## 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": "pixverse-v6-transition",
  "input": {
    "prompt": "smooth transformation between scenes",
    "first_image_url": "https://cdn-us.eachlabs.ai/uploads/e711e49b-40f5-4e64-b023-5e4742a0670a.png",
    "last_image_url": "https://cdn-us.eachlabs.ai/uploads/7df8d025-bc1d-4523-a258-c4115a978614.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

**PixVerse | V6 | First-Last Frame Transition Overview**

PixVerse | V6 | First-Last Frame Transition from Pixverse specializes in generating smooth, cinematic videos that morph between a starting image and an optional ending image, creating fluid transitions up to 1080p resolution and 15 seconds long. This image-to-video model solves the challenge of bringing static imagery to life with professional motion, camera controls, and synchronized native audio, ideal for filmmakers, motion designers, and social media creators. Its primary differentiator is the seamless first-to-last frame capability, where users provide one or two images plus a text prompt to produce cohesive animations like seasonal changes or dynamic scene evolutions, complete with built-in styles such as anime or cyberpunk. Available via the **PixVerse | V6 | First-Last Frame Transition API** on platforms like each::labs, it streamlines workflows by integrating audio generation and multi-clip features for complete multimedia outputs without extra editing.

## 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.
