## Overview

GPT-4o Image is called in two steps: create a generation task, then poll the task until the result is ready.

## Authentication

All requests require a Bearer Token in the request header:

```
Authorization: Bearer YOUR_API_KEY
```

## Create Task

`POST https://you.bot/api/v1/generate`

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| modelId | string | Yes | Model id: `gpt-4o-image` |
| input | object | Yes | Input parameters object (see below) |
| callbackUrl | string | No | https URL to receive a signed webhook on completion |

### input object parameters

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| imageUrl | string | No | Image URL |
| prompt | string | Yes | Text value (default: A watercolor map of a fictional seaside town, hand-lettered street names, tiny sailboats in the bay, pastel palette.) |
| size | string | Yes | Options: 3:2 | 2:3 | 1:1 (default: 3:2) |
| isEnhance | boolean | No | In most cases, enabling this is unnecessary. However, for specific scenarios like generating 3D images, enabling it can produce a more refined effect. Use discretion. (true/false) (default: false) |
