Checkout is the hard part, and most solutions clear it only where the merchant has integrated. CartAI completes checkout on any live merchant surface with no merchant-side work, cooperating with bot detection instead of evading it. One developer-first API, four products: Catalog (search and live pricing across merchants), Checkouts (clear and track orders to confirmation), Payments (PCI off your stack via Visa and Mastercard agent rails), Monetization (commissions on every agent sale).
CartAI is a developer-first API that deploys a specialized AI agent capable of completing transactions on any live web property — from e-commerce checkouts and subscription sign-ups to invoice payments and order submissions. Unlike general-purpose browser automation tools, CartAI is built specifically for workflows where a transaction must actually clear. It operates without requiring any merchant-side integration, cooperating with bot detection systems rather than trying to evade them. The platform offers four core products: Catalog (search and live pricing across merchants), Checkouts (clear and track orders to confirmation), Payments (PCI-compliant processing via Visa and Mastercard agent rails), and Monetization (commissions on every agent sale).
Every transaction has a unique shape — some require shipping details, others need 3DS authentication, and many demand login credentials. CartAI workflows assemble the exact steps your specific situation requires, using composable step primitives and conditional branching to handle any flow while always landing somewhere transactional.
The API operates asynchronously — you submit a checkout task and receive a task ID immediately, then listen for lifecycle events via webhooks. Events like STARTED, COMPLETED, and FAILED let you build robust post-purchase flows, retry logic, and customer notifications without polling or blocking your application.
CartAI can transact through any web property — major e-commerce platforms, custom carts, intranet portals, vendor portals, and login-gated workflows. There's zero merchant-side integration required, and the agent cooperates with bot detection instead of trying to bypass it, making it reliable across diverse surfaces.
"The hard part isn't the click. It's everything between the click and the confirmation."
This quote captures CartAI's core differentiator. While countless tools can navigate websites and fill forms, very few can reliably clear a transaction from start to finish. CartAI engineered three critical pieces — composable workflows, payment processing via Visa and Mastercard agent rails, and PCI compliance off your stack — into a single primitive designed for that single, non-negotiable outcome. It sits at the specialized intersection of browser automation and agentic payments, solving the problem neither category addresses alone.
You're building AI agents that need to complete real transactions on behalf of users, or you're tired of maintaining brittle browser automation scripts that break every time a merchant updates their checkout flow. CartAI is especially valuable if you need to transact across multiple merchants without negotiating individual integrations, or if you want to add checkout capabilities to surfaces that currently lack them entirely.
