Checkout semantics

Checkout semantics uses Smart DOM Trees and AI agents to understand the functional meaning of e-commerce elements regardless of underlying code changes.

Checkout semantics shifts automation from fragile CSS selectors to intent-based navigation. By utilizing Smart DOM Trees, the system identifies that a button labeled Buy Now or a cart icon serves a specific transactional purpose, even if the site's front-end framework or class names change. This technology powers agentic commerce by allowing AI sub-agents to handle multi-step flows, CAPTCHA solving, and 3D Secure verification across thousands of unique merchant sites at an average cost of $0.12 per task. It effectively eliminates the 20% to 30% failure rate common in traditional Puppeteer or Playwright scripts by focusing on the structural logic of the checkout process rather than brittle pixel positions.
