# 列出生成任务

`listGenerations`

`GET /v1/generations`

下面的接口说明为英文原文。

Lists the project's generations newest first (by created_at, then id). Pass next_cursor as cursor for the next page. Filters combine; created_after is inclusive and created_before exclusive.

## 鉴权

在请求头带上项目 API Key，例如 `Authorization: Bearer $VIZO_API_KEY`。API Key 只放在服务端。

### 200 OK

- `entries` (object[], 必填, 可为 null)
  - `allowed_actions` (string[], 必填, 可为 null)
  - `billing_closed_at` (date-time, 可选) When the hold was settled or released; absent while Credits are still held.
  - `billing_status` (string, 必填) Pending awaits funding; unfunded closed without a hold; held means Credits are held for the task; settled charges verified delivery at the existing pricing rules; released returns the hold after failure, cancellation, timeout or zero-charge delivery; refunded reverses previously consumed generation Credits. 可选值: `pending`, `unfunded`, `held`, `settled`, `released`, `refunded`
  - `closed_at` (date-time, 必填, 可为 null)
  - `created_at` (date-time, 必填) When the generation was accepted. Lists are ordered by this time, newest first.
  - `customer_resolution_deadline` (date-time, 必填)
  - `delivery_status` (string, 必填) Output delivery: pending before upstream success; copying into managed storage; ready after verified delivery; failed when delivery cannot complete. 可选值: `pending`, `copying`, `ready`, `failed`
  - `error` (object, 必填, 可为 null)
    - `code` (string, 必填) Funding: insufficient_balance, balance_negative (Credits were owed when the task came to be funded), budget_exceeded or spending_blocked; recovery_review when recovery closes an unfunded task for manual reconciliation. Provider: provider_unavailable after capacity/recovery exhaustion; input/output_moderated for safety refusal; input_media_invalid or input_media_unreachable for media refusal; draft_expired for an expired draft; input_rejected for unsupported input; delivery_failed when the provider succeeded but the output could not be stored; generation_failed for other terminal provider failures. Failed tasks release their customer hold. 可选值: `insufficient_balance`, `balance_negative`, `budget_exceeded`, `spending_blocked`, `recovery_review`, `provider_unavailable`, `input_moderated`, `output_moderated`, `input_media_invalid`, `input_media_unreachable`, `draft_expired`, `input_rejected`, `delivery_failed`, `generation_failed`

  - `held_at` (date-time, 可选) When Credits were held for the task; absent while it awaits funding or when it closed unfunded.
  - `id` (string, 必填)
  - `input` (any, 可选) The model input as accepted, after normalization, with media as sent: asset ids or your own URLs. Returned when reading a single task; list entries omit it.

  - `price` (object, 必填)
    - `charged` (string, 必填) Credits consumed by this task. Set when billing_status is settled: the actual usage the model reported at the fixed rate, which may be above or below estimated; any unused part of the hold returns to the balance, and usage above the hold is charged too. 0.000 in every other state, including after a refund.
    - `estimated` (string, 必填) The estimated cost of this task, in Credits, fixed when the task was accepted. This is the amount held for the task. The charge follows actual usage and may differ slightly from it, above or below.
    - `refunded` (string, 必填) Credits a refund returned to the balance: what this task had been charged. 0.000 unless billing_status is refunded.
    - `reserved` (string, 必填) Credits held for this task right now, as a decimal string with 3 places. Equal to estimated while billing_status is held, otherwise 0.000.

    - `voice_id` (string, 可选)
  - `run_ms` (integer, 可选) Milliseconds from first dispatch to close.

  - `started_at` (date-time, 可选) When the task was first dispatched to run.
  - `status` (string, 必填) processing from acceptance until the task closes, including while it awaits funding and while outputs are copied; succeeded has delivered outputs; failed, canceled and unresolved are closed. Canceled is set by the system only, for example when a task is not funded or not started in time. Unresolved closes after the resolution deadline. A late result may still arrive without a new charge. 可选值: `processing`, `succeeded`, `failed`, `canceled`, `unresolved`

所有错误使用同一种响应体。联系支持时请附上 request_id。

### 错误响应体

- `error` (object, 必填) 错误详情。
  - `code` (string, 必填) Stable request error code. invalid_input rejects the request schema; invalid_credentials/scope_denied reject authentication/authorization; ip_not_allowed/model_not_allowed reject API key IP/model restrictions; resource_not_found hides missing or inaccessible resources; conflict rejects incompatible state; insufficient_balance/budget_exceeded/spending_blocked reject funding; balance_negative (402) refuses new tasks while the organization owes Credits from a charge above its hold, until a top-up repays them; rate_limited/concurrency_limited ask for a later retry; temporarily_unavailable is transient service capacity; request_failed covers other HTTP failures. tier_not_sold, draft_not_found, draft_expired and input_duration_out_of_range reject model-specific input. input_media_invalid rejects a detected format/type mismatch; input_media_too_large rejects a probed byte size above the model limit. storage_quota_exceeded rejects an upload when the organization's storage is full. See errors for field-level details. 可选值: `invalid_input`, `invalid_credentials`, `insufficient_balance`, `balance_negative`, `scope_denied`, `resource_not_found`, `conflict`, `rate_limited`, `concurrency_limited`, `temporarily_unavailable`, `request_failed`, `ip_not_allowed`, `model_not_allowed`, `tier_not_sold`, `draft_not_found`, `draft_expired`, `input_duration_out_of_range`, `input_media_invalid`, `input_media_too_large`, `budget_exceeded`, `spending_blocked`, `storage_quota_exceeded`
