## Input Schema

| Parameter | Type | Required | Default | Constraints | Description |
|-----------|------|----------|---------|-------------|-------------|
| prompt | string | Yes | - | - | The prompt for image editing. |
| image_urls | array | Yes | - | 1–10 | The URLs of the images to use for image-to-image generation or image editing. |
| aspect_ratio | string | No | 1:1 | 1:1,3:2,2:3,3:4,4:3,4:5,5:4,9:16,16:9,21:9 | The aspect ratio of the generated image. |
| output_format | string | No | png | jpeg,png,webp | The format of the generated image. |
| resolution | string | No | 1K | 1K,2K,4K | The resolution of the image to generate. |
| num_images | integer | No | 1 | 1–4 | The number of images to generate. |
| limit_generations | boolean | No | true | - | Experimental parameter to limit the number of generations from each round of prompting to 1. Set to `True` to to disregard any instructions in the prompt regarding the number of images to generate. |

## 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": "nano-banana-2-edit",
  "input": {
    "prompt": "Transform the uploaded scene into Synthetic Cubism style. Reconstruct the architecture using geometric planes, sharp angular shapes, fragmented perspective, and layered flat color blocks.",
    "image_urls": [
      "https://storage.googleapis.com/magicpoint/inputs/nano-banana-2-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

Nano Banana 2 | Edit, powered by Google as part of the Nano Banana family (Gemini 3.1 Flash Image), revolutionizes **image-to-image** transformations with Pro-level quality at lightning-fast Flash speeds. This model excels in advanced editing, enabling seamless refinements, precise control, and ultra-high-quality outputs guided by user prompts. Its primary differentiator is combining advanced world knowledge, subject consistency for up to five characters and 14 objects, and production-ready specs from 512px to 4K—all while delivering rapid iterations impossible with slower Pro models. Ideal for creators needing quick, accurate edits without sacrificing fidelity, Nano Banana 2 | Edit supports vibrant lighting, richer textures, and precise instruction following. Available via Google AI Studio, Gemini API, and each::labs, it powers efficient workflows for marketing mockups, storyboards, and more.

## 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.
