  • get_account Get the connected Siren workspace: plan, key scopes, auto-post setting, and daily limit. Call this first to learn what the account can do before generating. Empty asset_types / channels / connected_accounts lists mean UNRESTRICTED, not missing — never stop on them. Films render on every plan; credit
  • list_runs List the workspace's generation runs (newest first): status, brief, channel, asset URLs, and caption. Page with offset to see them all.
  • get_run Get one run by id — full status, output text, asset URLs, caption, and any error. Poll this after create_campaign or render_asset until status is terminal. Wait `poll_after_seconds` between polls; `progress` and `eta_seconds` say how far along it is. A finished film carries `film_check`, advice only
  • create_campaign Create a Siren campaign from a plain-language brief — the full pipeline: plan, on-brand copy, deterministic render, verify. Returns the run; poll get_run until it finishes. Spends credits (image 10, an ad set of 3 images 20, video 25; voice or music-only is the same 25). Pass output_type to pin a fi
  • list_films The film library, one ranked page at a time. Films sit on job shelves; pass job and the human's goal and hire from the top of the page. Each film says what it is, when to hire it, its length and shapes, fits_this_brand (with what is missing) and made_recently (this brand already got it: prefer anoth
  • list_platinum_films The platinum shelf: studio-grade films that match a top motion studio's craft, told as the brand's own story. Each costs 50 credits, every time (a normal film is 25). Offer one only when the human is making a big launch they genuinely want to go far; everyday posts and normal budgets use list_films.
  • list_styles The still style library, one ranked page at a time. Every painted still (an ad creative, poster, launch card, App Store frame, thumbnail) is one style; Siren picks one when you don't. Styles sit on section shelves; pass section and the human's goal and take one from the top. made_recently = this bra
  • describe_film The full contract for one film: what it is and when to hire it, its body JSON Schema, a reference body, the seed envelope, media slots (which fields take image/video URLs), the brand prefills (colours, logo, screens) and the override rules. Call it before writing a render_asset body.
  • clarify_brief Ask Siren's clarifier whether a brief is specific enough to generate from. Returns ready=true/false plus follow-up questions. Use before create_campaign when the user's request is vague.
  • render_asset Render films from pre-formed SirenSeed bodies (advanced). FILMS ONLY: images are painted from a brief, so for any image, ad or creative call create_campaign with asset_type=card (a still here returns 422 stills_use_a_brief). Each item: {output_type, channel, seed_body, archetype?, family?, surface?,
  • upload_media Store a photo or video the human wants in a post, from an https URL or base64. Returns a workspace-owned URL to put in any media slot of a film body (describe_film lists the slots) — the renderer reads it directly. Images: PNG/JPG/WebP up to 15 MB. Videos: MP4/MOV/WebM up to 200 MB. The same bytes a
  • edit_asset Edit a finished ad creative in place. Only what the instruction names changes; faces, layout, lettering and every other pixel are kept, so you can chain edits (hair pink, then tail teal, then add a sign) without the picture drifting. About 15 seconds. 3 credits; an instruction that asks for a whole
  • post_run Post a finished run's assets to the workspace's CONNECTED SOCIAL ACCOUNT. This is live, public distribution on the customer's channel — always confirm with the user before calling. Only works if the grant was authorised with posting allowed. Pass `caption` to own the words; it goes out verbatim. The
  • schedule_post Schedule a finished run to post at scheduled_at (ISO-8601). Shows in the customer's local timezone. platforms: x, instagram, tiktok, linkedin, youtube, or everything. Posts fire sequentially. Requires Allow posting. Prefer this over post_run when the user names a time. On create_campaign you can pas
  • get_brand_dna Get this workspace's Brand DNA: brand_name, brand_kind, overview, tagline, offer, features, products, audience, palette, logos, plus `checks`: what to fix before rendering (thin Brand DNA, a typed accent the brand's own work does not use). Call right after get_account; fix thin DNA first with update
  • update_brand_dna Patch Brand DNA. Send only keys to change. Nested bags (offer, product_map, icp) merge. Examples: {tagline, overview, offer: {product_name, one_liner, features, who_its_for, primary_cta}, product_map: {offerings, how_we_work}, icp: {who_buys, pains}}. Does not read or write Brand Memory.
  • list_product_screens List the brand assets in Brand DNA: product photos, app screenshots, packaging. Each row has name, kind, description, use_when, tags, scan_status (scanning / ready / failed), device, theme, url.
  • upload_product_screen Upload a brand asset (product photo, app screenshot, packaging) into Brand DNA and store it on R2. Pass image_url (https PNG/JPG/WebP) or image_base64. Two ways to file it: - Send `description` (and optionally kind, use_when, tags, name): Siren trusts your words and files the asset as-is. No read
  • update_product_screen Edit an existing brand asset: name, description, kind, use_when, and the screenshot tags (screen_type, device, theme).
  • delete_product_screen Remove a product screenshot from Brand DNA. Does not delete Brand Memory.
  • upload_logo Set the workspace logo in Brand DNA. Every render uses it.
  • get_mascot The workspace mascot: status (hero, keeping, frames, ready), the hero picture, tries left, and every pose frame with its URL. Null mascot = none yet.
  • create_mascot Start the brand mascot: from a description (note, kind) or from a reference picture. Paid plans; 100 credits. Siren paints a hero in about a minute; poll get_mascot, show the human, then mascot_step keep (build the pose sheet) or retry (paint again, 3 tries). One mascot per workspace.
  • mascot_step Move the mascot on: keep the hero, paint it again, or add a pose. Ask the human before keep, since it builds the whole sheet.
  • list_people The people library: team faces Siren can put in stills (name, role, team, status cropping or ready, round crop URL).
  • add_person Add a face to the people library. Siren crops it round in a few seconds (status cropping, then ready). Only upload people who agreed.
  • delete_person Remove a face from the people library.
  • list_media Photos and videos uploaded with upload_media, newest first, with their URLs. Reuse a URL in create_campaign media or a film body.
  • get_performance How the posts did: totals (impressions, engagement, replies, engagement rate) and the top posts with views, likes and replies.
  • list_posts Every post Siren sent or queued: platform, status, live URL, time, and counts by status (posted, queued, failed).
  • buy_credits Get a Stripe checkout link for more credits. Give the link to the human; they pay on Stripe and the credits land in about a minute. Nothing is charged by this call. Read the balance on get_account.
  • list_brand_videos The brand's own clips in Brand DNA: name, what each shows, when to use it, tags, best moments with timestamps, poster and scan_status.
  • upload_brand_video Add a product demo, walkthrough or footage to Brand DNA. With only the file, Gemini reads frames across the clip and writes what it shows, when to use it, tags and the best moments (scan_status scanning, then ready in about 15 seconds; poll list_brand_videos). Films play it when a brief names it ("l
  • delete_brand_video Remove a clip from Brand DNA, file and poster included.
  • delete_media Delete one photo or video uploaded with upload_media. Only this workspace's uploads; a film that already rendered keeps its copy.
  • studio_templates List Siren Studio's 33 React data-card types with family, description, and body schema. Use this before studio_card so the body matches.
  • studio_card Render a Studio data card from a type + body. Deterministic React, no paint. Optional live post after render. Returns run_id, image url, and post url when posted.
  • studio_automate Create a Studio profile on this API key. Returns generate curl and inbound hook URLs (Stripe, GitHub, Uptime Kuma, Product Hunt, generic). Passing delivery.social_account_ids turns on social delivery for the profile — that publishes, so it requires Allow posting.
  • studio_schedule Render a Studio card then queue a ScheduledPost at scheduled_at.
  • studio_start Start a video in Siren Studio from a description. Siren composes the first take (about 10 to 20 seconds) and replies with what it made; nothing is rendered or charged until studio_export. Returns the thread and Siren's reply. The human sees the same thread in Studio and can keep editing it there, or
  • studio_edit Change a Studio video by asking, as the human would in the chat. Only what the ask names changes; Siren replies with what it changed (before and after) and the new version number. Waits up to about 25 seconds for the reply. No credits are spent until studio_export. A greeting or a question gets an a
  • studio_get One Studio video: the chat so far (who said what, with diffs), every version, and which version is current.
  • studio_threads The workspace's Studio videos, newest first: title, shelf, current version, and whether a human or an agent started it.
  • studio_export Render a Studio design or video to files. Spends credits like any render: a video 25 (platinum 50), a card 10, a set 10 a slide (an App Store set of 6 is 60), charged once. A card or a set waits for the render (about a minute) and returns every file in `asset_urls`, slide 1 first; a video returns th
