What is CartAI?

CartAI is a developer-focused API that deploys specialized AI agents to navigate any website and complete transactions. Instead of building custom automation for checkout flows, you send a single API request with customer details, product targets, and payment profiles, and CartAI handles the rest—navigating the page, filling forms, and submitting the transaction. It’s designed specifically for workflows where a transaction has to clear, not for general browsing or scraping. The platform supports both sandbox testing and production execution, with async webhook notifications for lifecycle events like start, completion, or failure.

Application scenarios

  • E-commerce checkout

    Automate purchasing on sites like Best Buy, including variant selection (e.g., color) and shipping preferences.

  • Subscription sign-up

    Handle recurring registration flows on any web property with login-gated or multi-step forms.

  • Invoice payment

    Submit payments through vendor portals or intranet systems that require navigation and form entry.

  • Order submission

    Complete order forms on custom carts or legacy systems that lack modern APIs.

  • Login-gated workflows

    Transact on sites that require authentication before reaching the payment step.

  • Vendor portal operations

    Automate procurement, billing, or account management on third-party supplier portals.

Core Features

  • Single API endpoint

    Send a POST request to `https://api.cartai.ai/checkout` with customer, task, and payment data to initiate a transaction.

  • Async execution with webhooks

    Receive real-time events (`STARTED`, `COMPLETED`, `FAILED`) via a webhook listener to trigger post-purchase flows or retries.

  • Sandbox mode

    Test transactions without real money using the `sandbox: true` option in the request body.

  • Variant and shipping support

    Specify product variants (e.g., color) and load shipping/payment profiles from JSON files for each task.

  • Any web property compatibility

    Works across e-commerce sites, custom carts, intranet portals, vendor portals, and login-gated workflows.

  • Developer-first design

    Uses standard REST API patterns with Bearer token authentication and JSON payloads, plus TypeScript code examples.

  • Task queuing

    Each request returns a `taskId` and `status` immediately, then runs asynchronously in the background.

Target users

CartAI is built for developers and engineering teams who need to automate transaction workflows on third-party websites. It’s ideal for SaaS companies building checkout automation into their platforms, operations teams managing vendor or intranet payments, and any developer integrating agentic payment capabilities into their own applications.

How to use CartAI?

  1. Sign up at cartai.ai and obtain an API key.
  2. Send a POST request to https://api.cartai.ai/checkout with a JSON body containing customer details, task targets (product URL, variant, shipping/payment profiles), and optional sandbox mode.
  3. Set up a webhook endpoint to listen for STARTED, COMPLETED, and FAILED events, and handle each accordingly (e.g., notify customer, send post-purchase flow, or retry on failure).
  4. For production, remove the sandbox flag and use real payment profiles. Full documentation is available at the official site.

Effect review

CartAI fills a narrow but critical gap between general browser automation and payment infrastructure. By focusing exclusively on transactions that must clear, it avoids the complexity of general-purpose web automation tools while providing a reliable, composable API for checkout, subscriptions, and invoices. The async webhook model and sandbox mode suggest a production-ready design, though real-world reliability will depend on how well the agent handles site-specific quirks (e.g., CAPTCHAs, dynamic forms). For developers tired of maintaining brittle scraping scripts for payment flows, CartAI offers a promising, specialized alternative—but its true value will be proven by how consistently it completes transactions across diverse web properties.
