}Read the accounts behind the venue's usage
Preview: served on the sandbox to every venue; production availability is arranged when a venue qualifies. Trading API keys and Partner keys do not authorize these routes. Requires a verified authorized operator session; writes require a trusted origin. venue:read. Runs the same operation the Legacy Partner API route runs, and refuses the same things; this is the venue twin of it, not a second implementation. One entry per account that counted, by account number, with the fills that made it count; always sums to activeAccounts for the same month.
