Article

A story told as an article: the headline, the line under it, the byline and the picture on the cover, then the text in up to six paragraphs, a page at a time at a size that reads, the headline small over every page: 10 to 35 seconds. In eight styles, each wearing your brand's colours, fonts, logo, presenter and background.

Use cases

• Your news as people read it: an announcement, a launch, a market comment or a report.
• The headline and a picture on the cover, then the text a page at a time at a size that reads.
• Who wrote it and where it comes from, written exactly as you send them.

Variants

A variant is this template drawn another way, and it comes in versions: immutable builds, the newest first. A channel follows the newest version of its variant, unless it is pinned to one.

What it accepts

Every variant takes the same content, so one document draws in any of them.

Article: a headline, the line under it and a picture on the cover, then the text in up to six paragraphs, a page at a time at a size that reads, with who wrote it and the source. metaData is the post's title, descriptions and hashtags and is never drawn.

Field	Type	Required	Limit	What it is
clipData	group	yes		Clip data: Everything drawn: the headline, the line under it, the picture, the text, the byline, the source and the look.
clipData.kicker	text		up to 20 characters	Kicker: A word or two above the headline, such as NEWS or MARKET UPDATE.
clipData.title	text	yes	up to 90 characters	Headline: The story in one line. The cover's heading, and the line over every page after it.
clipData.lead	text		up to 160 characters	Line under the headline: What the story is about, in a sentence, on the cover.
clipData.picture	video		media:// picture or video from the media library, alt text up to 120 characters	Picture or video: The story's picture, on the cover with the headline. Left out, the headline and its line have the cover to themselves. A video from the media library plays in its place, without its sound, and from its start again whenever it ends.
clipData.pictureFit	enum		auto, fill, whole	Picture fit: Automatic, the default, fills the frame when a picture is close to its shape and shows it whole when filling would cut off more than a sixth of it, so no picture is cropped away. Fill the frame always crops to the frame, right for photographs; Show it whole never crops, right for logos and cut-out products.
clipData.pictureFocus	enum		centre, top, bottom, left, right	Picture focus: Which part of a picture stays in view when it fills its frame and its edges are cropped: the middle, or one side.
clipData.paragraphs	list	yes	at least 1, up to 6	Text: One to six paragraphs, as many to a page as fit at a size that reads. Each adds five seconds.
clipData.paragraphs[]	text		up to 300 characters	Paragraph
clipData.byline	text		up to 60 characters	Byline: Who wrote it and when, under the line on the cover, drawn as written.
clipData.source	text		up to 70 characters	Source: Where the story comes from, at the foot. Drawn exactly as written: write its label too, as the template adds no word of its own.
clipData.styleWords	group			Style words: The few words some styles write into their own frame, each drawn exactly as written, in the language you write it in. A word left out is not drawn: no template adds a word of its own. The same keys in every format of the collections; each style draws only its own.
clipData.styleWords.live	text		up to 16 characters	Live marker (Broadcast news): Written beside the light in Broadcast news' channel bug, such as LIVE. Left out, the light stands alone.
clipData.styleWords.byline	text		up to 12 characters	Byline (Editorial): Written before the presenter's name in Editorial, such as By. Left out, the name stands alone.
clipData.styleWords.functionKeys	list		up to 4	Function keys (Data terminal): Data terminal's row of keys F1 to F4, one word each, in order, such as HELP, DATA, CHART and NEWS; the second is drawn held down, and a key that does not fit the row is left out. Left out, no keys are drawn.
clipData.styleWords.functionKeys[]	text		up to 12 characters	Key
clipData.styleWords.commandKey	text		up to 10 characters	Command key (Data terminal): The key at the end of Data terminal's row, in the rise colour, such as GO. Left out, none is drawn.
clipData.styleWords.realTime	text		up to 12 characters	Real-time light (Data terminal): Written beside the blinking light in Data terminal's status bar, such as RT. Left out, the light stands alone.
clipData.styleWords.messageLabel	text		up to 12 characters	Message window label (Data terminal): The tab on Data terminal's message window round the presenter, such as MSG. Left out, the window has no tab.
clipData.styleWords.pictureLabel	text		up to 12 characters	Picture panel label (Data terminal): Written in the strip along the top of Data terminal's picture panels, such as IMG. Left out, the strip stays empty.
clipData.look	group			Look: How the clip looks and moves within its style. The same switches in every format of the collections. Leave a switch out, or set it to the style's own, and the style decides.
clipData.look.theme	enum		auto, brand, light, dark, bold	Theme: The style's own choice; your brand's own colours and background; a light or dark page tinted with your brand colour; or your brand colour as the page.
clipData.look.pace	enum		auto, calm, standard, punchy	Pace: How things arrive: the style's own rhythm, calm fades, a standard rhythm, or punchy slams and cuts.
clipData.look.corners	enum		auto, square, soft, round	Corners: The shape of cards, panels and marks.
clipData.look.align	enum		auto, start, centre	Text alignment: Where the text lines up.
clipData.look.logo	enum		auto, free	Logo: The style's own: the logo on the style's plate (a card, a disc, a badge) 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.
clipData.look.hideHeader	boolean			Hide logo and title: Leaves out the line at the top of the clip: your logo, the title line and the style's decoration around them, so the content starts at the top. To leave it out of every clip, switch Logo and title line off in your brand's settings.
clipData.look.hideFooter	boolean			Hide footer line: Leaves out your footer line at the foot of the clip, with whatever the style draws only to carry it, so the content reaches further down. Your presenter and the source line stay. To leave it out of every clip, switch Footer line off in your brand's settings.
clipData.look.pattern	enum		auto, none, dots, grid, lines	Background pattern: The fine texture behind the content. The style's own keeps what the style draws there, and some styles draw none. None leaves the background plain. Dots, Grid and Diagonal lines draw that pattern faintly instead, the same in every style, in the colour of your page.
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.
