Give an agent hands on the live web
Not every system has a clean API — sometimes an agent has to operate a real web page. This category gives it browser control: navigate, click, type, scroll, take a snapshot, extract structured content, and capture screenshots — plus PDF text extraction for documents on the web. For systems that do expose an API, an agent can call it directly with API Invoke, OpenAPI Invoke, webhook triggering, and RSS fetching. So whether or not a target has an interface, an agent can reach it.
