## Python Usage

```python
import requests

api_key = "up_xxx"

# Sync
with open("doc.pdf", "rb") as f:
    response = requests.post(
        "https://api.upstage.ai/v1/document-digitization",
        headers={"Authorization": f"Bearer {api_key}"},
        files={"document": f},
        data={"model": "document-parse", "output_formats": "['markdown']"}
    )
print(response.json()["content"]["markdown"])

# Async for large docs
with open("large.pdf", "rb") as f:
    r = requests.post(
        "https://api.upstage.ai/v1/document-digitization/async",
        headers={"Authorization": f"Bearer {api_key}"},
        files={"document": f},
        data={"model": "document-parse"}
    )
request_id = r.json()["request_id"]

# Poll for results
import time
while True:
    status = requests.get(
        f"https://api.upstage.ai/v1/document-digitization/requests/{request_id}",
        headers={"Authorization": f"Bearer {api_key}"}
    ).json()
    if status["status"] == "completed":
        break
    time.sleep(5)
```

## LangChain Integration

```python
from langchain_upstage import UpstageDocumentParseLoader

loader = UpstageDocumentParseLoader(
    file_path="document.pdf",
    output_format="markdown",
    ocr="auto"
)
docs = loader.load()
```

---

## Environment Variable (Alternative)

You can also set the API key as an environment variable:

```bash
export UPSTAGE_API_KEY="your-api-key"
```

---

## Tips

- Use `mode=enhanced` for complex tables, charts, images
- Use `mode=auto` to let API decide per page
- Use async API for documents > 20 pages
- Use `ocr=force` for scanned PDFs or images
- `merge_multipage_tables=true` combines split tables (max 20 pages with enhanced mode)
- Results from async API available for 30 days
- Server-side timeout: 5 minutes per request (sync API)
- Standard documents process in ~3 seconds
