## Input Schema

| Parameter | Type | Required | Default | Constraints | Description |
|-----------|------|----------|---------|-------------|-------------|
| prompt | string | Yes | - | - | Prompt for generated image |
| control_image | string | Yes | - | image/jpeg, image/png, image/jpg, image/webp | Image used to control the generation. The depth map will be automatically generated. |
| num_outputs | integer | No | 1 | 1–4 | Number of outputs to generate |
| num_inference_steps | integer | No | 28 | 1–50 | Number of denoising steps. Recommended range is 28-50, and lower number of steps produce lower quality outputs, faster. |
| guidance | number | No | 10 | 0–100 | Guidance for generated image |
| seed | integer | No | - | - | Random seed. Set for reproducible generation |
| output_format | string | No | webp | webp,jpg,png | An enumeration. |
| output_quality | integer | No | 80 | 0–100 | Quality when saving the output images, from 0 to 100. 100 is best quality, 0 is lowest quality. Not relevant for .png outputs |
| disable_safety_checker | boolean | No | false | - | Disable safety checker for generated images. |
| megapixels | string | No | 1 | 1,0.25 | An enumeration. |

## 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-depth-dev",
  "input": {
    "prompt": "A tropical beach",
    "control_image": "https://storage.googleapis.com/magicpoint/inputs/flux-depth-dev-input.webp"
  }
}'
```

## Output Schema

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

```json
{
  "status": "success",
  "predictionID": "string",
  "output": "string (URL of generated image)",
  "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-depth-dev — Image-to-Image AI Model**

flux-depth-dev, developed by Black Forest Labs as part of the flux-dev family, empowers developers to manipulate and analyze depth maps in images for precise image-to-image transformations. This model excels in generating depth-aware edits, enabling creative control over spatial structure in outputs like 3D scene reconstruction or layered compositions. Developers seeking an **image-to-image AI model** with depth estimation find flux-depth-dev ideal for applications requiring accurate depth manipulation without separate preprocessing tools.

Built on Black Forest Labs' advanced rectified flow transformer architecture, flux-depth-dev processes input images to produce depth-informed variations, supporting high-resolution outputs up to 1024x1024 and beyond. It addresses common challenges in **Black Forest Labs image-to-image** workflows by integrating depth analysis directly into the generation pipeline.

## 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.
