Months follow CME's clock (America/Chicago). The response stays small and fast regardless of how many cycles have accumulated. Months are keyed `YYYY-MM` (UTC, by cycle start date) and sorted ascending. A month with no cycles is simply absent. Use this for spend-over-time charts and month-over-month comparisons; use `GET /billing/summary?month=` for one month's line items. ## OpenAPI ````yaml /api-reference/openapi.json get /v1/organization/billing/monthly openapi: 3.0.0 info: title: Hyperprop Platform API version: 1.0.0 description: >- REST API for the Hyperprop Trading Platform — provision evaluation and funded trading accounts, manage traders and plans, react to account lifecycle events via signed webhooks, and reconcile billing.
