## Authentication

```

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

## Quick Start

### Text-to-Video

```javascript
import wavespeed from 'wavespeed';

const output_url = (await wavespeed.run(
  "bytedance/seedance-v1.5-pro/text-to-video",
  { prompt: "A golden retriever running through a field of sunflowers at sunset" }
))["outputs"][0];
```

### Image-to-Video

The `image` parameter accepts an image URL. If you have a local file, upload it 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/seedance-v1.5-pro/image-to-video",
  {
    image: imageUrl,
    prompt: "The person slowly turns and smiles at the camera"
  }
))["outputs"][0];
```

You can also pass an existing image URL directly:

```javascript
const output_url = (await wavespeed.run(
  "bytedance/seedance-v1.5-pro/image-to-video",
  {
    image: "https://example.com/photo.jpg",
    prompt: "The person slowly turns and smiles at the camera"
  }
))["outputs"][0];
```
