## Input Schema

| Parameter | Type | Required | Default | Constraints | Description |
|-----------|------|----------|---------|-------------|-------------|
| prompt | string | Yes | - | - | The prompt to edit the image. |
| image_urls | array | Yes | - | 1–4 | The URLs of the images for editing. A maximum of 4 images are allowed, if more are provided, only the first 4 will be used. |
| guidance_scale | number | No | 2.5 | 0–20 | Guidance Scale is a measure of how close you want the model to stick to your prompt when looking for a related image to show you. |
| image_size | string | No | square_hd | square_hd,square,portrait_4_3,portrait_16_9,landscape_4_3,landscape_16_9 | The size of the image to generate. The width and height must be between 512 and 2048 pixels. |
| num_images | integer | No | 1 | 1–4 | The number of images to generate. |
| enable_prompt_expansion | boolean | No | false | - | If set to true, the prompt will be expanded for better results. |
| enable_safety_checker | boolean | No | true | - | If set to true, the safety checker will be enabled. |
| output_format | string | No | png | jpeg,png,webp | The format of the generated image. |
| seed | integer | No | - | - | The seed to use for the generation. If not provided, a random seed will be used. |

## 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": "flux-2-turbo-edit",
  "input": {
    "prompt": "Change the time of day to night",
    "image_urls": [
      "https://storage.googleapis.com/magicpoint/inputs/flux-2-turbo-edit-input.png"
    ]
  }
}'
```

## Output Schema

Response returned by `GET /v1/prediction/{id}` when the job completes:

```json
{
  "status": "success",
  "predictionID": "string",
  "output": "array",
  "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

**flux-2-turbo-edit — Image Editing AI Model**

Developed by Black Forest Labs as part of the FLUX.2 family, flux-2-turbo-edit is a speed-optimized image-to-image editing model that transforms static images through natural-language instructions and precise color adjustments. Unlike traditional image editors that require manual pixel-level control, flux-2-turbo-edit interprets text prompts to intelligently modify compositions, lighting, objects, and styling while maintaining photorealistic quality. This image-to-image AI model solves the core problem of rapid visual iteration: designers, marketers, and developers can now edit images at production speed without sacrificing control or quality.

The model combines the turbo-speed optimization Black Forest Labs pioneered in their text-to-image pipeline with native editing capabilities, enabling users to make complex visual changes in seconds rather than minutes. Whether you're adjusting product photography for e-commerce, refining creative concepts, or automating batch image modifications, flux-2-turbo-edit delivers the responsiveness of a real-time tool with the precision of a professional editor.

## 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.
