```

## 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 |
|--------|---------|
| `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.

## Overview

**kling-v1-pro-ai-avatar — Image-to-Video AI Model**

Kling AI Avatar Pro is a specialized image-to-video model designed to transform static images into expressive, animated videos with cinematic quality. Developed by Kling as part of the kling-v1 family, kling-v1-pro-ai-avatar solves a critical problem for creators: generating lifelike avatar animations and character videos without requiring complex motion capture or manual animation work. Whether you're producing talking head videos, character animations, or personalized avatar content, this model delivers high-fidelity results with advanced lipsync and motion control.

The core strength of kling-v1-pro-ai-avatar lies in its customizable lipsync technology paired with advanced realism and expressive motion. Unlike standard image-to-video models that apply generic motion to static images, this Pro variant prioritizes facial animation accuracy and character expressiveness—making it ideal for avatar-driven content where authenticity and emotional resonance matter.

## 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.
