Laravel + Claude AI for API Documentation: Auto‑Generated Swagger + Guides

API documentation is often the most neglected part of software development. Developers love writing code, but few enjoy maintaining Swagger specs, updating guides, or keeping docs in sync with evolving endpoints. Yet, for SaaS platforms, APIs, and enterprise integrations, clear documentation is as critical as the code itself.

Enter Laravel + Claude AI. By combining Laravel’s expressive framework with Claude’s natural language generation capabilities, you can auto‑generate Swagger documentation and developer guides directly from your codebase. This not only saves time but ensures your docs are always accurate, consistent, and developer‑friendly.

🚀 Why Laravel + Claude?

• Laravel strengths: Elegant routing, middleware, and resource controllers make APIs easy to build.
• Claude AI strengths: Context‑aware language generation, summarization, and structured output capabilities.
• Together: Claude can read Laravel routes, controllers, and annotations, then generate Swagger/OpenAPI specs and human‑readable guides automatically.

This means less manual YAML editing, fewer outdated docs, and more time spent building features.

🔑 Key Benefits

1. Auto‑Generated Swagger Specs
   Claude parses Laravel routes and controllers, then outputs OpenAPI JSON/YAML.
2. Human‑Readable Guides
   Claude transforms technical specs into developer‑friendly tutorials and quick‑start guides.
3. Always in Sync
   Docs update automatically when routes or controllers change.
4. Multi‑Format Output
   Swagger for machines, Markdown/HTML for humans.

🛠️ Setting Up Laravel + Claude AI

Step 1: Install Swagger Tools

Use a Laravel package like darkaonline/l5-swagger or goldspecdigital/laravel-swagger to bootstrap Swagger integration.

composer require darkaonline/l5-swagger

Step 2: Annotate Controllers

Add Swagger annotations to your Laravel controllers.

/**
 * @OA\Get(
 *     path="/api/users",
 *     summary="Get list of users",
 *     @OA\Response(response=200, description="Successful response")
 * )
 */
public function index()
{
    return User::all();
}

Step 3: Integrate Claude AI

Use Claude’s API to process your Laravel routes and annotations.

use Anthropic\Claude;

$claude = new Claude(env('CLAUDE_API_KEY'));

$swaggerSpec = $claude->generateSwaggerFromRoutes(Route::getRoutes());
$guide = $claude->generateGuideFromSwagger($swaggerSpec);

🧪 Example: Auto‑Generated Swagger

Suppose you have a simple Laravel API:

Route::get('/api/posts', [PostController::class, 'index']);
Route::post('/api/posts', [PostController::class, 'store']);

Claude can generate the following Swagger spec:

openapi: 3.0.0
info:
  title: Laravel Blog API
  version: 1.0.0
paths:
  /api/posts:
    get:
      summary: Retrieve all posts
      responses:
        '200':
          description: Successful response
    post:
      summary: Create a new post
      requestBody:
        required: true
        content:
          application/json:
            schema:
              $ref: '#/components/schemas/Post'
      responses:
        '201':
          description: Post created

---

📖 Example: Auto‑Generated Guide

Claude can also generate a developer guide from the Swagger spec:

# Laravel Blog API Guide

## Retrieve All Posts
**Endpoint:** `GET /api/posts`  
Returns a list of blog posts in JSON format.

### Example Request
```bash
curl -X GET https://yourapp.com/api/posts

Example Response

[
  { "id": 1, "title": "First Post", "content": "Hello World" }
]

---

🧩 Advanced Features

1. Enum Support

Claude can detect Laravel enums and include them in Swagger schemas.

enum Status: string {
    case Draft = 'draft';
    case Published = 'published';
}

Swagger output:

status:
  type: string
  enum: [draft, published]

---

2. Authentication Integration

Claude can parse Laravel’s auth:api middleware and document authentication requirements.

securitySchemes:
  bearerAuth:
    type: http
    scheme: bearer

---

3. Error Handling

Claude can generate error response docs based on Laravel’s exception handlers.

responses:
  '401':
    description: Unauthorized
  '404':
    description: Resource not found
