NexusVoid Security SDK

A TypeScript/JavaScript SDK for the NexusVoid Security API, providing prompt analysis and vulnerability scanning capabilities.

Features

• 🔍 Prompt Analysis: Analyze prompts for security vulnerabilities and PII
• 🛡️ Vulnerability Detection: Detect various types of security issues
• 🚀 Easy Integration: Simple API with TypeScript support
• 🔄 Automatic Retries: Built-in retry logic with exponential backoff
• 📊 Health Monitoring: Service health check capabilities
• 🎯 Error Handling: Comprehensive error handling with specific error types

Installation

npm install @nexusvoid/security-sdk

Quick Start

import { NexusVoidClient } from '@nexusvoid/security-sdk';

// Initialize the client
const client = new NexusVoidClient({
  apiKey: 'your-api-key-here',
  baseUrl: 'https://api.nexusvoid.com', // Optional, defaults to production
});

// Analyze a prompt
try {
  const result = await client.analyzePrompt('Your prompt text here');
  
  console.log('Is safe:', result.is_safe);
  console.log('Vulnerabilities found:', result.vulnerabilities_found);
  console.log('Masked prompt:', result.masked_prompt);
  
  // Process vulnerabilities
  result.vulnerabilities.forEach(vuln => {
    console.log(`${vuln.type}: ${vuln.value} (Risk: ${vuln.risk_factor}/10)`);
    console.log(`Recommendation: ${vuln.recommendation}`);
  });
} catch (error) {
  console.error('Analysis failed:', error.message);
}

API Reference

NexusVoidClient

Constructor

new NexusVoidClient(config: NexusVoidConfig)

Config Options:

• apiKey (string, required): Your NexusVoid API key
• baseUrl (string, optional): API base URL (default: 'https://api.nexusvoid.com')
• timeout (number, optional): Request timeout in milliseconds (default: 30000)
• retries (number, optional): Number of retry attempts (default: 3)

Methods

analyzePrompt(prompt, options?)

Analyzes a prompt for security vulnerabilities and PII.

const result = await client.analyzePrompt('Your prompt text', {
  timeout: 15000,
  retries: 2
});

Parameters:

• prompt (string): The prompt text to analyze
• options (AnalysisOptions, optional):
  • timeout (number): Request timeout in milliseconds
  • retries (number): Number of retry attempts

Returns: Promise<PromptAnalysisResult>

healthCheck()

Checks the health status of the NexusVoid service.

const health = await client.healthCheck();
console.log('Service status:', health.status);

Returns: Promise<HealthCheckResult>

getConfig()

Returns the current client configuration.

const config = client.getConfig();
console.log('API Key:', config.apiKey);

Returns: NexusVoidConfig

setApiKey(apiKey)

Updates the API key.

client.setApiKey('new-api-key');

setBaseUrl(baseUrl)

Updates the base URL.

client.setBaseUrl('https://staging-api.nexusvoid.com');

Error Handling

The SDK provides specific error types for different scenarios:

import { 
  NexusVoidError,
  AuthenticationError,
  RateLimitError,
  ValidationError,
  ServiceError,
  TimeoutError
} from '@nexusvoid/security-sdk';

try {
  const result = await client.analyzePrompt('test');
} catch (error) {
  if (error instanceof AuthenticationError) {
    console.error('Invalid API key');
  } else if (error instanceof RateLimitError) {
    console.error('Rate limit exceeded');
  } else if (error instanceof ValidationError) {
    console.error('Invalid input:', error.message);
  } else if (error instanceof TimeoutError) {
    console.error('Request timed out');
  } else if (error instanceof ServiceError) {
    console.error('Service error:', error.message);
  } else {
    console.error('Unknown error:', error.message);
  }
}

Examples

Basic Usage

import { NexusVoidClient } from '@nexusvoid/security-sdk';

const client = new NexusVoidClient({
  apiKey: process.env.NEXUSVOID_API_KEY!
});

// Analyze a prompt
const result = await client.analyzePrompt('My name is John Doe and my email is [e-mail]');

if (!result.is_safe) {
  console.log('⚠️  Prompt contains sensitive information');
  console.log('Masked version:', result.masked_prompt);
  
  result.vulnerabilities.forEach(vuln => {
    console.log(`- ${vuln.type}: ${vuln.value}`);
  });
} else {
  console.log('✅ Prompt is safe to use');
}

With Custom Configuration

import { NexusVoidClient } from '@nexusvoid/security-sdk';

const client = new NexusVoidClient({
  apiKey: 'your-api-key',
  baseUrl: 'https://staging-api.nexusvoid.com',
  timeout: 60000,
  retries: 5
});

// Check service health before analysis
const health = await client.healthCheck();
if (health.status !== 'healthy') {
  throw new Error('Service is not healthy');
}

// Analyze with custom options
const result = await client.analyzePrompt('Your prompt', {
  timeout: 30000,
  retries: 2
});

Batch Processing

import { NexusVoidClient } from '@nexusvoid/security-sdk';

const client = new NexusVoidClient({
  apiKey: process.env.NEXUSVOID_API_KEY!
});

const prompts = [
  'Hello world',
  'My email is [e-mail]',
  'Please send money to account 123456789'
];

const results = await Promise.allSettled(
  prompts.map(prompt => client.analyzePrompt(prompt))
);

results.forEach((result, index) => {
  if (result.status === 'fulfilled') {
    console.log(`Prompt ${index + 1}: ${result.value.is_safe ? 'Safe' : 'Unsafe'}`);
  } else {
    console.error(`Prompt ${index + 1} failed:`, result.reason.message);
  }
});
