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; create_campaign runs the full pipeline; poll get_run until status is terminal, waiting poll_after_seconds between polls. Pass scheduled_at (ISO-8601) on create_campaign to queue a post when the render finishes. schedule_post queues a finished run. post_run queues a live…

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

  • render_asset changes data 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.

  • upload_product_screen changes data 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.

  • get_run reads 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). 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.

  • 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, 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.

    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.

  • list_styles reads auth-required 24h ago

    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).

Films play it when a brief names it ("launch film with our checkout demo"). Videos are for films; stills are painted from pictures.

  • get_account reads auth-required 6d ago

    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. Film renders need plan pro or above (empire/scale/pro).

  • clarify_brief reads auth-required never probed

    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.

  • 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.

  • studio_automate changes data auth-required never probed

    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.

_ 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.

_ for your README measured, not declared

measured by brick.blue

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

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ 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
0

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.
