## Authentication

```bash

```

Get your API key at [wavespeed.ai/accesskey](https://wavespeed.ai/accesskey).

## Quick Start

### Text-to-Image

```javascript
import wavespeed from 'wavespeed';

const output_url = (await wavespeed.run(
  "bytedance/seedream-v4.5",
  { prompt: "A minimalist coffee shop logo with clean typography" }
))["outputs"][0];
```

### Image Editing

The `images` parameter accepts an array of image URLs (1-10 images). If you have local files, upload them first with `wavespeed.upload()` to get a URL.

```javascript
import wavespeed from 'wavespeed';

// Upload a local image to get a URL
const imageUrl = await wavespeed.upload("/path/to/photo.png");

const output_url = (await wavespeed.run(
  "bytedance/seedream-v4.5/edit",
  {
    images: [imageUrl],
    prompt: "Add warm sunset lighting and lens flare"
  }
))["outputs"][0];
```

You can also pass existing image URLs directly:

```javascript
const output_url = (await wavespeed.run(
  "bytedance/seedream-v4.5/edit",
  {
    images: ["https://example.com/photo.jpg"],
    prompt: "Add warm sunset lighting and lens flare"
  }
))["outputs"][0];
```
