- add_personshallow
Add a face to the people library. Siren crops it round in a few seconds (status cropping, then ready). Only upload people who agreed.
- buy_creditsshallow
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.
- clarify_briefshallow
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.
- create_campaignshallow
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, video 25; voice or music-only is the same 25). Optional scheduled_at (ISO-8601) queues a sequential post (X → Instagram → TikTok, or platforms you pass) when the render succeeds — requires Allow posting. Fails with a 402 upgrade message if the plan or balance can't cover it.
- create_mascotshallow
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.
- delete_brand_videoshallow
Remove a clip from Brand DNA, file and poster included.
- delete_mediashallow
Delete one photo or video uploaded with upload_media. Only this workspace's uploads; a film that already rendered keeps its copy.
- delete_personshallow
Remove a face from the people library.
- delete_product_screenshallow
Remove a product screenshot from Brand DNA. Does not delete Brand Memory.
- describe_filmshallow
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.
- edit_assetshallow
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 new look ("make it a comic", "make it cinematic") repaints at 10. Returns the NEW run: poll get_run until it is terminal and show the human the new image. Films are not edited this way: re-render them with render_asset. Every earlier version stays, so the human can go back to any of them.
- get_accountshallow
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.
- get_brand_dnashallow
Get this workspace's Brand DNA: name, overview, tagline, offer, features, products, audience, palette, logos. Not Brand Memory.
- get_mascotshallow
The workspace mascot: status (hero, keeping, frames, ready), the hero picture, tries left, and every pose frame with its URL. Null mascot = none yet.
- get_performanceshallow
How the posts did: totals (impressions, engagement, replies, engagement rate) and the top posts with views, likes and replies.
- get_runshallow
Get one run by id — full status, output text, asset URLs, impact and audience scores, and any error. Poll this after create_campaign or render_asset until status is terminal.
- list_brand_videosshallow
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.
- list_filmsshallow
Every live film master Siren can render: name, what it is, when to hire it, runtime, aspect, whether this plan can render it, and `fits_this_brand` with what is `missing` for this workspace (films that fit come first). Films are deterministic MP4s; video renders need Pro or above. Read this before promising a specific film, then describe_film for its body.
- list_mediashallow
Photos and videos uploaded with upload_media, newest first, with their URLs. Reuse a URL in create_campaign media or a film body.
- list_peopleshallow
The people library: team faces Siren can put in stills (name, role, team, status cropping or ready, round crop URL).
- list_platinum_filmsshallow
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. Say the price before you render. Ids end in -plt. Platinum needs a paid plan or a credit top-up: a complimentary plan sees it but gets 402 platinum_needs_paid_plan. voice MM = motion and music only (no voice-over question, no narration); MVM = motion, voice and music. Then describe_film for the body, same as any film.
- list_postsshallow
Every post Siren sent or queued: platform, status, live URL, time, and counts by status (posted, queued, failed).
- list_product_screensshallow
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.
- list_runsshallow
List the workspace's recent generation runs (newest first): status, brief, channel, asset URLs, and audience scores.
- list_stylesshallow
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 brand already got that look, prefer another. To paint in a style, put its id in the create_campaign brief (asset_type card). The whole library as one file: https://api.mysiren.ai/api/v1/styles.md (also .txt/.json).
- mascot_stepshallow
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.
- post_runshallow
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.
- render_assetshallow
Render pre-formed SirenSeed bodies directly (advanced): deterministic template render, no planner. Each item: {output_type, channel, seed_body, archetype?, family?, surface?, caption?, voice_id?}. Prefer create_campaign unless the user has concrete seed JSON. Returns run ids — poll get_run for status.
- schedule_postshallow
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 pass scheduled_at instead.
- studio_automateshallow
Create a Studio profile on this API key. Returns generate curl and inbound hook URLs (Stripe, GitHub, Uptime Kuma, Product Hunt, generic).
- studio_cardshallow
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_scheduleshallow
Render a Studio card then queue a ScheduledPost at scheduled_at.
- studio_templatesshallow
List Siren Studio's 33 React data-card types with family, description, and body schema. Use this before studio_card so the body matches.
- update_brand_dnashallow
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.
- update_product_screenshallow
Edit an existing brand asset: name, description, kind, use_when, and the screenshot tags (screen_type, device, theme).
- upload_brand_videoshallow
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 ("launch film with our checkout demo"). Videos are for films; stills are painted from pictures.
- upload_logoshallow
Set the workspace logo in Brand DNA. Every render uses it.
- upload_mediashallow
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 are stored once (content-hashed).
- upload_product_screenshallow
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. - Send only the file: Gemini reads the picture and writes name, kind, description, use_when, tags itself. scan_status goes scanning → ready in about 8 seconds; poll list_product_screens. kind is free text ("product photo", "dashboard screenshot", "packaging"), there is no fixed list. A brief that names an asset ("advertise the pink handbag") pulls that file into the still. screen_type / device / theme only matter for device-framed screenshot masters.
