Installation

pip install draggit-sdk

Quick Start

from draggit import DraggitClient

# Initialize client
client = DraggitClient(api_key="your-api-key")

# Sign PDF
result = client.sign_and_save(
    input_pdf="document.pdf",
    output_pdf="document_signed.pdf"
)

print(f"Signed! Used {result['signatures_used']} signatures")

Usage

Basic Signing

client = DraggitClient(api_key="demo-key")

# Sign and save
result = client.sign_and_save("input.pdf", "output.pdf")
# Returns: {
#   'status': 'success',
#   'message': 'PDF signed successfully with Draggit watermarks',
#   'tier': 'free',
#   'signatures_used': 1,
#   'output_file': 'output.pdf',
#   'file_size': 28136
# }

Check License

# Validate API key
is_valid, info = client.validate_license()

if is_valid:
    print(f"Valid! Remaining: {info['signatures_remaining']}")
else:
    print("Invalid or expired API key")

# Get detailed info
license_info = client.get_license_info()
print(f"Tier: {license_info['license_type']}")
print(f"Used: {license_info['signatures_used']}/{license_info['signatures_limit']}")

Configuration

from draggit import WatermarkConfig

# Get current config
config = client.get_config()

# Modify config
config.logo_x = 100
config.logo_y = 150
config.logo_opacity = 0.9

# Save config
client.update_config(config)

# Use presets
config = WatermarkConfig.preset_subtle()
config = WatermarkConfig.preset_default()
config = WatermarkConfig.preset_prominent()

API Keys

• demo-key - Free tier (100 signatures)
• pro-key - Pro tier (1,000 signatures)
• Contact support for custom keys

Configuration Options

Error Handling

from draggit import DraggitClient

try:
    client = DraggitClient(api_key="invalid-key")
except ConnectionError as e:
    print(f"Connection error: {e}")

try:
    result = client.sign_and_save("nonexistent.pdf", "output.pdf")
except FileNotFoundError as e:
    print(f"File error: {e}")
except ValueError as e:
    print(f"API error: {e}")
