### Status Values

| Status | Description |

| `pending` | Job submitted, waiting in queue |
| `processing` | Job is being processed by a worker |
| `completed` | Job finished - check `data.outputs[0].url` |
| `failed` | Job failed - check `data.error.message` |
| `cancelled` | Job was cancelled |

### Python Polling Example

```python
import time, requests

job_id = submit_response.json()["data"]["jobId"]

while True:
    resp = requests.get(f"https://api.e2x.ai/v1/jobs/{job_id}",
        headers={"Authorization": "Bearer YOUR_API_KEY"})
    data = resp.json()["data"]

    if data["status"] == "completed":
        print("Done!", data["outputs"][0]["url"])
        break
    elif data["status"] == "failed":
        raise Exception(f"Job failed: {data['error']['message']}")

    time.sleep(2)
```

## Usage Notes

- All monetary values are in micro-cents (1,000,000 = $1 USD)
- For structured parameters such as `elements` or `shots`, send real JSON arrays/objects, not quoted strings.
- Use `webhookUrl` parameter in your submit request to receive completion callbacks instead of polling
