GET/api/v1/series/{series_id}

Get series

One series the way the series page shows it: metadata, then either a day index or a page of events.

Public. Returns 404 if the series is unknown. live_n is markets still trading, counted from close time rather than the number stored when each window was first seen.

Query parameters

Name	Notes
`day`	`YYYY-MM-DD` UTC. On a day-cadence series, returns that day's markets instead of the day index.
`status`	`live`, `closed`, or `settled`. Applied to markets and events, not to the day index.
`q`	Ticker or title tokens, on a day or an event list
`from_ts` / `to_ts`	Unix seconds. Days that miss the range are left out of the index.
`offset`	Page through days, or through markets once `day` is set
`event_offset`	Page through events on an event-cadence series
`limit`	Default 80, max 200

Cadence

cadence: day is a repeating window (15-minute crypto). The response has days, each { "day", "markets_n" }. Pass day to get markets.

cadence: event is a list of occasions. The response has events. A series with exactly one event includes redirect_event, which is the event id the app opens directly.
