Platform stats
Public platform aggregates: all-time totals from the nightly analytics mart, the most recent measured day, and right-now market counts. Unauthenticated and identical for every caller. Every block carries its own as_of and basis; absent measurements serialize as null with an empty_reason rather than as zero.
Response
Always ‘measured’ — this surface never serves simulated figures.
The API’s own environment (‘production’, ‘staging’, …). Clients label anything that is not exactly ‘production’ as non-production data.
When this payload was composed (ISO-8601).
Right-now counts, read off the market card projection.
Platform totals over the mart’s retained window.
Deliberately NOT called all-time: the nightly job prunes the mart to its
retention horizon, so these sums cover window_start_dt onward and would
silently become a rolling window if they claimed lifetime coverage.
Every measurement is optional on purpose: when the mart has never built, or
holds no row, these serialize null with empty_reason set. A 0
here would be a measurement, and there isn’t one.
