apx-toolkit/docs/archive/WHAT-APX-DOES.md

Automatically discover APIs and generate complete integration packages: code in 12 languages, TypeScript types, test suites, SDK packages, API documentation, mock servers, performance reports, and contract tests. Saves 2-4 weeks of work in seconds.

# 🎯 What APX Does - Simple Explanation

## The Problem It Solves

**Before APX:** When you want to integrate with an API, you have to:
1. 🔍 Manually discover API endpoints (trial and error)
2. 📝 Write code to call the API (hours of work)
3. 📘 Create TypeScript types manually (error-prone)
4. 🧪 Write tests (more hours)
5. 📚 Document the API (tedious)
6. 🔄 Repeat for each language you need

**Time:** Days or weeks of work

## What APX Does Automatically

APX watches a website or API, discovers all the endpoints, and generates **everything you need** in seconds:

### 1. 🔍 **API Discovery**
- Watches network traffic
- Finds all API endpoints automatically
- Detects pagination, authentication, data structures

### 2. 💻 **Code Generation (12 Languages)**
Generates ready-to-use code in:
- TypeScript
- JavaScript
- Python
- Go
- Java
- C#
- PHP
- Ruby
- Swift
- Kotlin
- Rust
- Dart

**Example Output:**
```typescript
// APX automatically generated this:
const response = await fetch('https://api.example.com/posts', {
  method: 'GET',
  headers: { 'Content-Type': 'application/json' }
});
const data = await response.json();
```

### 3. 📘 **TypeScript Types**
Automatically creates type definitions:
```typescript
interface Post {
  id: number;
  title: string;
  body: string;
  userId: number;
}
```

### 4. 🧪 **Test Suites (5 Frameworks)**
Generates tests for:
- Jest
- Mocha
- Vitest
- Playwright
- Cypress

### 5. 📦 **SDK Packages**
Complete SDK packages for:
- TypeScript/Node.js
- Python
- Go

### 6. 📚 **API Documentation**
Generates documentation in:
- OpenAPI/Swagger
- Postman collection
- cURL commands
- Insomnia collection

### 7. 🔒 **Security Reports**
- Identifies security issues
- Suggests best practices
- Checks for vulnerabilities

### 8. 🔄 **GitHub Actions**
Auto-generates CI/CD workflows for automated API discovery

## Real-World Example

**Scenario:** You want to integrate with a new API

### Without APX:
1. Spend 2-3 days reading API docs
2. Write code manually (4-8 hours)
3. Create types (2-3 hours)
4. Write tests (3-4 hours)
5. Create documentation (2-3 hours)
6. **Total: 2-3 weeks**

### With APX:
1. Point APX at the API (30 seconds)
2. Wait for generation (1-2 minutes)
3. Copy generated code (1 minute)
4. **Total: 2-3 minutes**

**Time Saved: 2-3 weeks → 2-3 minutes**
