WHAT IT DOES

What get_chain_fees does on metagraphed — Bittensor subnet operational registry

AI agents call get_chain_fees to retrieve information from metagraphed — Bittensor subnet operational registry without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameter	Type	Required	Description
`limit`	integer	—	Maximum rows to return (1-100). Defaults to 25 when omitted. The response reports the limit actually applied.
`window`	string	—	Trailing time window to aggregate over, ending at the latest data point rather than a calendar boundary. Options are per-tool: `7d`, `30d`. Defaults to 7d.
`context`	string	—	Optional: the user's goal, briefly. Analytics only; does not affect the result.
`call_module`	string	—	Restrict to one pallet, by its runtime name (`SubtensorModule`). Case-sensitive.

Parameters from the server's own tool schema.
