Python Usage

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

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:

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
