The add-on is sold per **calendar month (US Central time), paid in advance**: it is on during a month only when that month is paid. With auto-renew on, next month is charged 2 days before the current month ends (one retry the next day); an unpaid month switches the add-on off when it starts. ## OpenAPI ````yaml /api-reference/openapi.json get /v1/user/addons/market-depth 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.
