Lists an org's budget leases.

**Not available yet.** Sylphx Billing is declared in the registry but no backend serves it: every call answers `501` with the problem code `UNIMPLEMENTED`.

- **Path** `GET https://api.sylphx.com/v1/orgs/acme/budget_leases`
- **Scope** `billing:read`
- **Effect** `read` — nothing is written.
- **Collection** [budget_leases](/docs/api/budget_leases)
- **Query** `page_size`, `page_token`, `filter`, `order_by`
- **Pagination** the answer carries `budget_leases` and, when there is more, `next_page_token`

## Request

| Field | Type | What it is |
| --- | --- | --- |
| `parent` | `string` | The org to list in. Required. |
| `page_size` | `int32` | At most this many; default 50, clamped to 1000. |
| `page_token` | `string` | `next_page_token` of the previous page. |
| `filter` | `string` | AIP-160 filter over labels and filterable fields. |
| `order_by` | `string` | AIP-132 ordering over filterable fields. |

## Response

| Field | Type | What it is |
| --- | --- | --- |
| `budget_leases` | `BudgetLease[]` | The page. |
| `next_page_token` | `string` | The token of the next page; empty on the last page. |

### BudgetLease

| Field | Type | What it is |
| --- | --- | --- |

| `granted_nano_usd` | `int64` | Billing's valuation of the grant at list price, in nano-USD; 0 for a class Sylphx runs but does not sell. Output only. |
| `fence` | `int64` | The fence: monotonic per org, holder, and lease key; a renewal carrying an older value is refused. Output only. |
| `expire_time` | `timestamp` | When the holder stops debiting the lease. Output only. |

| `settled_debit_nano_usd` | `int64` | The debit rated from ingested usage, in nano-USD. Output only. |

| `create_time` | `timestamp` | When the Resource was created. Output only. |
| `update_time` | `timestamp` | When the Resource last changed. Output only. |
