What it accepts
A product's tech specs as a keynote shows them: the product alone on the brand's ground, its name huge, complete on the first frame. Then the datasheet row by row, each figure counting to what was sent with its unit and condition, in pages, how the figures were measured under them. Then the end card. The footnote stays throughout. 1.2 seconds more per spec. metaData is never drawn.
| Field | Type | Required | Limit | What it is |
|---|---|---|---|---|
clipData | group | yes | Clip data: Everything drawn in the clip: the eyebrow, the product's name and line, its picture, the specs with their figures, units and conditions, how the figures were measured, the call to action and the footnote. | |
clipData.eyebrow | text | up to 24 characters | Eyebrow: A word or two above the name in the brand colour, such as Tech specs. | |
clipData.product | text | yes | up to 40 characters | Product name: The product's name, set huge on the cover, over the sheet and again on the end card. |
clipData.tagline | text | up to 90 characters | Line under the name: What the product is, in a few words, under its name on the cover. | |
clipData.picture | image | yes | media:// file from the media library, alt text up to 120 characters | Product picture: The product, from the media library. A cut-out (a PNG with a transparent background) stands whole on the ground with a soft shadow under it; a photograph fills a rounded frame. It stays on screen beside or above the sheet from the first frame to the last. |
clipData.specs | list | yes | at least 3, up to 12 | Specs: Three to twelve rows of the datasheet, in the order you want them read: what it is, the figure with its unit, and its condition under it. As many as fit stand on a page and the rest turn to the next page; the type is never made smaller to fit more. Each adds 1.2 seconds. |
clipData.specs[] | group | Spec | ||
clipData.specs[].label | text | yes | up to 28 characters | What it is: The spec's name, such as Battery life, Weight or Bluetooth. |
clipData.specs[].value | number | 3 decimals | Figure: The figure itself, such as 40 for 40 hours. It counts up to exactly what is sent, in the channel's language. Leave it out to set words in its place below. | |
clipData.specs[].valueText | text | up to 14 characters | Figure in words: Set as written in place of a figure, such as USB-C, Adaptive or 4 to 40,000, where the spec is not one number. | |
clipData.specs[].unit | text | up to 10 characters | Unit: Set small after the figure, such as hours, g, mm or Hz. | |
clipData.specs[].condition | text | up to 110 characters | Its condition: Shown small under the name: the condition this figure was measured in or what it covers, such as Up to, with noise cancelling on. A battery, range, charging or speed figure always needs one. | |
clipData.condition | text | yes | up to 160 characters | How the figures were measured: Shown under the sheet on every page: who measured the figures, when, on what and how, so no figure stands without its test. Never cut: a long one takes more lines. |
clipData.cta | group | Call to action: The button at the end and the line under it, such as a web address, a handle or a phone number. | ||
clipData.cta.label | text | yes | up to 28 characters | Button: What the button says. |
clipData.cta.detail | text | up to 48 characters | Line under it: An address, a handle, an app, a phone number. | |
clipData.footnote | text | up to 400 characters | Footnote: Shown small above your footer line on every frame: that results vary, that a screen is simulated, whose trademarks are named. A long one is set smaller, never cut. | |
clipData.look | group | Look: How the clip looks and moves. The same six switches in every format (theme, pace, corners, alignment, logo, logo size). Leave any out for the package's default: the brand's colours, calm, softly rounded, centred. | ||
clipData.look.theme | enum | brand, light, dark, bold | Theme: Brand: your brand's own colours and background. Light or dark: a page tinted with your brand colour. Bold: your brand colour as the page. | |
clipData.look.pace | enum | calm, standard, punchy | Pace: How things arrive: calm fades, a standard rhythm, or punchy slams and hard cuts. | |
clipData.look.corners | enum | square, soft, round | Corners: The shape of cards, pictures and buttons. | |
clipData.look.align | enum | start, centre | Text alignment: Where the text lines up. | |
clipData.look.logo | enum | auto, free | Logo: The style's own: the logo on a small plate so it reads on any page. As it is: the logo whole, with no plate, frame or crop, for a logo made to stand on the page, such as one with a transparent background. As it is, make sure your logo reads on the page of the theme you choose. | |
clipData.look.logoSize | enum | auto, small, large | Logo size: Standard is the style's own size. Small draws the logo a fifth smaller, with its plate. Large draws it a quarter larger wherever the style has room for it, and at the standard size where it has none. | |
metaData | group | Meta data: Everything about the post that is never drawn in the clip: its title, its description in four lengths, one per kind of platform, and its hashtags. Reelwire adds the brand's description, link and hashtags after it. Left out, the post text is generated from the clip data. | ||
metaData.title | text | up to 100 characters | Title: Used where the platform has a title of its own: Facebook Feed, LinkedIn, Pinterest and YouTube. Up to 100 characters, which every one of them takes. | |
metaData.captionTiny | text | up to 200 characters | Tiny description (Pinterest, Threads, X): Up to 200 characters. The brand's description, link and hashtags follow it within the platform's limit. | |
metaData.captionShort | text | up to 500 characters | Short description (Telegram, Threema, WeChat, WhatsApp): Up to 500 characters. The brand's description, link and hashtags follow it within the platform's limit. | |
metaData.captionMedium | text | up to 1500 characters | Medium description (Discord, Facebook Reels, Instagram, LinkedIn, Signal, Slack, TikTok): Up to 1500 characters. The brand's description, link and hashtags follow it within the platform's limit. | |
metaData.captionLong | text | up to 4000 characters | Long description (Facebook Feed, YouTube): Up to 4000 characters. The brand's description, link and hashtags follow it within the platform's limit. | |
metaData.hashtags | list | up to 15 | Hashtags: Written without the #. Up to 15, which every platform takes. | |
metaData.hashtags[] | text | up to 60 characters | Hashtag |
locales carries other languages: under each language code, the parts of clipData and metaData that differ, laid over the default, so a language with no copy still renders.
A picture is always a file from your media library: media:// followed by its id or its name.
Anything the table does not list is refused, and so is anything over its limit, with a 400
schema_validation error that names the field.

Delivery JSON
Your own system sends this to one of your streams, POST /v1/stream, and every channel listening to
that stream draws it with its template. data is the document described above; a stream with an
empty field map passes it to the template unchanged. Try it first on POST /v1/stream/validate,
which answers the same without publishing anything. Streams and feeds
explains the rest, including how to map a document of your own shape instead.

The delivery names no version: which build draws it is the channel's choice, the newest of its
variant or the one it is pinned to. eventId is a ULID you make once per event: sending the same
one again changes nothing. occurredAt is when the thing happened, not when you sent it. locale
is the language of the text in data, and data.locales carries other languages beside it.
