## Top Up Organization Prepaid Balance

`$ nirvana organizations:billing top-up`

**post** `/v1/organizations/{organization_id}/billing/topup`

Charge the card on file and credit the prepaid balance. A unique Idempotency-Key header is required; reuse it across retries so a timed-out top-up is not charged twice.

### Parameters

- `--organization-id: string`

  Path param: Organization ID

- `--amount: string`

  Body param: Amount to charge and credit, in USD. Must be greater than 0, at most two decimal places, and at most 10000.

- `--idempotency-key: string`

  Header param: Unique idempotency key scoping the charge; reuse the same value across retries so a timed-out top-up is not charged twice

### Returns

- `organization_billing_summary: object { daily_cost, effective_balance, monthly_cost, 3 more }`

  Forward-looking billing summary for an organization. All costs are run-rate projections from the organization's current active usage ("≈ $X/mo at current usage").

  - `daily_cost: string`

    Arbitrary-precision decimal serialized as a string (e.g. "58.40").

  - `effective_balance: string`

    Arbitrary-precision decimal serialized as a string (e.g. "58.40").

  - `monthly_cost: string`

    Arbitrary-precision decimal serialized as a string (e.g. "58.40").

  - `recharge_threshold_days: string`

    Arbitrary-precision decimal serialized as a string (e.g. "58.40").

  - `estimated_next_charge_at: optional string`

    Projected date the balance reaches the recharge threshold at the current run-rate. Null when there is no active usage (never charges).

  - `runway_months: optional string`

    Arbitrary-precision decimal serialized as a string (e.g. "58.40").
