Account Deregistrations
Last updated
Fetch one account's neuron-deregistration footprint per subnet over a recent window (7d/30d/90d): each subnet's NeuronDeregistered eviction count with the first and last eviction timestamps, plus account totals, an HHI concentration of where its deregistration activity is focused, and the dominant subnet — DERIVED from UID reuse (the slots where this account was the PREVIOUS holder); NeuronDeregistered has never been emitted by the runtime, the payload's derivation block states the lower bound, and degraded marks an answer nothing derived. The eviction-side complement to GET /api/v1/accounts/{ss58}/registrations and the account-level companion to GET /api/v1/chain/deregistrations, distinct from GET /api/v1/accounts/{ss58}/subnets (current registration state).
Path Parameters
An SS58-encoded account address -- a hotkey or coldkey.
Query Parameters
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.
"30d"Value in
- "7d"
- "30d"
- "90d"
