CartAI

CartAI provides a programmable transaction primitive: an AI agent plus browser execution and payment infrastructure designed specifically to ensure transactions clear on live merchant surfaces. It targets developers and teams who need reliable, repeatable checkout automation across any web property—e-commerce checkouts, custom carts, vendor portals, login-gated workflows, subscriptions, invoice payments, and procurement flows. The offering includes a Checkout API with asynchronous execution and webhooks, an open-source MCP server for agent integrations, and a drop-in Hosted Cart for embedding checkout into surfaces that never had one.

Key Features

Programmable, composable workflows

Workflows assemble the steps your specific situation requires (shipping, 3DS, login, etc.) with composable step primitives, conditional branching, and idempotent, retry-safe execution.

Checkout API & Webhooks

One API to deploy agents that navigate web properties and complete transactions, with async task execution and webhooks for every state transition (STARTED, COMPLETED, FAILED).

PCI-compliant payment stack

Card intake, vaulting, and agentic protocols with PCI DSS compliant intake, tokenized card vaulting, and hosted payment sessions to keep PCI scope off your stack.

Cooperative bot-mitigation & identity

Cooperates with trust infrastructure rather than evading it — Web Bot Auth signed identity, Skyfire KYA integration, and compatibility with Cloudflare / Human / Fingerprint protections.

Multiple deployment modes

Three ways to ship: API for full control, CartAI MCP server for agent hosts (open source, Apache 2.0), and a Hosted Cart drop-in component or iframe for turnkey embedding.

Catalog, Payments, Monetization products

Complementary primitives: Catalog for product search and estimates, Payments for hosted sessions (Visa Intelligent Commerce and Mastercard Agent Pay), and Monetization for affiliate commissions and attribution.

Use Cases

Automate existing transactional processes

Replace manual checkout, billing, and procurement flows with reliable, programmable execution across e-commerce, subscriptions, invoices, vendor portals, and B2B procurement.

Embed transactions into new applications

Build apps where transactions are part of the experience—agents, copilots, vertical AI tools, marketplaces, and digital product flows with integrated checkout.

Enable transactions on surfaces that never had them

Add direct checkout to editorial pages, influencer platforms, content sites, recommendation feeds, and other discovery surfaces to convert intent in place.

Integrations

Visa Intelligent Commerce

Used for hosted payment sessions to keep PCI scope off your stack (Payments product).

Mastercard Agent Pay

Supported as part of hosted payment sessions and agentic payment capabilities.

Skyfire KYA

Integration for cooperative bot-mitigation and agent trust (KYA integration).

Web Bot Auth / Cloudflare / Human / Fingerprint

Works cooperatively with common bot-mitigation and fingerprinting systems to clear transactions without evasion.

MCP host integrations (Claude Desktop, Code, Cursor, VS Code)

MCP server plugs into agent hosts such as Claude Desktop, Code, Cursor, and VS Code to enable autonomous checkout by agents.

Benefits

Higher transaction completion reliability by focusing on the end-to-end clearing of payments on live merchant surfaces.
Flexible, composable workflows that handle varied transactional shapes (shipping, authentication, 3DS, login, etc.).
Reduced PCI scope and integrated payment sessions via hosted payments and tokenized vaulting.
Preserves attribution and monetization with built-in affiliate and commission support.
Multiple integration modes (API, MCP server, Hosted Cart) to fit developer and product needs.

Limitations

Specialized for transactional workflows: CartAI is built specifically for workflows where a transaction must clear and is not designed for general-purpose non-transactional browser automation.
