## JavaScript Example

```javascript
const API_KEY = 'YOUR_API_KEY';

// Submit job
const submitResponse = await fetch('https://pixeldojo.ai/api/v1/models/p-video-2-pro-replace/run', {
  method: 'POST',
  headers: {
    'Authorization': `Bearer ${API_KEY}`,
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    "video": "https://example.com/clip.mp4",
    "images": [
      "https://example.com/person.jpg"
    ],
    "resolution": "768p"
  })
});

const job = await submitResponse.json();

// Poll for completion
const pollForResult = async (jobId) => {
  while (true) {
    const statusResponse = await fetch(`https://pixeldojo.ai/api/v1/jobs/${jobId}`, {
      headers: { 'Authorization': `Bearer ${API_KEY}` }
    });
    const status = await statusResponse.json();
    
    if (status.status === 'completed') return status.output;
    if (status.status === 'failed') throw new Error(status.error);
    
    await new Promise(r => setTimeout(r, 2000));
  }
};

const output = await pollForResult(job.jobId);
console.log('Output:', output);
```

## Use Saved Characters (@Name)

Write `@Name` in the prompt to use a character, product, outfit, location, prop or style saved in the account's Character Studio, for example `"@Mara on a beach at sunset"`. Its photos are added to `images` automatically, after any images you send yourself, so your own image numbering is unchanged. List saved names with `GET /api/v1/characters` and save new ones with `POST /api/v1/characters`. An `@word` that names nothing saved stays plain text.
