Claude Code Auto-Fix: How to Build Your Own AI Code Fixer with NexaAPI

Claude Code Auto-Fixjust launched on Product Hunt and developers are going crazy for it. The tool watches your pull requests in the cloud, resolves CI failures and review comments automatically, and keeps your PR green until it's ready to merge.

It's brilliant. But here's the thing: you can build the exact same functionality yourself in under 10 minutes using NexaAPI— and you'll have 56+ AI models to choose from instead of just Claude.

Why Build Your Own?

Tutorial: Build Your Own AI Code Auto-Fixer

Step 1: Install the SDK

# Python
pip install nexaapi

# Node.js
npm install nexaapi

Step 2: Python Implementation

# pip install nexaapi
from nexaapi import NexaAPI

client = NexaAPI(api_key='YOUR_API_KEY')

def auto_fix_code(buggy_code: str, language: str = 'python'):
    """AI-powered code auto-fix using NexaAPI."""
    response = client.chat.completions.create(
        model='gpt-4o',  # or claude-3-5-sonnet, gemini-pro — 56+ models!
        messages=[
            {
                'role': 'system',
                'content': f'Expert {language} developer. Find ALL bugs, fix them, return corrected code with inline comments.'
            },
            {
                'role': 'user',
                'content': f'Auto-fix this {language} code:\n\n{buggy_code}'
            }
        ],
        temperature=0.1
    )
    return response.choices[0].message.content

# Example: Fix a Python bug
buggy_code = '''
def calculate_average(numbers):
    return sum(numbers) / len(numbers)  # Bug: ZeroDivisionError if empty!
'''

fixed = auto_fix_code(buggy_code)
print(fixed)

Step 3: JavaScript Implementation

// npm install nexaapi
import NexaAPI from 'nexaapi';

const client = new NexaAPI({ apiKey: 'YOUR_API_KEY' });

async function autoFixCode(buggyCode, language = 'javascript') {
  const response = await client.chat.completions.create({
    model: 'gpt-4o',  // 56+ models available on NexaAPI
    messages: [
      {
        role: 'system',
        content: `Expert ${language} developer. Find and fix all bugs.`
      },
      {
        role: 'user',
        content: `Auto-fix this code:\n\n${buggyCode}`
      }
    ]
  });
  return response.choices[0].message.content;
}

// Test it
const buggy = `
function divide(a, b) {
  return a / b; // Bug: no zero check!
}
`;

autoFixCode(buggy).then(console.log);
