Subnet Event Summary

Last updated

GET
/api/v1/subnets/{netuid}/event-summary

Fetch a windowed event summary for one subnet: account_events counts by kind and coarse category, distinct hotkey/coldkey counts, TAO/alpha sums where applicable, first/last evidence bounds, plus a newest-first evidence slice. ?window=7d|30d|90d (default 30d); ?limit caps recent_events (default 10, max 50). Computed live from the account_events store.

Path Parameters

netuid*integer

The subnet's numeric id on the Bittensor network, as used by the chain itself.

Range0 <= value

Query Parameters

window?string

Trailing lookback window the response is computed over, ending at the most recent data point rather than at today. Accepts 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.

Default"30d"

Value in

  • "7d"
  • "30d"
  • "90d"
limit?integer

Maximum number of rows to return in one page (at most 50). A larger value, or a non-positive one, is rejected with 400 invalid_query -- so a short page means the result set is exhausted, not that the server quietly capped you (#9916). Omitted, the server applies 10.

Range1 <= value <= 50
Default10
