Tech and industry (Energy and utilities), Spot price

Today's electricity price hour by hour as a departures board: the price for the hour that is now on flaps with its unit, under it the tariff, the day and what the price includes, a board of the cheapest and the peak hour with their prices and lamps, the day's prices as columns with the source, complete on the first frame, the supplier's notice at the foot throughout. The board ripples, then now, the cheapest and the peak are told in turn, before a tip, the button and the presenter. Eleven seconds.

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.

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.
