Subnet Burn History
Last updated
Fetch one subnet's registration-cost series. One subnet's registration-cost series (#9402) — how SubtensorModule.Burn has moved, captured every 15 minutes into D1 from the same single-call chain read /chain/burn uses. The live routes answer 'what does it cost'; this answers 'is it getting more expensive', which is the question an operator deciding where and WHEN to register actually has. ?window=24h|7d|30d|90d (default 7d), newest first, bounded. change_tao/change_pct describe the movement across the RETURNED window and are null when there is nothing to compare against — a single point has no change, and a change from a zero base has no percentage. A subnet with no recorded prices returns an empty series, never a 404.
Path Parameters
0 <= value <= 65535Query Parameters
Trailing lookback window the response is computed over, ending at the most recent data point rather than at today. Accepts 24h, 7d, 30d, 90d. A longer window is not a superset of a shorter one -- rankings and rates are recomputed over the whole window, not summed.

- "24h"
- "7d"
