```

## 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 "Authorization: Bearer YOUR_API_KEY"
```

| Status | Meaning |
|--------|---------|

| `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.

## Overview

**kling-avatar-v2-standard — Image-to-Video AI Model**

Kling Avatar V2 Standard transforms static portrait images into expressive talking avatar videos synchronized with audio. This image-to-video model solves a critical problem for content creators, marketers, and developers: generating natural, character-driven video content without manual animation or expensive production workflows. By combining a single image with an audio track, kling-avatar-v2-standard produces videos where facial movements, lip-sync, and expressions automatically align with speech patterns—eliminating the need for frame-by-frame animation or green screen recording.

Developed by Kling as part of the kling-avatar family, kling-avatar-v2-standard delivers solid, reliable performance across diverse character types: photorealistic humans, stylized cartoon characters, illustrated figures, and even anthropomorphized animals. The model preserves the exact visual identity and style from your input image while animating facial features and subtle head movements, making it ideal for creators building an AI video generator for social media, e-learning, corporate communications, and character-driven storytelling.

## Usage Notes

- API Base URL: `https://api.eachlabs.ai/v1`
- Authentication: send `Authorization: Bearer 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.
