Subnet Owner Capture

Last updated

GET
/api/v1/subnets/{netuid}/owner-capture

Measure how much of one subnet's emission reaches its owner, per day over a 7d/30d/90d window. Two chain-visible layers: the protocol owner cut (L1, 18%, the same for every subnet) and emission landing on UIDs held by the declared owner_coldkey (L2, which varies enormously -- the network median is far above 18%). Also lists those UIDs, each validator's take, and the measured fraction of stake behind them that is NOT the owner's. THIS IS NOT what the owner takes: the identity of those nominators (L3) and any treasury cut inside the subnet's own code (L4) are not observable here, and the response says so in blind_spots. Every other stakeholder address is reported unresolved, which is the honest default and not a finding against them.

Path Parameters

netuid*integer
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"
