/**
 * List the available animation presets along with their perspectives and the eight supported compass directions (N, NE, E, SE, S, SW, W, NW). Synchronous GET with no request body: it returns an animations array (each with id, name, category, description, duration, and preview_url), a deduplicated perspectives array, and the directions list. This is a free discovery endpoint and does not charge credits. Use it to obtain the preset_id, perspective, and direction values that transferMotion needs, and to find motion preset names you can reference when animating; pair it with transferMotion (to apply a preset onto a sprite), animateSprite (text-prompt animation), or animate3DModelPreset (apply any preset by id to a rigged 3D model). Requires an API key (user scope).
 * 
 * GET /assets/sprite/animation-presets
