## Input Schema

| Parameter | Type | Required | Default | Constraints | Description |
|-----------|------|----------|---------|-------------|-------------|
| prompt | string | No | - | - | Text prompt for video generation. Either prompt or multi_prompt must be provided, but not both. |
| image_url | string | Yes | - | - | URL of the start frame image. |
| end_image_url | string | No | - | - | URL of the end frame image (optional). |
| duration | string | No | - | 3,4,5,6,7,8,9,10,11,12,13,14,15 | Video duration in seconds (3-15s). |
| generate_audio | boolean | No | false | - | Whether to generate native audio for the video. |
| multi_prompt | array | No | - | 0–5 | List of prompts for multi-shot video generation. If provided, divides the video into multiple shots. |
| shot_type | string | No | customize | customize | The type of multi-shot video generation. |

## Example Request

```bash
curl -X POST https://api.eachlabs.ai/v1/prediction/ \
  -H "X-API-Key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "model": "kling-o3-pro-image-to-video",
  "input": {
    "image_url": "https://storage.googleapis.com/magicpoint/inputs/kling-o3-pro-image-to-video-input-image.png"
  }
}'
```

## Output Schema

Response returned by `GET /v1/prediction/{id}` when the job completes:

```json
{
  "status": "success",
  "predictionID": "string",
  "output": "string (URL of generated video)",
  "metrics": {
    "predict_time": "number (seconds)"
  }
}
```

## Polling

```bash
curl https://api.eachlabs.ai/v1/prediction/{PREDICTION_ID} \
  -H "X-API-Key: YOUR_API_KEY"
```

| Status | Meaning |
|--------|---------|
| `processing` | Still running — poll again |
| `success` | Done — read `output` |
| `error` | Failed — read `message` / `details` |

## Webhook (alternative to polling)

Pass `"webhook_url": "https://your.host/path"` in the create request. Eachlabs POSTs this payload when the job ends:

```json
{
  "exec_id": "prediction-uuid",
  "status": "succeeded",
  "output": "https://...",
  "error": ""
}
```

`status` is `"succeeded"` or `"failed"`. `exec_id` equals the `predictionID` from create. Return 2xx within 30 seconds.

## Errors

Error body: `{ "status": "error", "message": "...", "details": "..." }`

| Code | Meaning |
|------|---------|
| `400` | Invalid input |
| `401` | Missing / invalid `X-API-Key` |
| `404` | Unknown model or prediction id |
| `429` | Rate limit — 100 creates / min, 10 concurrent per key |
| `5xx` | Retry with backoff |

## Overview

**kling-o3-pro-image-to-video — Image-to-Video AI Model**

kling-o3-pro-image-to-video, developed by Kling as part of the unified kling-o3 family, is an image-to-video AI model that animates static images into smooth, physics-aware video sequences guided by text-based instructions. Rather than generating video from scratch, this model excels at bringing existing images to life—transforming a single frame or reference image into dynamic video with precise control over motion, style, and scene composition. For creators, marketers, and developers building AI-powered video tools, kling-o3-pro-image-to-video solves the challenge of converting static assets into cinematic content without manual keyframing or post-production stitching.

Built on the Omni One architecture that powers the broader kling-o3 ecosystem, this model combines 3D Spacetime Joint Attention with Chain-of-Thought reasoning to ensure motion feels natural and physically grounded. The result is an image-to-video generator that maintains subject consistency while adding dynamic camera work, lighting shifts, and environmental changes—all from a single text prompt and reference image.

## Usage Notes

- API Base URL: `https://api.eachlabs.ai/v1`
- Authentication: send `X-API-Key: YOUR_API_KEY`. Generate a key from the Eachlabs dashboard at https://www.eachlabs.ai/dashboard/api-keys.
- File-typed parameters (`*_url`, `image_url`, `video_url`, `audio_url`, etc.) accept publicly-reachable HTTPS URLs only. Upload your asset first (GCS / S3 / your CDN) and pass the resulting URL. Data-URIs and localhost URLs are rejected.
- For structured parameters (arrays / objects) send real JSON values, not stringified payloads.
- Monetary values are reported in USD; per-token / per-megapixel rates may be billed in micro-cents internally.
- Prefer `webhook_url` over polling for long-running predictions — see the Webhook Callback section.
