Authenticate with your MixRoute API Key using `Authorization: Bearer $MIXROUTE_API_KEY` and send JSON. The model ID belongs in the URL, not a body `model` field. Do not add `/v1` or wrap the request in `metadata`. ## Supported Models | Model | Generation Endpoints | Resolution | | --------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------ | | [Kling 3.0](/en/model-api/kuaishou/kling-3.0) | [Text to Video](/en/api-reference/endpoint/kling-text-to-video) / [Image to Video](/en/api-reference/endpoint/kling-image-to-video) / [Motion Control](/en/api-reference/endpoint/kling-motion-control) | Standard generation up to 4k; motion up to 1080p | | [Kling 3.0 Turbo](/en/model-api/kuaishou/kling-3.0-turbo) | [Text to Video](/en/api-reference/endpoint/kling-text-to-video) / [Image to Video](/en/api-reference/endpoint/kling-image-to-video) | 720p / 1080p | | [Kling 3.0 Omni](/en/model-api/kuaishou/kling-3.0-omni) | [Omni Generation and Editing](/en/api-reference/endpoint/kling-omni-video) | 720p / 1080p / 4k | | [Kling O1](/en/model-api/kuaishou/kling-o1) | [Omni Generation and Editing](/en/api-reference/endpoint/kling-omni-video) | 720p / 1080p | | [Kling 2.6](/en/model-api/kuaishou/kling-2.6) | [Text to Video](/en/api-reference/endpoint/kling-text-to-video) / [Image to Video](/en/api-reference/endpoint/kling-image-to-video) / [Motion Control](/en/api-reference/endpoint/kling-motion-control) | 720p / 1080p | | [Kling 2.5 Turbo](/en/model-api/kuaishou/kling-2.5-turbo) | [Text to Video](/en/api-reference/endpoint/kling-text-to-video) / [Image to Video](/en/api-reference/endpoint/kling-image-to-video) | 720p / 1080p | Use full identifiers available to your account. Endpoints and models must match: `kling-3.0-omni` and `kling-o1` use `omni-video`, not the standard text/image endpoints. Motion control uses `kling-3.0` or `kling-2.6`, not a separate motion model. ## Workflow 1. Select the endpoint and submit its native body. 2. Check both HTTP status and JSON `code`; `code=0` means the request succeeded. 3. Store submission `data.id` and query one gateway task ID at a time. 4. After `succeeded`, read `url` from `type=video` entries in `data[0].outputs`. 5. Never send your MixRoute Key to the result CDN. A submission timeout does not prove no task was created; do not retry POST automatically. ## Common Options | Field | Type | Required | Description | | -------------------------------- | ------- | -------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `options` | object | No | Common configuration object. | | `options.watermark_info.enabled` | boolean | No | Defaults to false. Set true to also provide a watermarked result. Custom watermarks are not supported. | | `options.external_task_id` | string | No | Custom business identifier, unique within the upstream account. Does not replace the gateway task ID or establish idempotency; MixRoute cannot query by it. | | `options.callback_url` | string | No | Callback URL forwarded upstream. Its IDs are upstream IDs, not the gateway data.id returned on submission. Do not identify the ID source by its prefix; poll to track the gateway task. | ## Defaults and Parameter Structure The gateway fills missing `settings.resolution` with `720p` and missing `settings.duration` with `5`, except for motion control. Text-to-video defaults to `16:9`. Image-to-video, Omni and motion control place prompts in a `contents` item of type `prompt`; only text-to-video uses root `prompt`. Explicitly set billing-sensitive fields, especially `1080p` for 2.6 native audio. Names and enum values are case-sensitive. Out-of-range values are not silently changed to another specification; each model still has its own constraints. Element and voice IDs must be accessible to the routed upstream account; assets in a personal Kling account are not automatically shared. ## Billing The following base rates are USD per generated second. Final charges depend on current [Model Marketplace](https://console.mixroute.ai/models) pricing, your account group multiplier and the console bill; resource-package or account-specific discounts are not included. | Model | Mode | 720p | 1080p | 4k | | ----------------- | ----------------------------- | ------------- | ----- | ------------- | | `kling-3.0` | Silent | 0.084 | 0.112 | 0.42 | | `kling-3.0` | Native audio | 0.126 | 0.168 | 0.42 | | `kling-3.0` | Motion control | 0.126 | 0.168 | Not supported | | `kling-3.0-turbo` | Native audio | 0.112 | 0.14 | Not supported | | `kling-3.0-omni` | No video input / silent | 0.084 | 0.112 | 0.42 | | `kling-3.0-omni` | No video input / native audio | 0.112 | 0.14 | 0.42 | | `kling-3.0-omni` | With video input | 0.126 | 0.168 | 0.42 | | `kling-o1` | No video input | 0.084 | 0.112 | Not supported | | `kling-o1` | With video input | 0.126 | 0.168 | Not supported | | `kling-2.6` | Silent | 0.042 | 0.07 | Not supported | | `kling-2.6` | Native audio | Not supported | 0.14 | Not supported | | `kling-2.6` | Native audio + voice | Not supported | 0.168 | Not supported | | `kling-2.6` | Motion control | 0.07 | 0.112 | Not supported | | `kling-2.5-turbo` | Silent | 0.042 | 0.07 | Not supported | Submission reserves quota; completion settles against actual fractional seconds in `outputs[].duration`, not only the requested integer duration. Motion control reserves 15 seconds and adjusts up or down to actual output duration. Failed or timed-out tasks release reserved quota. Optional native `billing` is upstream information, not proof of final MixRoute charges. Unsupported tiers are not free tiers.
