🚀 Automatic API Generator

A web-based tool to quickly generate and serve custom API endpoints using a simple UI. Define endpoints, methods, and responses, and the backend will serve them instantly—no coding required!

Features

• Dynamic API Creation: Add multiple endpoints with custom methods and responses.
• Supports GET & POST: Define GET (JSON or text response) and POST (JSON schema) endpoints.
• Persistent Storage: Endpoints are saved in urls.json and persist across server restarts.
• Live Feedback: User-friendly error messages for invalid input.
• View All Endpoints: Easily view all configured endpoints via /endpoints.

Error Handling

• If you send invalid JSON to the backend, you'll get:

  {
    "success": false,
    "error": "Invalid JSON: Please send a valid JSON body."
  }

• The UI provides live feedback for JSON validation and server errors.

---

Customization

• You can extend supported HTTP methods by editing the frontend and backend.
• To reset all endpoints, clear the urls.json file.
