Historical hotkey emissions per subnet

Endpoint

GET /api/dtao/hotkey_emission/v1

Description

Returns per-block emission amounts credited to a hotkey on a given subnet. Each row splits the emission into the subnet-native emission (alpha) and the root_emission share flowing from the root network, letting you audit exactly what a validator or miner earned at each block.

Filter by hotkey and netuid to focus on a specific position, and use block_number, block_start/block_end, or timestamp_start/timestamp_end to bound the window. For background on the split see Emissions.

Parameters

Name	In	Type	Required	Description
hotkey	query	string		Filter by hotkey (SS58 or hex).
netuid	query	integer		Subnet id.
block_number	query	integer		Return the emission 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).
page	query	integer		1-based page number.
limit	query	integer		Page size (max 200).
order	query	—		Sort order, e.g. block_number_desc, emission_desc.
