Flexible position details, including the portion not yet accruing

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

GET /v1/earn/positions returns only total principal. This endpoint adds pending_principal, the portion that has not begun accruing interest.

It answers one of the most common support questions: “I deposited yesterday; why is there no return today?” Without it, you can only say the system is calculating.

It is calculated live from the step table, not a stored column. pending_value_at is the earliest pending accrual-start time; an empty string means all principal is accruing.

⚠ pending_principal is a subset already included in principal, not an additional amount.

⚠ Flexible redemption is LIFO, consuming non-accruing principal first. This number therefore also identifies the amount redeemable now without losing any accrued interest.

pending_interest is accrued but unpaid; paid_interest has already reached available balance.
