api record

Siren is the customer's deterministic marketing engine: one brief becomes on-brand images, videos, and posts. Call get_account first to learn the plan and scopes, then get_brand_dna and fix what its checks name (thin Brand DNA makes generic films). Browse films with list_films, then describe_film for a film's body contract. Films are 25 credits; platinum films (list_platinum_films, ids end in -plt) are 50 and only for a big launch the human wants to go far. create_campaign runs the full pipeline; poll get_run until status is terminal, waiting poll_after_seconds between polls. Pass…

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

list_platinum_films reads auth-required 32d ago
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.

boost_post auth-required never probed

Boost any post Siren made: it becomes a Meta ad with its own picture or video and caption, sent PAUSED. No credits; nothing spends until go_live_ad_campaign and the human's yes. Pass the run_id, or a post_id from list_posts (each row says boosted_campaign_id once it is). With neither it lists the posts that did best lately so you can pick one with the human.

create_campaign changes data auth-required never probed

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 film (list_films has the catalog); omit it and Siren picks. 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. FILM KNOBS: voiceover (true narrated / false music only), direction (mood, pace, motion, music in one line), music (a bed id), media (upload_media URLs the film shows). Images ignore the film knobs: Siren writes and paints them from the brief and Brand DNA. ANY BRAND: pass `brand` to make it for a brand that is not this workspace's own, e.g. brand={"name": "Acme", "site": "acme.com", "logo_url": "https://acme.com/logo.png", "primary": "#FF4400"}. Nothing of this workspace's identity leaks in. The exact same request within 24 hours returns the run it already started, as it is now, with replayed=true and no new charge. Change the brief to make another.

list_films reads auth-required 32d ago

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 another film on the shelf unless the human asked for that one). Page on with next_page. Want it all at once? all=true, or fetch the catalog file (https://api.mysiren.ai/api/v1/films.md, every film by shelf, also .txt/.json) and read it in steps. search= finds films by word. Then describe_film for the body. Videos are on every plan; credits are the only limit. Every film here is 25 credits. Platinum films (50 credits) are not in these pages: the answer's platinum section flags them, and list_platinum_films has the shelf.

list_styles auth-required 32d ago

The still style library, one ranked page at a time. Every painted still (an ad creative, poster, release 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).

upload_media changes data auth-required never probed

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).

edit_asset auth-required never probed
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.

post_run sends messages auth-required never probed

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 call queues the post behind a short publish window (about two minutes, cancellable) rather than firing inline: poll get_run after that and read `posts[].url` for the live permalink and the caption that went out.

upload_product_screen auth-required never probed

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.

studio_edit auth-required never probed

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 answer and no new version.

studio_design_pack auth-required never probed
The design tokens behind a Studio design, for building in the same language: palette, fonts, radius and shadow as `tokens`; `css` (custom properties plus a Tailwind v4 @theme block); `tailwind` (a v3 theme); and `skill_md`, a short rules file to drop into the project so the agent keeps to it. Call it once the version has been exported, so `screens` carries the rendered proofs and `exported` is true. Free and read-only: it reads a design, it does not render one. Honest about scope: palette, fonts, radius and shadow; no type scale or spacing ramp yet.

studio_export auth-required never probed
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 the run id: poll get_run until it is terminal, then show the human the file or post it with post_run.

arguments 25 lines
get_run auth-required never probed
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: when `ok` is false, show the human the video and the findings and let them decide. Re-render at most once, and only for a defect you can name in what you sent (a missing image, a wrong name). `notices` are plain-words notes on the request (e.g. it asked for a mood the brand's look does not wear): the asset is made as asked; pass the note to the human. A finished run carries `caption`: the post caption Siren wrote in the run's brand (or yours, if you passed one); show it with the asset. After post_run, `posts[]` carries each platform's status and, once it fires, the live URL and the caption that went out.

ads_overview auth-required 8d ago
The workspace's ads at a glance: spend today and this month against the caps, live campaigns, connected ad accounts, every campaign with its status and budget, and how many of Siren's suggestions are open. Call first for anything about ads. Ads need Pro and the owner's ads switch for this agent; a 403 `scope_ads` says where they turn it on.

ad_account_balance auth-required 8d ago
What each ad account has spent, its spending limit, what's left under it, and the platform's billing link. No app can add money to an ad account: to top up, give the human billing_url.

render_asset auth-required never probed
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?, caption?, voice_id?, music?, direction?, brand_override?}. Prefer create_campaign unless the user has concrete seed JSON. Returns run ids, `estimated_seconds` and `poll_after_seconds`; wait that long, then get_run. THE DIRECTOR: every film body is edited against Brand DNA before it renders. It keeps the film and your brand-specific lines, rewrites empty, generic or reference-body copy, and never touches media. `director` in the response says what changed. `direction` is a free line ("dark, club energy, fast") that steers words, pace and music. A film that cannot use what you sent returns 422 film_does_not_fit with a `fix` and `films_that_fit`. ANY BRAND: put brand_override={"name": "Acme", "site": "acme.com", "logo_url": "https://acme.com/logo.png", "primary": "#FF4400", "accent": "#111111"} on an item to render it for a brand that is not this workspace's own. With a name it is a clean slate: none of this workspace's logo, mascot, font, handle, screenshots or stills are used. Media slots take only URLs you uploaded with upload_media.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 284021b6e5e34039.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/284021b6e5e34039/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/284021b6e5e34039/badge.svg)](https://brick.blue/agent/284021b6e5e34039?ref=badge)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know

card completeness

100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
