Shopping, purchasing, and transactional workflows, built into any experience.
CartAI is the API that adds product discovery, checkout, and payments to the experiences you already provide to your customers.
A specialized layer at a specialized intersection.
Browser automation and agentic payments are both vast, important categories. Neither is built specifically for the workflows where a transaction has to actually clear. CartAI is.
Browser automation
Agentic payments
Both adjacent categories solve real problems. CartAI solves the one between them: the transaction has to clear. A specialist primitive built for that single, non-negotiable outcome.
One integration. Transactions that actually clear.
Building across merchants means navigating different catalogs, carts, checkout flows, payment requirements, and trust infrastructure. CartAI handles that complexity behind a single API, so you can build the experience you want without building and maintaining individual merchant integrations.
Built for the way you work.
CartAI adapts to the products, purchasing flows, and requirements of your business, so you can use the capabilities you need without forcing customers into a predefined journey.
- Flexible workflows
- Configurable capabilities
- Reliable execution
Payments, handled securely.
CartAI provides secure payment collection and vaulting, with support for emerging agentic payment protocols, so you can enable purchasing without taking on the underlying payment infrastructure yourself.
- PCI-compliant
- Tokenized payments
- Agentic payment protocols
Built to transact across the web.
CartAI works with the trust and bot-management infrastructure used by major merchants, enabling legitimate automated transactions to be identified and processed rather than blocked.
- Signed agent identity
- KYA
- Bot-management integrations
One API. Four powerful capabilities.
Choose the capabilities your experience needs. From product discovery and checkout to payments and monetization, CartAI gives you the building blocks to create the experience that works for your business.
Signed, verified, allowed. CartAI operates inside the trust infrastructure, not around it.
Build it in, plug it in, or drop it in.
Your team chooses the depth. Integrate the API directly, connect the MCP server to an existing AI agent, or embed the hosted cart with no development at all. Every path runs on the same platform.
CartAI API
The full programmable-transaction primitive. Payments, Orders, Workflows. Compose any flow that ends in a transaction.
- Webhooks for every state transition
- Idempotent, retry-safe by design
- Production environments
CartAI MCP
Plug CartAI into any MCP host. Your agent gets tools to search products, estimate cost, run secure payments, and execute checkouts autonomously.
- Claude Desktop, Code, Cursor, VS Code
- Async checkout with status tracking
- Open source, Apache 2.0
CartAI Hosted Cart
Drop-in checkout for surfaces that never had one. Variant selection, addresses, payment, confirmation — embed it in one line. Same primitive underneath; the transaction still clears the same way.
- Drop-in component or iframe
- Variants, addresses, payment built in
- White-label theming
- Powered by the same API underneath
Automate, embed, or enable.
Every CartAI use case maps to one of three modes — replace a manual transactional process, embed transactions into a new application, or add transactions to a surface that never had them.
