Features

• ✅ Document conversion (PDF, DOCX, HTML, images, etc.)
• ✅ OCR processing with multiple engines
• ✅ Table extraction and structure analysis
• ✅ Image handling and processing
• ✅ Async/sync support
• ✅ Type-safe with Pydantic models
• ✅ Comprehensive error handling

Installation

# Clone or download the SDK
cd docling_serve_sdk

# Install with uv
uv pip install -e .

# Or with pip
pip install -e .

Quick Start

from docling_serve_sdk import DoclingClient

# Create client
client = DoclingClient(base_url="http://localhost:5001")

# Check health
health = client.health_check()
print(f"Status: {health.status}")

# Convert document
result = client.convert_file("document.pdf")
print(f"Content: {result.document['md_content']}")

Examples

Basic Conversion

from docling_serve_sdk import DoclingClient

client = DoclingClient(base_url="http://localhost:5001")
result = client.convert_file("document.pdf")

print(f"Status: {result.status}")
print(f"Processing time: {result.processing_time:.2f}s")
print(f"Content: {result.document['md_content']}")

Custom Options

from docling_serve_sdk import (
    DoclingClient, 
    ConvertDocumentsRequestOptions,
    InputFormat,
    OutputFormat,
    ImageRefMode,
    OCREngine
)

# Create custom options
options = ConvertDocumentsRequestOptions(
    from_formats=[InputFormat.PDF, InputFormat.DOCX],
    to_formats=[OutputFormat.MD, OutputFormat.HTML],
    image_export_mode=ImageRefMode.EMBEDDED,
    do_ocr=True,
    ocr_engine=OCREngine.EASYOCR,
    include_images=True,
    images_scale=2.0
)

# Convert with options
client = DoclingClient(base_url="http://localhost:5001")
result = client.convert_file("document.pdf", options=options)

Async Usage

import asyncio
from docling_serve_sdk import DoclingClient

async def convert_document():
    client = DoclingClient(base_url="http://localhost:5001")
    
    # Check health
    health = await client.health_check_async()
    print(f"Status: {health.status}")
    
    # Convert document
    result = await client.convert_file_async("document.pdf")
    print(f"Content: {result.document['md_content']}")

# Run async function
asyncio.run(convert_document())

Error Handling

from docling_serve_sdk import DoclingClient, DoclingError, DoclingAPIError

client = DoclingClient(base_url="http://localhost:5001")

try:
    result = client.convert_file("document.pdf")
    print(f"Success: {result.status}")
except DoclingError as e:
    print(f"Docling error: {e}")
except DoclingAPIError as e:
    print(f"API error: {e}")
    print(f"Status code: {e.status_code}")
except Exception as e:
    print(f"Unexpected error: {e}")
