Fixed-term order details

GET /v1/earn/orders/{id} scope: earn:read
On behalf of a member · x-on-behalf-of required

The GET /v1/earn/orders list contains only status and maturity_date, insufficient for an order-detail page.

⚠ The rate is snapshotted into the order at subscription, so only this endpoint can provide its annualized rate, estimated interest, and principal plus interest at maturity. The product’s apr_bps is what a new order gets now, not this order’s rate.

expected_interest equals the actual maturity interest; we recalculate and assert equality at settlement. It can be displayed directly as the amount receivable at maturity.

⚠ rollover_mode values are none / principal / principal_interest, not both. Unknown subscription values silently fall back to the product default: a UI may show principal-and-interest renewal while another option executes, without any warning.

⚠ renewable is the product-level master switch and must be read with rollover_mode. When disabled, this order does not renew even if its row specifies renewal.
