CartAI is a developer-first API and MCP server that deploys a specialized AI agent to navigate any web property and complete transactions—checkout, subscriptions, invoices, and orders—reliably and securely.
The AI agent that handles checkout.
- Automating checkout flows on any merchant website
- Subscription sign-up, plan changes, and cancellations
- Invoice payment and order submission
- Building vertical AI apps like gift finders, recipe-to-cart, or travel planners
- Enabling checkout on surfaces that previously lacked it
- Sign up for CartAI and obtain your API key.
- Integrate the CartAI API into your application or workflow.
- For agent-based setups, plug in the CartAI MCP server into your MCP host (e.g., Claude Desktop, Cursor).
- Compose your transaction workflow using step primitives (search, estimate, checkout).
- Deploy and monitor transactions via webhooks for every state transition.
