Input reference

Creates a web monitor. mode is the constant web. The behavior is described by target (page, sitemap, or extract) and change_detection (exact or semantic). Supported combinations: page + exact, page + semantic, sitemap + exact, extract + semantic. change_detection is optional. page targets with instructions infer semantic detection, while page targets without them infer exact detection. Other targets default to their supported detection type. schedule is optional and defaults to once per day.
