Integration Guide

This comprehensive guide provides enterprise-grade strategies and patterns for integrating RunAnythingAI's APIs across web, mobile, and backend environments. Learn how to implement character-driven AI features that scale with your application architecture and deliver exceptional user experiences.

Integration Strategy Overview

Before diving into specific framework implementations, consider these architectural approaches:

Integration Patterns

Pattern	Description	Best For
Backend Proxy	Route all AI requests through a server backend	Security, rate limiting, logging
Direct Client	Connect directly from client to RunAnythingAI	Prototyping, simple applications
Hybrid	Core logic on backend with stream forwarding	Real-time experiences with security
Serverless	Function-as-a-Service mediating AI requests	Scalable, event-driven applications

Key Integration Decisions

1. Authentication Management: Determine where API keys will be stored and managed
2. Caching Strategy: Identify opportunities for response caching and reuse
3. Error Handling: Design graceful degradation paths for API unavailability
4. Scaling Approach: Plan for concurrent requests during high-traffic periods
5. Performance Budget: Set response time targets and optimization strategies

Web Frameworks

React Integration

Here's how to create a simple character chat component in React:

import React, { useState, useEffect, useRef } from 'react';
import './CharacterChat.css';

const CharacterChat = ({ apiKey, characterPersona, characterName }) => {
  const [messages, setMessages] = useState([]);
  const [input, setInput] = useState('');
  const [isLoading, setIsLoading] = useState(false);
  const [audioUrl, setAudioUrl] = useState(null);
  const audioPlayer = useRef(null);
  const messagesEndRef = useRef(null);

  const scrollToBottom = () => {
    messagesEndRef.current?.scrollIntoView({ behavior: 'smooth' });
  };

  useEffect(() => {
    scrollToBottom();
  }, [messages]);

  const sendMessage = async () => {
    if (!input.trim()) return;
    
    // Add user message to chat
    const userMessage = {
      id: `user-${Date.now()}`,
      messageIndex: messages.length,
      chatId: 'chat-session',
      userId: 'user-id',
      content: input,
      createdAt: new Date().toISOString(),
      role: 'You',
      index: messages.length
    };
    
    setMessages(prev => [...prev, userMessage]);
    setInput('');
    setIsLoading(true);
    
    try {
      // Step 1: Generate character response
      const genResponse = await fetch('https://api.runanythingai.com/api/text/Witch', {
        method: 'POST',
        headers: {
          'Content-Type': 'application/json',
          'Authorization': `Bearer ${apiKey}`
        },
        body: JSON.stringify({
          messages: [...messages, userMessage].map(msg => ({
            ...msg,
            upvote: 0,
            image: null
          })),
          persona: characterPersona,
          botName: characterName,
          samplingParams: { max_tokens: 150 }
        })
      });
      
      const { id } = await genResponse.json();
      
      // Step 2: Poll for completion
      let completed = false;
      let characterResponse;
      
      while (!completed) {
        const statusResponse = await fetch(`https://api.runanythingai.com/api/v2/status/${id}`, {
          headers: {
            'Authorization': `Bearer ${apiKey}`
          }
        });
        
        const statusData = await statusResponse.json();
        
        if (statusData.status === 'completed') {
          completed = true;
          characterResponse = statusData.reply;
        } else if (statusData.status === 'error') {
          throw new Error(`Generation failed: ${statusData.error}`);
        } else {
          await new Promise(resolve => setTimeout(resolve, 1000));
        }
      }
      
      // Add character response to chat
      const botMessage = {
        id: `bot-${Date.now()}`,
        messageIndex: messages.length + 1,
        chatId: 'chat-session',
        userId: 'bot-id',
        content: characterResponse,
        createdAt: new Date().toISOString(),
        role: 'Bot',
        index: messages.length + 1

      setMessages(prev => [...prev, botMessage]);
      
      // Step 3: Generate audio for the character's response
      const ttsResponse = await fetch('https://api.runanythingai.com/api/audio/full', {
        method: 'POST',
        headers: {
          'Content-Type': 'application/json',
          'Authorization': `Bearer ${apiKey}`
        },
        body: JSON.stringify({

          voice: "af_nicole",
          speed: 1
        })
      });
      
      if (ttsResponse.ok) {
        const audioBlob = await ttsResponse.blob();
        const url = URL.createObjectURL(audioBlob);
        setAudioUrl(url);
        
        // Play audio automatically
        if (audioPlayer.current) {
          audioPlayer.current.src = url;
          audioPlayer.current.play();
        }
      }
    } catch (error) {
      console.error('Error:', error);
      setMessages(prev => [...prev, {
        id: `error-${Date.now()}`,
        messageIndex: messages.length + 1,
        chatId: 'chat-session',
        userId: 'system',
        content: 'Sorry, something went wrong. Please try again.',
        createdAt: new Date().toISOString(),
        role: 'System',
        index: messages.length + 1
      }]);
    } finally {
      setIsLoading(false);
    }
  };

  return (
    <div className="character-chat">
      <div className="chat-history">
        {messages.map((msg, index) => (
          <div 
            key={msg.id} 
            className={`message ${msg.role.toLowerCase()}`}
          >
            <div className="message-content">{msg.content}</div>
          </div>
        ))}
        {isLoading && (
          <div className="message bot loading">
            <div className="typing-indicator">
              <span></span>
              <span></span>
              <span></span>

          </div>
        )}
        <div ref={messagesEndRef} />
      </div>

          onKeyPress={(e) => e.key === 'Enter' && sendMessage()}
          placeholder="Type your message..."
          disabled={isLoading}
        />
        <button onClick={sendMessage} disabled={isLoading}>

      </div>
      
      <audio ref={audioPlayer} style={{ display: 'none' }} controls />
    </div>
  );
};

export default CharacterChat;

Usage in a parent component:

import CharacterChat from './CharacterChat';

function App() {
  const characterPersona = `Emma's Persona: Emma is a friendly AI assistant with expertise in 
  technology topics. She has a cheerful demeanor and likes to use examples to explain complex 
  concepts. Emma occasionally uses tech-related metaphors and has a slight tendency to get 
  excited about innovations.`;

  return (
    <div className="App">
      <h1>Chat with Emma</h1>
      <CharacterChat 
        apiKey="YOUR_API_KEY" 
        characterPersona={characterPersona}
        characterName="Emma"
      />
    </div>
  );
}

Vue.js Integration

Here's how to create a character chat component in Vue.js:

<template>
  <div class="character-chat">
    <div class="chat-messages" ref="chatContainer">
      <div
        v-for="(message, index) in messages"
        :key="index"
        :class="['message', message.role.toLowerCase()]"
      >
        {{ message.content }}
      </div>
      <div v-if="isLoading" class="message bot typing">
        <span></span><span></span><span></span>
      </div>
    </div>
    
    <div class="chat-input">
      <input
        v-model="userInput"
        @keyup.enter="sendMessage"
        placeholder="Type your message..."
        :disabled="isLoading"
      />
      <button @click="sendMessage" :disabled="isLoading">
        {{ isLoading ? 'Sending...' : 'Send' }}
      </button>
    </div>
    
    <audio ref="audioPlayer" style="display: none"></audio>
  </div>
</template>

Mobile Integration

React Native

Here's a simplified example of integrating RunAnythingAI with React Native for a mobile character chat app:

import React, { useState, useEffect, useRef } from 'react';

  Text,
  TextInput,
  TouchableOpacity,
  FlatList,

Server-Side Integration

Node.js Express Server

You can also integrate RunAnythingAI on the server side to handle API keys securely:

const express = require('express');
const cors = require('cors');
const fetch = require('node-fetch');
const app = express();
const port = process.env.PORT || 3000;

// Replace with your API key from environment variables
const API_KEY = process.env.RUNANYTHING_API_KEY;

app.use(cors());
app.use(express.json());

// Endpoint to generate character responses
app.post('/api/character-response', async (req, res) => {
  try {
    const { messages, persona, characterName } = req.body;
    
    const genResponse = await fetch('https://api.runanythingai.com/api/text/Witch', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
        'Authorization': `Bearer ${API_KEY}`
      },
      body: JSON.stringify({
        messages,
        persona,
        botName: characterName,
        samplingParams: { max_tokens: 150 }
      })
    });
    
    const data = await genResponse.json();
    res.json({ id: data.id });
  } catch (error) {
    console.error('Error generating response:', error);
    res.status(500).json({ error: 'Failed to generate response' });
  }
});

// Status checking endpoint
app.get('/api/status/:id', async (req, res) => {
  try {
    const { id } = req.params;
    
    const statusResponse = await fetch(`https://api.runanythingai.com/api/v2/status/${id}`, {
      headers: {
        'Authorization': `Bearer ${API_KEY}`
      }
    });
    
    const statusData = await statusResponse.json();
    res.json(statusData);
  } catch (error) {
    console.error('Error checking status:', error);
    res.status(500).json({ error: 'Failed to check status' });
  }
});

// Text-to-speech endpoint
app.post('/api/tts', async (req, res) => {
  try {
    const { text, voice, speed } = req.body;
    
    const ttsResponse = await fetch('https://api.runanythingai.com/api/audio/full', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
        'Authorization': `Bearer ${API_KEY}`
      },
      body: JSON.stringify({
        text,
        voice: voice || 'af_nicole',
        speed: speed || 1
      })
    });
    
    if (!ttsResponse.ok) {
      throw new Error(`TTS API error: ${await ttsResponse.text()}`);
    }
    
    // Pipe the audio response directly to the client
    ttsResponse.body.pipe(res);
  } catch (error) {
    console.error('Error generating TTS:', error);
    res.status(500).json({ error: 'Failed to generate speech' });
  }
});

app.listen(port, () => {
  console.log(`Server listening at http://localhost:${port}`);
});

Authentication and Security

Secure access to RunAnythingAI APIs through these best practices:

Secure API Key Management

Never expose API keys in client-side code. Instead, implement a backend token service:

// Express.js API Key Management Service
const express = require('express');
const jwt = require('jsonwebtoken');
const rateLimit = require('express-rate-limit');
const app = express();

// Rate limiting to prevent token abuse
const limiter = rateLimit({
  windowMs: 15 * 60 * 1000, // 15 minutes
  max: 100, // limit each IP to 100 requests per windowMs
  standardHeaders: true,
  legacyHeaders: false
});

// Apply rate limiting to token issuance
app.use('/api/token', limiter);

// Environment variables for security
const API_KEY = process.env.RUNANYTHING_API_KEY;
const JWT_SECRET = process.env.JWT_SECRET;

// Token issuance endpoint (authenticate users first)
app.post('/api/token', authenticateUser, (req, res) => {
  // User is authenticated at this point
  const userContext = {
    userId: req.user.id,
    role: req.user.role,
    permissions: req.user.permissions,
    exp: Math.floor(Date.now() / 1000) + (60 * 15) // 15 minute expiration
  };
  
  // Sign client token that doesn't contain the API key
  const token = jwt.sign(userContext, JWT_SECRET);
  
  res.json({ token });
});

// Proxy endpoint for AI API calls
app.post('/api/proxy/text/:model', authenticateToken, (req, res) => {
  const { model } = req.params;
  const requestBody = req.body;
  
  // Add request validation, logging, and user context here
  
  // Forward to RunAnythingAI with your secured API key
  fetch(`https://api.runanythingai.com/api/text/${model}`, {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      'Authorization': `Bearer ${API_KEY}`
    },
    body: JSON.stringify(requestBody)
  })
  .then(apiRes => apiRes.json())
  .then(data => res.json(data))
  .catch(error => {
    console.error('API error:', error);
    res.status(500).json({ error: 'API request failed' });
  });
});

// JWT verification middleware
function authenticateToken(req, res, next) {
  const authHeader = req.headers['authorization'];
  const token = authHeader && authHeader.split(' ')[1];
  
  if (!token) return res.status(401).json({ error: 'Access token required' });
  
  jwt.verify(token, JWT_SECRET, (err, user) => {
    if (err) return res.status(403).json({ error: 'Invalid or expired token' });
    req.user = user;
    next();
  });
}

// Implement your user authentication logic
function authenticateUser(req, res, next) {
  // Your authentication implementation
}

app.listen(3000, () => {
  console.log('Security proxy server running on port 3000');
});

Request Signing and Verification

For high-security environments, implement request signing:

const crypto = require('crypto');

// Generate a signature for API requests
function signRequest(payload, timestamp, secretKey) {
  const data = JSON.stringify(payload) + timestamp;
  return crypto
    .createHmac('sha256', secretKey)
    .update(data)
    .digest('hex');
}

// Client-side request with signature
async function secureAPIRequest(endpoint, payload) {
  const timestamp = Date.now().toString();
  const signature = signRequest(payload, timestamp, CLIENT_SECRET);
  
  const response = await fetch(`/api/proxy/${endpoint}`, {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      'X-Timestamp': timestamp,
      'X-Signature': signature,
      'Authorization': `Bearer ${userToken}`
    },
    body: JSON.stringify(payload)
  });
  
  return response.json();
}

Content Security

Implement content filtering for user inputs and AI outputs:

// Content moderation middleware
function moderateContent(req, res, next) {
  const userContent = req.body.messages
    .filter(m => m.role === 'You')
    .map(m => m.content)
    .join(' ');
  
  // Check against banned words/patterns
  const bannedPatterns = [/offensive\s+term/i, /abusive\s+content/i];
  
  for (const pattern of bannedPatterns) {
    if (pattern.test(userContent)) {
      return res.status(400).json({
        error: 'Content policy violation detected',
        code: 'CONTENT_POLICY_VIOLATION'
      });
    }
  }
  
  next();
}

// Apply to API routes
app.post('/api/proxy/text/:model', authenticateToken, moderateContent, handleRequest);

Testing and Monitoring

Ensure reliability of your RunAnythingAI integration with comprehensive testing and monitoring strategies.

Automated Integration Testing

Example using Jest for testing character interactions:

// character-service.test.js
const axios = require('axios');
const MockAdapter = require('axios-mock-adapter');
const characterService = require('../services/character-service');

const mock = new MockAdapter(axios);

describe('Character Service Integration Tests', () => {
  // Reset mocks between tests
  afterEach(() => {
    mock.reset();
  });
  
  test('should handle successful character generation and TTS flow', async () => {
    // Mock generation request
    mock.onPost('https://api.runanythingai.com/api/text/Witch').reply(200, {
      id: 'mock-request-123'
    });
    
    // Mock status check - first processing, then completed
    mock.onGet('https://api.runanythingai.com/api/v2/status/mock-request-123')
      .replyOnce(200, { status: 'processing' })
      .replyOnce(200, { 
        status: 'completed',
        reply: 'This is a test character response.'
      });
    
    // Mock TTS response
    mock.onPost('https://api.runanythingai.com/api/audio/full')
      .reply(200, Buffer.from('mock-audio-data'), {
        'Content-Type': 'audio/mpeg'
      });
    
    // Test character interaction flow
    const result = await characterService.characterInteraction(
      'Witch',
      [{ role: 'You', content: 'Hello character', index: 0 }],
      'Test persona description',
      'TestBot'
    );
    
    // Assertions
    expect(result).toBeDefined();
    expect(result.text).toBe('This is a test character response.');
    expect(result.audio).toBeDefined();
  });
  
  test('should handle API errors gracefully', async () => {
    // Mock failed generation request
    mock.onPost('https://api.runanythingai.com/api/text/Witch').reply(429, {
      error: 'Rate limit exceeded'
    });
    
    // Test error handling
    await expect(characterService.characterInteraction(
      'Witch',
      [{ role: 'You', content: 'Hello character', index: 0 }],
      'Test persona description',
      'TestBot'
    )).rejects.toThrow(/Rate limit exceeded/);
  });
});

End-to-End Testing

For full end-to-end testing with Cypress:

// cypress/integration/character-chat.spec.js
describe('Character Chat Component', () => {
  beforeEach(() => {
    // Set up API mocks
    cy.intercept('POST', '/api/proxy/text/*', {
      statusCode: 200,
      body: { id: 'cypress-mock-id' }
    }).as('textGeneration');
    
    cy.intercept('GET', '/api/proxy/status/*', {
      statusCode: 200,
      body: { 
        status: 'completed',
        reply: 'This is a mock character response from Cypress.'
      }
    }).as('statusCheck');
    
    // Mock audio endpoint with a test MP3
    cy.intercept('POST', '/api/proxy/audio/full', {
      statusCode: 200,
      fixture: 'test-audio.mp3',
    }).as('ttsRequest');
    
    // Visit the chat page
    cy.visit('/character-chat');
  });
  
  it('should send message and display character response', () => {
    // Type and send a message
    cy.get('.chat-input input')
      .type('Hello, AI character!');
    
    cy.get('.chat-input button')
      .click();
    
    // Check that user message appears in chat
    cy.get('.message.user')
      .should('contain', 'Hello, AI character!');
    
    // Verify API calls
    cy.wait('@textGeneration');
    cy.wait('@statusCheck');
    
    // Verify character response displays
    cy.get('.message.bot')
      .should('contain', 'This is a mock character response from Cypress.');
    
    // Verify audio player appears and has src
    cy.get('audio')
      .should('exist')
      .and('have.attr', 'src')
      .should('include', 'blob:');
  });
  
  it('should show loading indicator while waiting for response', () => {
    // Override status check to first return processing
    cy.intercept('GET', '/api/proxy/status/*', {
      statusCode: 200,
      body: { status: 'processing' }
    }).as('processingCheck');
    
    // Type and send message
    cy.get('.chat-input input')
      .type('Are you still thinking?');
    cy.get('.chat-input button')
      .click();
    
    // Verify loading indicator appears
    cy.get('.typing-indicator')
      .should('be.visible');
    
    // Now return completed response
    cy.intercept('GET', '/api/proxy/status/*', {
      statusCode: 200,
      body: { 
        status: 'completed',
        reply: 'Yes, I was thinking, but now I have an answer.'
      }
    }).as('completedCheck');
    
    // Wait for completed response
    cy.wait('@completedCheck');
    
    // Verify loading indicator disappears and response appears
    cy.get('.typing-indicator')
      .should('not.exist');
    cy.get('.message.bot')
      .should('contain', 'Yes, I was thinking');
  });
});

Production Monitoring

Set up comprehensive monitoring for your RunAnythingAI integration:

// Monitor API performance and errors with OpenTelemetry
const { trace } = require('@opentelemetry/api');
const { Resource } = require('@opentelemetry/resources');
const { SemanticResourceAttributes } = require('@opentelemetry/semantic-conventions');
const { NodeTracerProvider } = require('@opentelemetry/sdk-trace-node');
const { SimpleSpanProcessor } = require('@opentelemetry/sdk-trace-base');
const { ZipkinExporter } = require('@opentelemetry/exporter-zipkin');

// Configure OpenTelemetry
const provider = new NodeTracerProvider({
  resource: new Resource({
    [SemanticResourceAttributes.SERVICE_NAME]: 'character-service',
  }),
});

// Configure exporter
const exporter = new ZipkinExporter({
  url: 'http://zipkin:9411/api/v2/spans',
  serviceName: 'character-service'
});

provider.addSpanProcessor(new SimpleSpanProcessor(exporter));
provider.register();

// Get tracer
const tracer = trace.getTracer('character-service-tracer');

// Instrumented character interaction function
async function monitoredCharacterInteraction(character, messages, persona, botName) {
  // Create a span for the entire operation
  return tracer.startActiveSpan('character-interaction', async (span) => {
    try {
      // Add context attributes
      span.setAttribute('character.type', character);
      span.setAttribute('message.count', messages.length);
      
      // Start text generation
      const generationStart = Date.now();
      span.addEvent('Starting text generation');
      
      // Step 1: Generate text with sub-span
      let generationSpan = tracer.startSpan('text-generation');
      generationSpan.setAttribute('character.model', character);
      
      const { id } = await sendGenerationRequest(character, messages, persona, botName);
      
      generationSpan.end();
      
      // Step 2: Poll with monitoring
      let pollSpan = tracer.startSpan('status-polling');
      const result = await pollStatus(id);
      
      pollSpan.setAttribute('polling.duration', Date.now() - generationStart);
      pollSpan.end();
      
      // Step 3: TTS with monitoring
      let ttsSpan = tracer.startSpan('text-to-speech');
      ttsSpan.setAttribute('tts.text_length', result.length);
      
      const audio = await generateSpeech(result);
      
      ttsSpan.end();
      
      // Record metrics
      span.setAttribute('total.duration', Date.now() - generationStart);
      
      return { text: result, audio };
    } catch (error) {
      span.recordException(error);
      span.setStatus({
        code: trace.SpanStatusCode.ERROR,
        message: error.message
      });
      throw error;
    } finally {
      span.end();
    }
  });
}

// Example health check endpoint for monitoring
app.get('/health', (req, res) => {
  Promise.all([
    checkAPIAccess('Witch'),
    checkDatabaseConnection(),
    checkCacheService()
  ])
  .then(([apiStatus, dbStatus, cacheStatus]) => {
    const allHealthy = apiStatus.healthy && dbStatus.healthy && cacheStatus.healthy;
    
    res.status(allHealthy ? 200 : 503).json({
      status: allHealthy ? 'healthy' : 'unhealthy',
      timestamp: new Date().toISOString(),
      services: {
        api: apiStatus,
        database: dbStatus,
        cache: cacheStatus
      }
    });

  .catch(error => {
    res.status(500).json({
      status: 'error',
      message: error.message
