Universal API Integration

Costa Code provides an OpenAI-compatible API that works with virtually any AI agent, custom application, or automation tool. This allows you to integrate enterprise-grade AI capabilities into your existing workflows while maintaining the highest security standards.

​
API Configuration

​
Base Configuration

export COSTA_API_KEY="REPLACE_WITH_YOUR_COSTA_API_KEY"
export COSTA_BASE_URL="https://ai.costa.app/api/v1"
export COSTA_MODEL="costa/auto"

​
Integration Examples

​
Python SDK Integration

import openai

# Configure Costa Code as OpenAI provider
client = openai.OpenAI(
    api_key="costa_ent_your_key_here",
    base_url="https://ai.costa.app/api/v1"
)

# Basic chat completion
response = client.chat.completions.create(
    model="costa/enterprise-coder-v1",
    messages=[
        {"role": "user", "content": "Write a secure Python function for user authentication"}
    ],
    max_tokens=1000,
    temperature=0.7
)

print(response.choices[0].message.content)

# With enterprise security headers
response = client.chat.completions.create(
    model="costa/secure-claude-3-5-sonnet",
    messages=[
        {"role": "user", "content": "Review this code for security vulnerabilities"}
    ],
    extra_headers={
        "Costa-Security-Level": "maximum",
        "Costa-Data-Residency": "us-east",
        "Costa-Audit-Enabled": "true",
        "Costa-Zero-Retention": "true"
    }
)

​
JavaScript/Node.js Integration

import OpenAI from 'openai';

// Configure Costa Code client
const openai = new OpenAI({
  apiKey: 'costa_ent_your_key_here',
  baseURL: 'https://ai.costa.app/api/v1'
});

// Basic completion
async function generateCode(prompt) {
  const completion = await openai.chat.completions.create({
    model: 'costa/enterprise-coder-v1',
    messages: [{ role: 'user', content: prompt }],
    max_tokens: 1000,
    temperature: 0.7
  });
  
  return completion.choices[0].message.content;
}

// Enterprise security completion
async function secureGeneration(prompt, securityLevel = 'high') {
  const completion = await openai.chat.completions.create({
    model: 'costa/secure-claude-3-5-sonnet',
    messages: [{ role: 'user', content: prompt }],
    max_tokens: 1500,
    extra_headers: {
      'Costa-Security-Level': securityLevel,
      'Costa-Audit-Enabled': 'true',
      'Costa-Data-Residency': 'us-east'
    }
  });
  
  return completion.choices[0].message.content;
}

// Usage
const code = await generateCode('Create a REST API for user management');
const secureCode = await secureGeneration('Review this payment processing code', 'maximum');

Best Practices

1

Authentication Security

  • Store API keys securely using environment variables
  • Rotate API keys regularly
  • Use different keys for development and production
2

Error Handling

  • Implement comprehensive error handling
  • Add retry logic for transient failures
  • Log errors for debugging and monitoring
3

Security Configuration

  • Use appropriate security levels for your use case
  • Enable audit logging for compliance requirements
  • Configure data residency based on regulations
4

Performance Optimization

  • Use streaming for real-time applications
  • Cache responses when appropriate
  • Monitor usage and optimize model selection
Enterprise Integration: When integrating Costa Code with AI agents, ensure proper security measures are implemented including secure API key storage, appropriate security levels, and compliance configuration for your industry requirements.
