Restore one saved editor action at the expected current revision. Requires the action ID from edit history and an idempotency key. Existing project data is changed.

Read existing suggested moments with source ranges, hooks, transcript excerpts and thumbnails before producing videos. Results are bounded; this does not generate suggestions or render clips.

Read bounded editable caption words and stable word IDs for one project, optionally matching text.

Replace selected caption words by their stable IDs. Preserves timing and the other captions; this does not change the spoken audio.

Save the user's 1-5 rating and optional quality category/comment against one completed playable video export. Replaces that user's previous feedback for this export; does not change accepted clips or defaults. Requires the feedback storage migration to be installed.

Restore editable project captions from the selected source's completed canonical transcript. Keeps the full recording and avoids duplicate captions on identical retries. Requires source transcription first; no-speech is an explicit successful state.

Recover a terminal batch's missing clip count through the persisted recovery workflow. Preserves accepted clips and returns the recovery batch ID. Can spend existing account credits; retry with the identical idempotency key.

List bounded workspaces the connected user belongs to, with their role and default workspace. Selecting a workspace for the task does not change account defaults.

Save the user-reviewed business name, audience, offer, conversion goal, tone, protected vocabulary and editorial preferences for the selected workspace.

List or inspect clips, regenerate, repair visual QA, start export, promote an accepted delivery export, inspect caption words, or apply a verified caption look.

Preview or delete a terminal clip batch. Dry-run is the default; real deletion requires explicit confirmation, retention choice, workspace delete permission, and an idempotency key.

List bounded managed clips from the selected source or project with their current workflow state.

Read one managed clip's selected source range, project, workflow state and delivery information.

Replace the source moment for one managed clip using a verified suggestion or explicit time range. Can spend existing account credits. Preserves the other clips; read current state before retrying.

Request a layout repair for one managed clip, such as preserving a screen demo or moving captions away from faces. Changes that clip's project; preserves the other clips.

Create or update up to 20 visual blocks in one call after edit timing is settled. Presets: broll-headline, steps, quote, end-screen, key-number, before-after, screenshot-focus, chapter. IDs are scoped to the project; repeating an ID updates it. Asset IDs must belong to the workspace. Atomic, undoable; dryRun validates without writing. Returns IDs and revision. No generation pass.

Check a queued generation. Completed jobs carry the media asset ID and a download URL.

Request cancellation of the identified queued or running generation. Work already performed can consume credits; cancellation does not establish a refund.

Read a generation brief from rawPrompt. Source-video edits return execution for generation_video_create with required assets and transformation controls. New scenes return an authoring grammar and planJsonSchema for generation_plan_validate. This read does not generate media or spend credits.

Validate a self-authored generation plan against the schema and the target model's real capabilities before execution. Returns directive errors to fix and revalidate; only a valid plan is executable.

Create a vertical video storyboard for the user-approved script in an existing project. Spends planning credits; returns scene narration, factual review notes, references and the production credit estimate. Does not generate images or animate video. Existing account access applies.

Read one authorized storyboard revision, its scene and reference previews, estimate, approvals and bounded polling guidance. Refreshes signed previews. Complete means the editable timeline is assembled; use exports_start and exports_list for a downloadable MP4.

Create a new immutable draft from a known revision with selected scene, character or model changes. Preserves other scene definitions; requires review and production approval again. Does not generate media or overwrite an approved revision.

After showing the storyboard and its credit estimate, confirmApproved=true starts production of reference images and scene keyframes. Spends existing credits. This stage produces reviewable previews, not animated videos.

After the user approves the generated previews and animation cost, confirmApproved=true starts scene animation, narration and editable timeline assembly. Can replace the project's generated timeline and spend existing credits. Follow the revision and then export the finished project.

Replace the identified preview after user approval of the new credit cost. A scene_keyframe changes one keyframe; a character_anchor refreshes its dependent keyframes; a style_anchor refreshes every keyframe. Preserves unaffected previews. Does not regenerate an already finished video shot.

Create or replace a Growth+ Series identity and defaults. defaultCreationMode selects podcast branding or faceless Story Kit defaults; membership stays mixed. Updates require expectedRevision. Existing content keeps its settings.

Assign, move or detach one source or project using expectedSeriesId. Moving a source does not move existing clips or change branding.

Delete the Series container at an expected revision and detach its content. Sources, projects and exports are preserved.

Create or replace a carousel project from a slide document. Server owns chip layout, safezones, and exact export pixels.

Render JPEG stills for a compiled carousel at the exact platform frame and return them as MCP images so you can inspect chips on the real slides.

Read the carousel slot document and the named template catalog.

Patch named slots or template_id on one slide. Re-rasters that slide only. Never rewrite HTML.

Reorder, remove, insert, duplicate, or undo slides on a compiled carousel. One write for the filmstrip. Insert rasters an empty named template unless sourceIndex copies a slide.

Turn a named recipe or a brief into compile-ready named-template slides. Expand never publishes and never invents metrics.

Rebuild a compile slot document from a legacy overlay carousel. Then patch slots like any compiled deck.

Duplicate a carousel onto a new project. Copies slots. Icon and shot values may be pack filenames or asset:<media_asset_id>.

Save or apply a theme, brand theme, or named slide template. Themes rewrite fonts, colors, overlay, and asset:<id> logos. Never persist signed URLs.

Schedule a completed project export to Instagram. Optional includeAffiliateCta appends Try BlitzReels for free plus the Affonso tracking URL. Requires an active Instagram account connected in the BlitzReels UI.

Schedule a selected existing video asset to explicit active YouTube, Instagram, Facebook, TikTok, LinkedIn or Threads accounts connected in the BlitzReels UI, using reviewed copy, privacy/consent choices, synthetic-media disclosure, time and timezone. Requires confirmPublish=true. Existing workspace permissions and provider access rules apply. A scheduled receipt is not proof of publication.

Read the current targets for one publishing receipt with scheduled/published state and verified remote URLs. Does not retry or publish a failed target.
