}List billed accounts
Returns each account that counted toward activeAccounts in the month, with the real fills that made it count and when the first and last of them happened — the reconciliation companion to /api/partner/usage. The list is computed from the same query as the count, so it always sums to the billed number — when your records disagree with an invoice, this is the level where the difference shows up.
Accounts are named by their venue account number — the identifier your firm issued when it created them. No trader identity fields appear on this surface.
Scope, month semantics, and refusals are exactly those of /api/partner/usage: your own firm only, resolved from the key; month is YYYY-MM UTC defaulting to the previous complete month; a malformed month is a 400; and a deployment without metering answers 404 rather than an empty list that would read as “no accounts billed”.

}Authorizations
A partner-scoped API key (trdrs_sk_…), issued to a trdrs Connect partner firm and accepted only under /api/partner/. Same format as the firm (tenant) key, different scope: a firm API key is refused here, and this key is refused everywhere else.
Query Parameters
The month to report, YYYY-MM. Defaults to the previous complete month.
^\d{4}-\d{2}$Response
The accounts that counted in the month (PartnerUsageAccountsResponse)
PartnerUsageAccountsResponse. The accounts behind the usage number — always sums to activeAccounts for the same month.
Your firm’s name, as trdrs holds it.
The month reported, YYYY-MM (UTC).
How accounts were attributed — same meaning as on /api/partner/usage. unattributable comes with an empty list.
rithmic-system, unattributable One entry per account that counted, ordered by account number.
