## Example Request

```bash
curl -X POST https://api.eachlabs.ai/v1/prediction/ \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "model": "nano-banana-edit",
  "input": {
    "image_urls": [
      "https://cdn-us.eachlabs.ai/defaults/a4f61ab45ced6fad37ac83d0c7659a10b9422e2c6e2bbda05105995a4a8d74e6.png"
    ],
    "prompt": "Professional outdoor fashion photoshoot background. Modern city streets with elegant minimalist architecture, soft natural daylight, slightly overcast sky for diffused lighting. Neutral tones like beige, gray, and stone textures, creating a sophisticated and timeless atmosphere. Clean pavements, subtle depth of field, no distracting elements, high-end editorial style. "
  }
}'
```

## 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 "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

**nano-banana-edit — Image Editing AI Model**

Developed by Google as part of the **nano-banana** family, **nano-banana-edit** delivers fast inpainting for correcting errors or adding objects to existing images using simple text prompts, solving the need for time-consuming manual edits.

This **Google image-to-image** model, akin to Gemini 2.5 Flash Image capabilities, excels in mask-free inpainting and layout-aware outpainting, enabling precise changes like "replace the background with a snowy mountain" without altering unprompted areas.

Ideal for users seeking an **image-to-image AI model** with superior speed—generating edits in 1-5 seconds—**nano-banana-edit** maintains character consistency across modifications, making it perfect for iterative workflows in creative projects.

## 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.
