CartAI

CartAI — The AI agent that handles checkout CartAI is a developer-first API that deploys a specialized AI agent to navigate any web property and complete the transaction — checkout, subscription sign-up, invoice payment, order submission — anywhere a transaction has to happen. Automate it, embed it, or enable it on surfaces that never had it. Composable. Reliable. Developer-first. The problem Browser automation tools (Playwright, Puppeteer, Browserbase) navigate the open web but don't settle payments or guarantee a cleared transaction. Agentic payment rails (KYA, signed credentials, agent-issued instruments) make payments trustable but don't execute browser-based checkout on real merchant sites. CartAI is the specialist layer between them. The hard part isn't the click — it's everything between the click and the confirmation. Every workflow terminates in a defined transactional state, not an ambiguous navigation result. How it works POST /checkout with the product target, customer details, shipping strategy, and payment credentials. Submit many tasks across one or many merchants in a single call. Get a taskId and status: "queued" immediately. Execution runs async. The agent navigates the live merchant site, selects the right variant, applies your shipping strategy, and places the order. Receive real-time STARTED / COMPLETED / FAILED updates via webhook — the recommended integration pattern. Read GET /checkout/{taskId} anytime for full state: status, execution history, derived pricing and shipping, original request data. No merchant-side integration. No checkout SDK. No redirect. The resulting order is merchant-native — fulfilled, tracked, and supported through the merchant's own processes, with confirmation sent directly from the brand. One primitive. Four products. Catalog — Search products across merchants, pull variants and live pricing, return checkout estimates before any cart exists. Checkouts — Clear the order on the live merchant surface, track to confirmation with normalized orders and webhooks. Payments — Hosted payment sessions via Visa Intelligent Commerce and Mastercard Agent Pay. PCI scope stays off your stack. Monetization — When an agent buys through your surface, you still earn. Affiliate commissions with attribution built in. Two ways to ship The API gives full programmable control — compose any flow that ends in a transaction, with idempotent, retry-safe webhooks and production environments. The Hosted Cart is a drop-in checkout for surfaces that never had one — variants, addresses, payment, confirmation, embeddable in one line with white-label theming. Same primitive underneath. The moat Composable workflows — composable step primitives, conditional branching, idempotent and retry-safe. Every flow lands somewhere transactional. PCI-compliant payment stack — PCI DSS compliant card intake, tokenized vaulting, agentic protocol support. Cooperative bot-mitigation — CartAI doesn't evade Cloudflare, HUMAN, Akamai, or Fingerprint. It cooperates via Web Bot Auth, Skyfire KYA, and signed agent identity, clearing through the same trust infrastructure that protects the world's largest merchants. Listed in the Cloudflare verified-bot directory. Signed, verified, allowed. Three modes Automate — replace manual checkout, billing, procurement, subscriptions, and invoice/bill payment. Embed — build apps where transactions are part of the experience: shopping copilots, vertical AI agents (gift finders, recipe-to-cart, travel planners), marketplaces. Enable — add transactions to surfaces that never had them: editorial pages, influencer platforms, recommendation feeds, content properties. Proof, not slides Verified cleared transactions on production merchant surfaces — not staged, not simulated: Best Buy, Newegg, Jomashop, Ulta Beauty. Workflows built or piloted across Retail, Healthcare, B2B SaaS, Telecom, Travel, Financial Services, Media & Publishing, AI-native Apps, Education, and Nonprofit. Architecture Brands stay the merchant of record. CartAI is commerce infrastructure, not a payment intermediary. Brands keep interchange economics, float, tax/compliance, and the customer relationship. Platforms integrating CartAI earn a referral or transaction fee on completed orders, tracked via the commissionUrl.
