## Step 3: Send a Request

### Text generation example

```bash theme={null} theme={null}
curl -X POST https://api.elkapi.com/v1/chat/completions \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-5.5",
    "messages": [
      {
        "role": "user",
        "content": "Hello, please introduce yourself"
      }
    ]
  }'
```

### Image generation example

```bash theme={null} theme={null}
curl -X POST https://api.elkapi.com/v1/images/generations \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-image-1.5",
    "prompt": "A cute panda",
    "size": "1:1",
    "n": 1
  }'
```

### Video generation example

```bash theme={null} theme={null}
curl -X POST https://api.elkapi.com/v1/video/generations \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "veo-3.1-generate-preview",
    "prompt": "Waves crashing against the shore",
    "duration": 4,
    "size": "1280x720"
  }'
```

## Step 4: Check Task Status

Because we use asynchronous processing, you need to query task status to obtain results.

```bash theme={null} theme={null}
curl -X GET https://api.elkapi.com/v1/video/generations/YOUR_TASK_ID \
  -H "Authorization: Bearer YOUR_API_KEY"
```
