Catalogue of the video models behind this server with their status, modes, limits and credit prices. Two models today: craftstory-2 (a talking video of any length from one photo plus an audio clip; 8-15 min) and minimax-h3 (a clip of up to 15 s from one photo, either description-driven with generated sound or audio-driven with lip-sync; 1-3 min). Call this first when unsure which model fits, or to check that a model is not paused.

Library voices (id, name, language, gender) usable as voice_id in create_audio_clip. With include_cloned=true also returns the account's own cloned voices, usable as voice_user_id. Voices are cloned in the CraftStory app, not via the API.

Custom avatars trained in the CraftStory app that craftstory-2 can generate with (pass an id as avatar_id). Each avatar may carry a default voice {id, voice_kind}: voice_kind 'user' means send it as voice_user_id, 'library' as voice_id in create_audio_clip. Pass avatar_id to list that avatar's scenes; a scene id can replace the photo (scene_id) in create_craftstory2_video.

The soundtrack every video model takes as input. Either text (up to 2000 characters) plus exactly one voice (voice_id from list_voices, or voice_user_id for a cloned voice), or file_path to upload a local WAV/MP3/M4A recording. Returns the clip id; it is ready when wait_for_job(model='audio-clip') reports done (usually seconds). Longer scripts: create several clips and pass all ids to create_craftstory2_video in order.

Credits a craftstory-2 job would cost for the given audio clips and settings, without creating anything. Rate per second of audio: 480p 2.2 (2 with lipsync_mode=empty), 720p 3.3 (3 with empty); rounded up per job. MiniMax H3 is a flat 3.3 credits per billed second.

Start a craftstory-2 generation: a photo of a person (image_url or image_path, or a custom avatar scene via scene_id) speaks the given audio clips with lip-sync, gestures and natural motion; any length. resolution is WIDTH_HEIGHT (480_832 / 720_1280 portrait, 832_480 / 1280_720 landscape); 1080p is available afterwards via upscale_video. Credits are charged on create (see preview_cost) and refunded if the job fails. Returns the job id and initial status; generation takes 8-15 minutes, so call wait_for_job(model='craftstory-2') repeatedly until it reports done, then get_job_result for the video URL.

Start a minimax-h3 generation from one photo. mode='basic': user_prompt (scene description) + requested_duration_s (5-15); the model animates the photo and generates the soundtrack itself. mode='reference': the reference model. With audio_clip_id the clip is lip-synced to it (first 15 s billed) and user_prompt is optional. Without audio_clip_id, pass requested_duration_s and a user_prompt with the spoken line in quotes: the model voices it and generates the soundtrack. Either way up to 8 extra image / 3 video / 2 audio reference_files with reference_captions keep a second person, a product or a background consistent. Output is 768 px on the short side, orientation follows the photo. Cost 3.3 credits per billed second, charged on create. Returns the job id; call wait_for_job(model='minimax-h3') until done (1-3 min).

Status of a video job or audio clip: status, status_percentage, status_failed, credits_refunded. Terminal states: done; failed*, rejected_* and not_pass_moderation (audio) are failures. Prefer wait_for_job, which polls for you.

Full record of a job. For craftstory-2 the video is in video, for minimax-h3 in video_url, for audio clips in file; all are signed URLs valid for 7 days (call again for a fresh link). Also returns the parameters used and the credits charged.

Polls a job's status every few seconds for up to timeout_s (default 45, max 55 - most MCP clients cut a tool call at 60 s) and returns as soon as it is terminal. If it returns state='running', call it again - craftstory-2 jobs take 8-15 minutes, minimax-h3 1-3 minutes, audio clips seconds. Reports progress notifications when the client supports them.

Creates a NEW job with the upscaled result; the original stays. craftstory-2: only 720p sources, resolution 1080_1920 (from 720_1280) or 1920_1080 (from 1280_720). minimax-h3: always 2x, no resolution needed. Costs 0.2 credits per second. Poll the returned id with wait_for_job.
