GET/api/v1/markets/{ticker}/coverage

Get market coverage

How much of one market's trading time was recorded, and which of its days are published. The market page shows this as its coverage meter.

Needs an API key from your code (a free account has one). The Try button on this page works without one. Returns 404 if the ticker is unknown. It does not count toward the download allowance.

Fields

Field	Notes
`measured` / `pct`	Whether recorder health covers this market's time, and the % of it recorded. `pct` is `null` when not measured, and `detail` says why.
`start` / `end`	The stretch scored, in Unix seconds: from the open (or October 12, 2026, when recording began) to the close, or to now while the market is `open`.
`truncated`	True when the market ran longer than two weeks and only the latest two are scored.
`segments` / `lost_s`	Stretches with `status` `ok` or `loss`, and the seconds lost in all.
`days` / `published_days`	Each UTC day of that stretch with `published`, and how many are published.
`detail`	One sentence for people, for example "Recorded the whole time from open to close."
