Description, as the server wrote it Build a one-tap link that makes a short vertical AI video of a character doing what the user describes (e.g. "Malfoid dances on the castle roof at midnight"). Use this whenever the user asks for an AI video, short, clip, TikTok/Reel/Shorts-style video, or animation of a character, avatar, mascot or persona. Returns a URL on cast.katechon.technology. Give the URL to the user and tell them to open it and tap the button: the video appears on that page, usually within half a minute (a few minutes for a 2-3 character group scene). This tool does NOT generate anything, charge anything or need an account. Live videos require purchased credits; new visitors receive no generation credits. Only characters returned by list_characters are supported premade cast for this flow; other cast members appear on story cards. Longer videos and custom characters cost credits (from $0.99). For a premade character pass character="malfoid" (or "malfoid,leo" for up to 3). For anyone else pass character_name and character_description (their look) instead; the user designs the character before the video.
