Retrieves per-cooldown-group assignment usage for all LSP (Liquidity Support Program) participant subaccounts configured under the authenticated main account.

Must be called with an API key belonging to the main account — returns an error if called from a subaccount. Use the user_id parameter to filter the result down to a single participant.

As with private/get_lsp_usage, each participant's group usage reports pct (limit, as a percentage of equity), used (USD within the current fixed window — flat until the window closes, then resets to 0 in one step), and cooldown_start/cooldown_end (the current window's timing) — remaining capacity is not computed for you and the leverage-derived cap applied at assignment time is not exposed on any user-facing endpoint.
