## Rights

<Warning>
  Market data carries the tightest licensing in the API. Several feeds permit internal
  use but not redistribution, and those rows are served with metadata and a null value
  rather than silently omitted.

  Check `attribution` on any market row before putting it in front of an end user. See
  [Sources and rights](/concepts/sources-and-rights).
</Warning>

This is a property of the feed, not of your plan. No tier unlocks a value we do not
hold the right to pass on.

## Freshness

Market series are daily and follow exchange calendars. A gap over a holiday is the
calendar. A `freshnessStatus` of `stale` on a market series means the feed itself is
behind, which is worth alerting on.
