      summary: Get current HIP-3 breadth above session VWAP
      description: Get the latest aggregate percentage of eligible HIP-3 instruments trading above their current UTC-session VWAP. Each instrument contributes one vote; VWAP uses candle quote volume divided by base volume and compares the last completed 1-minute candle close. The session resets at 00:00 UTC. Instruments with no session volume or a last completed candle older than 5 minutes are excluded, so coverage varies by market hours. `value_pct` is null when no instruments are eligible, never 0. This route is aggregate-only and does not expose per-symbol VWAPs. Snapshots are written every minute. Data collection begins August 28, 2026.

      summary: Get HIP-3 breadth above session VWAP history
      description: Get historical aggregate HIP-3 breadth snapshots. Each row reports the percentage of eligible instruments above their current UTC-session VWAP and its auditable counts. Eligibility excludes instruments with no session volume or a last completed candle older than 5 minutes, so coverage varies by market hours. `start` and `end` are Unix timestamps in milliseconds and default to the last 24 hours. The optional `interval` downsamples by selecting the last stored snapshot in each bucket; percentages are never averaged because the denominator can vary. The optional `cursor` is an epoch-millisecond timestamp from `meta.next_cursor` and is exclusive. Snapshots are written every minute. Data collection begins August 28, 2026.
