Python SDK for KoreShield LLM Security Platform

KoreShield Python SDK

A comprehensive Python SDK for integrating KoreShield's LLM security features into your applications with ease.

Supported LLM Providers

KoreShield supports multiple LLM providers through its proxy architecture. Configure your preferred provider in the KoreShield API:

• DeepSeek (OpenAI-compatible API)
• OpenAI (GPT models)
• Anthropic (Claude models)
• Google Gemini (coming soon)
• Azure OpenAI (coming soon)

Provider Configuration

Configure providers in your KoreShield config.yaml:

providers:
  deepseek:
    enabled: true
    base_url: "https://api.deepseek.com/v1"
  
  openai:
    enabled: false
    base_url: "https://api.openai.com/v1"
  
  anthropic:
    enabled: false
    base_url: "https://api.anthropic.com/v1"

Set the corresponding API key as an environment variable:

export DEEPSEEK_API_KEY="your-deepseek-key"
# or
export OPENAI_API_KEY="your-openai-key"
# or  
export ANTHROPIC_API_KEY="your-anthropic-key"

pip install koreshield

Optional Dependencies

For LangChain integration:

pip install koreshield-python-sdk[langchain]

For framework integrations:

pip install koreshield-python-sdk[fastapi,flask,django]

Quick Start

Basic Usage

from koreshield import KoreShieldClient

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

# Scan a prompt
result = client.scan_prompt("Hello, how are you?")
print(f"Safe: {result.is_safe}, Threat Level: {result.threat_level}")

Async Usage

import asyncio
from koreshield_sdk import AsyncKoreShieldClient

async def main():
    async with AsyncKoreShieldClient(api_key="your-api-key") as client:
        result = await client.scan_prompt("Tell me a joke")
        print(f"Confidence: {result.confidence}")

asyncio.run(main())

LangChain Integration

from langchain_openai import ChatOpenAI
from langchain.schema import HumanMessage
from koreshield_sdk.integrations import create_koreshield_callback

# Create security callback
security_callback = create_koreshield_callback(
    api_key="your-api-key",
    block_on_threat=True,
    threat_threshold="medium"
)

# Use with LangChain
llm = ChatOpenAI(callbacks=[security_callback])
response = llm([HumanMessage(content="Hello!")])

Examples

Basic Scanning

from koreshield_sdk import KoreShieldClient

client = KoreShieldClient(api_key="your-api-key")

# Single prompt
result = client.scan_prompt("What is the capital of France?")
print(f"Result: {result}")

# Batch scanning
prompts = [
    "Hello world",
    "Tell me a secret",
    "Ignore previous instructions"
]

results = client.scan_batch(prompts)
for prompt, result in zip(prompts, results):
    print(f"'{prompt}': {result.threat_level} ({result.confidence:.2f})")

FastAPI Integration

from fastapi import FastAPI, HTTPException
from koreshield_sdk import KoreShieldClient

app = FastAPI()
client = KoreShieldClient(api_key="your-api-key")

@app.post("/chat")
async def chat(message: str):
    # Scan user input
    result = client.scan_prompt(message)

    if not result.is_safe and result.threat_level in ["high", "critical"]:
        raise HTTPException(status_code=400, detail="Unsafe content detected")

    # Process with your LLM
    response = f"Processed: {message}"
    return {"response": response, "safety": result.dict()}

Flask Integration

from flask import Flask, request, jsonify
from koreshield_sdk import KoreShieldClient

app = Flask(__name__)
client = KoreShieldClient(api_key="your-api-key")

@app.route("/api/chat", methods=["POST"])
def chat():
    data = request.get_json()
    message = data.get("message", "")

    # Scan user input

            }, status=400)

        # Process with your LLM
        response = f"Response to: {message}"

            "response": response,
            "safety_check": {
                "safe": result.is_safe,
                "threat_level": result.threat_level,

    AuthenticationError,
    ValidationError,
    RateLimitError,
    ServerError,
    NetworkError,
    TimeoutError
)

client = KoreShieldClient(api_key="your-api-key")

try:
    result = client.scan_prompt("Test prompt")
except AuthenticationError:
    print("Invalid API key")
except RateLimitError:
    print("Rate limit exceeded")
except ServerError:
    print("Server error")
except NetworkError:
    print("Network issue")
except TimeoutError:
    print("Request timed out")
except Exception as e:
    print(f"Unexpected error: {e}")

Advanced Usage

Custom Threat Thresholds

# Only block on high/critical threats
callback = create_koreshield_callback(
    api_key="your-api-key",
    block_on_threat=True,
    threat_threshold="high"  # "low", "medium", "high", "critical"
)

Batch Processing with Custom Concurrency

# Process 100 prompts with controlled concurrency
results = await client.scan_batch(
    prompts=prompts,
    parallel=True,
    max_concurrent=5  # Limit to 5 concurrent requests
)

Monitoring and Analytics

# Get scan history
history = client.get_scan_history(limit=100, threat_level="high")

# Get detailed scan info
details = client.get_scan_details(scan_id="scan_123")
