# Runway video API

Call Runway on Omniall AI in two styles:

| Style | Create | Poll |
| - | - | - |
| **Unified (recommended)** | `POST /v1/task/submit` | `GET /v1/task/{task_id}` |
| **Official** | `POST /runwayml/v1/image_to_video` · `POST /runwayml/v1/video_to_video` | `GET /runwayml/v1/tasks/{task_id}` |

Unified aliases: `POST|GET /runway/v1/task/...`.

**Host:** `https://api.omniall.ai` · Auth `Authorization: Bearer sk-...`.

Example models: `gen4_turbo`, `gen4_turbo/image-to-video`, `gen3a_turbo`, `gen4_aleph`, `gen4.5/image-to-video`. See the [Model Square](https://omniall.ai/pricing).

| Scenario (unified) | Key `input` fields |
| - | - |
| Text-to-video | `promptText` + optional `ratio` / `duration` |
| Image-to-video | `promptText` + `promptImage` |
| Video-to-video | `videoUri` + `promptText` |

```bash theme={null}
curl -X POST "https://api.omniall.ai/v1/task/submit" \
  -H "Authorization: Bearer $API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gen4_turbo",
    "input": {
      "promptText": "A paper plane flying over a quiet lake",
      "ratio": "16:9",
      "duration": 5
    }
  }'
```
