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. create_campaign runs the full pipeline; poll get_run until status is terminal. Pass scheduled_at (ISO-8601) on create_campaign to queue a post when the render finishes. schedule_post queues a finished run. post_run publishes now. Sequential platforms: X, LinkedIn, Instagram, TikTok, YouTube. Always confirm live posts with the user first. Credit or plan errors come back structured; relay them verbatim.

_ used through this hub 30 days

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.

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.

  • get_account auth-required 4h 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.

  • get_brand_dna auth-required 4h ago

  • create_campaign unknown 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). 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.

  • clarify_brief unknown never probed

  • render_asset unknown never probed

    Render pre-formed SirenSeed bodies directly (advanced): deterministic template render, no planner.

    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.

  • update_brand_dna unknown never probed

  • upload_product_screen unknown 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.

_ 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.

_ 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.
