Tiers are agreed with Nxos up front and defined on our side — this endpoint returns only the ones agreed with you, so a tier negotiated by another broker is never visible here. Assign one with `PUT /v1/organizations/sub-org-tier`. Requires the sub-organizations (broker) feature. Contact us to enable it. ## OpenAPI ````yaml GET /v1/sub-org-tiers openapi: 3.0.0 info: title: nxos API version: 1.0.0 contact: name: nxos url: https://nxos.io description: |- The nxos platform API provides programmatic access to accounts, balances, quotes, and trades.
