Historical validator dividends per subnet

Endpoint

GET /api/dtao/validator/dividends/history/v1

Description

Returns a historical time series of validator dividend snapshots. Each row splits alpha and root dividends between the validator’s own share (after take) and the nominator share, and reports the per-kt nominator return — letting you chart a validator’s yield or a nominator’s expected returns over time.

Use hotkey and netuid to isolate a validator on a subnet. Bound the window with block_number, block_start/block_end, or timestamp_start/timestamp_end, and downsample with frequency (e.g. daily vs. hourly buckets).

Parameters

Name	In	Type	Required	Description
hotkey	query	string		Filter by validator hotkey (SS58 or hex).
netuid	query	integer		Subnet id.
block_number	query	integer		Return the snapshot at this exact block.
block_start	query	integer		Start of block range (inclusive).
block_end	query	integer		End of block range (inclusive).
timestamp_start	query	integer		Start of Unix timestamp range in seconds (inclusive).
timestamp_end	query	integer		End of Unix timestamp range in seconds (inclusive).
frequency	query	—		Bucket size for the returned series, e.g. hourly, daily.
page	query	integer		1-based page number.
limit	query	integer		Page size (max 200).
order	query	—		Sort order, e.g. block_number_desc, day_desc.
