CartAI
CartAI
API for a specialized AI agent that navigates any web property and reliably completes checkouts, subscriptions, invoices, and orders.
Key features
- Composable Transaction Workflows: Assemble the specific steps a flow requires — shipping, 3DS, login, coupon — while always landing on a cleared transaction.
- PCI-Compliant Payment Stack: Built-in card handling and payment execution so cards never touch your servers and transactions actually clear.
- Idempotent, Retry-Safe Execution: Every step is designed to survive retries without double-charging or partial orders, with conditional branching for real-world edge cases.
- Universal Web Coverage: Runs against any web property — e-commerce checkouts, custom carts, intranet portals, vendor portals, login-gated flows.
- Async API with Webhooks: A single POST /checkout returns a taskId; STARTED, COMPLETED, and FAILED webhook events keep your app in sync with agent progress.
- Payment and Shipping Profiles: Reusable buyer, card, and shipping profiles let one API call target arbitrary product URLs across sites.
Best for
- Embedded Checkout in AI Apps: Give a chat or agent product the ability to actually buy the item it just recommended, without building site-specific integrations.
- Automated B2B Procurement: Have an agent submit orders and pay invoices across dozens of vendor portals with different login and PO flows.
- Subscription Sign-Up Automation: Programmatically enroll users into third-party subscriptions when a first-party API doesn't exist.
- Retail Price-Trigger Buying: Auto-execute purchases the moment a monitored product hits a target price or restocks on any supported site.
- Agent-Driven Bill Pay: Let agents pay recurring invoices on portals that require login and manual navigation.
