🔍 Code Extractor

Asynchronous function that tests authentication and API connectivity with the reMarkable Cloud service, verifying credentials and basic API access.

Purpose

This function serves as a diagnostic tool to validate reMarkable Cloud authentication credentials and confirm API accessibility. It creates a session, attempts to authenticate, and performs a test API call to retrieve root synchronization data. The function provides console feedback with emoji indicators for success/failure states, making it useful for debugging authentication issues or verifying setup before running main application logic.

Source Code

async def test_remarkable_auth():
    """Test reMarkable Cloud authentication"""
    print("🔐 Testing reMarkable Cloud authentication...")
    
    try:
        session = create_remarkable_session()
        print("✅ reMarkable authentication successful")
        
        # Test basic API call
        response = session.get("https://eu.tectonic.remarkable.com/sync/v4/root")
        if response.status_code == 200:
            print("✅ reMarkable API access confirmed")
            root_data = response.json()
            print(f"📊 Root hash: {root_data.get('hash', 'N/A')[:16]}...")
        else:
            print(f"⚠️ reMarkable API call failed: HTTP {response.status_code}")
        
        return True
        
    except Exception as e:
        print(f"❌ reMarkable authentication failed: {e}")
        return False

Return Value

Returns a boolean value: True if authentication and API access are successful, False if any exception occurs during the authentication or API call process. The return value can be used to conditionally proceed with further operations or halt execution.

Usage Example

import asyncio
from mixed_cloud_processor import create_remarkable_session

async def test_remarkable_auth():
    """Test reMarkable Cloud authentication"""
    print("🔐 Testing reMarkable Cloud authentication...")
    
    try:
        session = create_remarkable_session()
        print("✅ reMarkable authentication successful")
        
        response = session.get("https://eu.tectonic.remarkable.com/sync/v4/root")
        if response.status_code == 200:
            print("✅ reMarkable API access confirmed")
            root_data = response.json()
            print(f"📊 Root hash: {root_data.get('hash', 'N/A')[:16]}...")
        else:
            print(f"⚠️ reMarkable API call failed: HTTP {response.status_code}")
        
        return True
        
    except Exception as e:
        print(f"❌ reMarkable authentication failed: {e}")
        return False

# Run the test
if __name__ == "__main__":
    result = asyncio.run(test_remarkable_auth())
    print(f"Authentication test result: {result}")

Best Practices

• This function should be run using asyncio.run() or within an existing async context
• Ensure reMarkable Cloud credentials are properly configured before calling this function
• The function prints status messages to console, so it's best used in CLI/testing contexts rather than production APIs
• Handle the boolean return value to determine if subsequent reMarkable operations should proceed
• The function catches all exceptions broadly, which is appropriate for testing but may hide specific error details
• Network connectivity to eu.tectonic.remarkable.com is required; consider adding timeout handling for production use
• The API endpoint used (sync/v4/root) may change with reMarkable API updates; verify endpoint compatibility
