AI API Test Hub

AI API Test Hub is a comprehensive application designed for testing and verifying connectivity with various AI model APIs. It provides a simple interface to test API connections, execute manual testing, and access API code snippets for integration.

Features

• Universal AI API Testing: Test connections to multiple AI providers including OpenAI, Google, Anthropic, and DeepSeek
• Model Discovery: Browse through models organized by company with detailed information
• Connection Verification: Quickly verify API key validity and connectivity
• Manual Testing: Send custom prompts to test model responses
• Code Snippets: Access ready-to-use code examples for API integration in multiple languages
• Responsive Design: Clean, modern UI that works across devices

Project Structure

The project is organized into two main directories:

• frontend/: React-based user interface
• backend/: Node.js/Express API server

Tech Stack

Frontend

• React
• React Router
• Syntax Highlighter
• Modern CSS (with variables and flexbox/grid)

Backend

• Node.js
• Express
• Axios (for API requests)

Setup and Installation

Prerequisites

• Node.js (v14+)
• npm or yarn

Backend Setup

1. Navigate to the backend directory:

   cd ai-api-tester/backend
   

2. Install dependencies:

   npm install
   

3. Create a .env file with your configuration:

   PORT=5000
   NODE_ENV=development
   

4. Start the server:

   npm start
   

Frontend Setup

1. Navigate to the frontend directory:

   cd ai-api-tester/frontend
   

2. Install dependencies:

   npm install
   

3. Create a .env file:

   REACT_APP_API_URL=http://localhost:5000/api
   

4. Start the development server:

   npm start
   

Usage

Home Page

• Browse available AI companies and models
• Search for specific models by name

Company Page

• View all models available from a specific company
• Models are grouped by category (chat, image, etc.)

Model Page

• View detailed information about a specific model
• Test API connection with your API key
• Try manual testing with custom prompts
• Access code snippets for integration

API Endpoints

Model Endpoints

• GET /api/companies: Get all companies with basic model info
• GET /api/companies/:companyId: Get detailed info for a specific company
• GET /api/models: Get all models (simplified info)
• GET /api/models/:modelId: Get detailed info for a specific model

Test Endpoints

• POST /api/test/connection: Test API connection
  • Request body: { modelId, apiKey }
• POST /api/test/manual: Send a manual test request
  • Request body: { modelId, apiKey, prompt }

Adding New Models

The system is designed to be easily extensible. To add new models:

1. Update the models.json file in the backend/data directory
2. Add appropriate connector logic to apiConnectors.js if it's a new provider

Security Notes

• API keys are never stored on the server
• API keys are only used for the duration of the request
• All communication with AI provider APIs happens through the backend to avoid exposing API keys to the client

Future Enhancements

• Add authentication to save favorite models
• Implement history of test results
• Add support for more AI providers
• Create a comparison tool for different models
• Add batch testing capabilities
