product is aimed at workflows where a purchase, subscription sign-up, invoice payment, or order submission must actually clear. CartAI runs on the merchant's live site today and also describes support for commerce protocols as merchants expose them, with webhooks used to track the task through completion.
