  -H "Content-Type: application/json" \
  -d '{
  "model": "kling-v1-standard-ai-avatar",
  "input": {
    "audio_url": "https://storage.googleapis.com/magicpoint/inputs/kling-video-v1-standart-ai-avatar-input.mp3",
    "image_url": "https://storage.googleapis.com/magicpoint/inputs/kling-video-v1-standart-ai-avatar-input.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 "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.

## Errors

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

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

## Overview

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

Kling AI Avatar Standard is an image-to-video model that transforms static images into expressive, lifelike avatar videos featuring people, animals, cartoons, and creative styles. Developed by Kuaishou Technology as part of the kling-v1 family, this model solves a critical problem for content creators: generating talking head videos and character animations without expensive studio setups or manual frame-by-frame animation. The model combines first-frame conditioning with smooth motion synthesis, allowing creators to input a single image and voice track to produce coherent, character-driven video content.

What distinguishes kling-v1-standard-ai-avatar from generic video generators is its specialized focus on avatar consistency and expressive motion. Rather than treating character animation as a secondary feature, this model prioritizes frame-to-frame appearance consistency and natural lip-sync performance, making it ideal for creators building talking avatar applications and character-driven narratives.

## 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.
