## Input Schema

| Parameter | Type | Required | Default | Constraints | Description |
|-----------|------|----------|---------|-------------|-------------|
| video_url | string | Yes | - | - | URL of the input video. |
| image_url | string | Yes | - | - | URL of the input image. If the input image does not match the chosen aspect ratio, it is resized and center cropped. |
| resolution | string | No | 480p | 480p,580p,720p | Resolution of the generated video (480p, 580p, or 720p). |
| seed | integer | No | - | - | Random seed for reproducibility. If None, a random seed is chosen. |
| num_inference_steps | integer | No | 20 | 2–40 | Number of inference steps for sampling. Higher values give better quality but take longer. |
| enable_safety_checker | boolean | No | false | - | If set to true, input data will be checked for safety before processing. |
| shift | number | No | 5 | 1–10 | Shift value for the video. Must be between 1.0 and 10.0. |
| video_quality | string | No | high | low,medium,high,maximum | The quality of the output video. Higher quality means better visual quality but larger file size. |
| video_write_mode | string | No | balanced | fast,balanced,small | The write mode of the output video. Faster write mode means faster results but larger file size, balanced write mode is a good compromise between speed and quality, and small write mode is the slowest but produces the smallest file size. |

## 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": "wan-v2-2-14b-animate-replace",
  "input": {
    "video_url": "https://storage.googleapis.com/magicpoint/inputs/wan-v2-2-14b-animate-replace-input-video-url.mp4",
    "image_url": "https://storage.googleapis.com/magicpoint/inputs/wan-v2-2-14b-animate-replace-input-imagee.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 |

## 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.
