list_channelsList your channels. Every project lives in a channel, which owns the reusable styles (art/narrative/director) that drive generation.create_channelCreate a new channel — the container for projects and their reusable styles. Use when the user wants a fresh creative identity rather than adding to an existing channel.list_projectsList projects in a channel.create_projectCreate a project. The description (the video concept/topic) seeds script generation, so write a meaningful one. Pass video_format='portrait' for a vertical video — every shot, overlay, and the export are then composed for a 9:16 frame. The response's web_url is the project's pageget_projectFetch a project row — settings, voice config, default style, export URL.update_projectPatch project fields. Updatable: title, description, sfx_level, video_concept, voice_mix, voice_tts_provider, script_target_minutes, narrator_speed, video_format. (The narrator's TTS voice is NOT here — use set_narrator_voice.) narrator_speed is the narration rate (0.5-2.0, defaudelete_projectPermanently delete a project and everything in it (script versions, assets, voiceover, segments, renders). Irreversible — confirm with your user first.set_project_styleSet the project's default style — the style whose art/narrative/director fields drive its generations. Use after create_style to put a new visual identity into effect, or to switch a project between channel styles.update_caption_configMerge a patch into the project's burned-in caption config (keys like enabled, plus styling). Read the current value from get_project (caption_config). Applies at the next export — no rebuild needed.get_pipeline_progressTHE resume/orientation tool: one call returns every pipeline step's state (script -> scan -> reference_images -> voices -> voiceover -> style_templates -> storyboard -> segment_assets -> scenes -> export), any running jobs, and a next_action telling you exactly what to do next. Cget_workflow_statusPoll this between steps: returns active + recently-finished AI jobs (scope by project_id, or style_id for style analysis), plus per-segment- asset render statuses for projects. A step is done when its jobs reach status=complete (or error, with a user-readable message). NOTE: finiawait_jobsBlock (server-side) until the scope has no pending/running jobs, or the timeout passes — use this instead of polling get_workflow_status yourself. Returns {done, jobs}. If done=false the work is still running: just call await_jobs again (a 3-5 minute storyboard takes a few consecget_section_templateInspect the prompt sections a generation job exposes for per-call override via editable_sections (jobs: script, script_scan, storyboard, segment_image, segment_video, voice_block, ...). Sections marked locked cannot be overridden.list_modelsList the models allowed for a generation job, with display names, credit estimates, and each model's settings_schema — the valid keys for that tool's `settings` param (e.g. image quality/orientation, video duration). When model is omitted the server picks: the account's saved expgenerate_scriptGenerate the project's script from its description/concept and the channel's narrative style. Async — returns {job_id}; poll get_workflow_status.get_scriptRead the active script's full text + the version list. Use this to show the script to your user for review/feedback before scan_script — the review-edit-resave loop (get_script -> discuss -> save_script) is the expected workflow when the user wants input.save_scriptSave script text (your own draft, or an edited version of the generated one). Saving UPDATES the active version in place — the previous text is not kept, so show the user the current script (get_script) before overwriting it. New versions are created by generate_script runs, and revise_scriptAI-rewrite a passage of the active script in the project's narrative voice (the same in-editor revise the UI offers). selected_text must appear verbatim in the script; omit it to revise the whole script. `[SCENE: ...]` directions in range are preserved exactly, in place, unless tactivate_script_versionSwitch the project's active script to another saved version (ids come from get_script's version list — each generate_script run creates one; save_script edits the active version in place). Re-run scan_script / rescan_voice_blocks afterwards if the text differs, since downstream ascan_scriptAnalyze the active script: extracts character/environment/object assets and splits narration into voice blocks. DESTRUCTIVE on re-run (assets are recreated, not merged — curated descriptions, reference images, and voices are lost; prefer rescan_voice_blocks after script edits). Elist_assetsList the project's assets extracted by scan_script — characters, environments, objects. Each has a description (the spec every shot uses to render it — surfaced top-level here; the raw row nests it at ai_output.description), an optional reference image (file_path is a public URL create_assetManually add a character/environment/object the scan missed. asset_type: "character" | "environment" | "object". The description is the generation-facing spec of its look — be specific. The scan reads narration and `[SCENE: ...]` directions, so the common miss is anyone NEITHER eupdate_assetRename an asset and/or rewrite its description. If the look changed, regenerate its reference image afterwards so renders match.delete_assetDelete a project asset (e.g. one the scan over-extracted).generate_asset_referenceRender an asset's reference image in the channel's art style — the visual anchor that keeps a character/environment looking identical across every shot. EVERY character, environment, and object asset needs one before generate_voiceover (the server enforces this; fire the jobs forset_character_voiceBind a TTS voice to a character asset — required before generate_voiceover for every character with dialogue (the narrator's voice is separate: set_narrator_voice). Browse ids with list_voices.list_voicesList available TTS voices (id, label, preview audio URL) for a provider: "minimax" (default engine) or "elevenlabs". Match the project's voice_tts_provider (see get_project) so picked ids work with its engine. Returns {groups: {name: count}, voices}; the ElevenLabs catalogue is 1set_narrator_voiceSet the project's narrator TTS voice — required before generate_voiceover whenever the script has narration. Browse ids with list_voices. (Character dialogue voices are separate: set_character_voice.)list_voice_blocksList the project's voice blocks (per-speaker narration chunks) with their audio status and assigned voices. A block's `scene_direction` is the script's `[SCENE: ...]` direction governing it (never spoken; null when the span carries none). Word-level subtitle timings are stripped update_voice_blockOverride one voice block's voice or playback volume (block ids from list_voice_blocks). Re-run generate_voiceover for the block afterwards if you changed its voice — existing audio is not regenerated automatically.rescan_voice_blocksRe-extract voice blocks from the active script WITHOUT touching assets or their reference images — the non-destructive alternative to scan_script after a script edit. Blocks whose spoken text is unchanged keep their audio; only edited blocks come back empty, so a follow-up generagenerate_voiceoverGenerate TTS audio for the project's voice blocks. Without voice_block_ids it fills gaps: only blocks with no audio yet run, so re-calling it is always safe (already-generated and currently-generating blocks are skipped, never re-billed). Pass voice_block_ids to explicitly REgenegenerate_storyboardPlan the full visual storyboard: segments, shot pacing, image/video prompts, overlays, continuation chains — driven by the channel's director and art styles. Requires voiceover to exist (timing comes from it). Plans generated stills + real media only (real media requires the stylget_segmentsList the storyboard's segments (narration span, type, duration, creative direction). The 1-based segment_number is the handle every segment tool takes (update/split/combine/continuation/regenerate) — you never need a UUID. Returns {total, offset, returned, segments}; on big projeget_segment_assetsList one segment's assets (images/video/overlays) including their status, config (prompts, model), and public URLs of rendered files — pass an image's public_url to view_image to actually look at it.regenerate_segment_assetRegenerate a segment's primary image or video with optional overrides — the API equivalent of the editor's expert drawer. asset_type: "image" | "video" (for a video segment, "image" targets its start frame). Use a different model, override prompt sections (see get_section_templatrollback_segment_assetRestore a previously rendered version of a segment's image or video — every regeneration archives the render it replaces (last 5), so a regen that came out worse is reversible for free. The current render is archived in its place, making the rollback itself reversible. The frame/change_segment_typeChange what a segment's base visual IS: a generated still ("image"), fetched real media (media_source="real" — a real photo for "image", stock b-roll footage for "video"), or an overlay scene. Generated video is NOT set here — it's the state a rendered still reaches through animaanimate_segmentAnimate one segment in a single call: flip it to a generated video shot (keeping its rendered image as the clip's first frame) and START the clip render immediately. BILLS video credits on this call — the segment's image must already be rendered (400 otherwise). A refused generatupdate_segment_contentRewrite one segment's creative direction from feedback ("make this shot a close-up", "show the machine from above") — an LLM rewrites the shot's prompts; continuation links, SFX, and overlays are preserved. The visual assets reset to not_started: re-render them afterwards (generaRecent checks
