Realtime API Tester
This tool allows you to test the availability and functionality of OpenAI's Realtime API and OpenAI-compatible services. You can verify API key permissions, test WebSocket connectivity, and send test messages to ensure everything is working correctly.
Security Warning: This tester runs in your browser and exposes your API key in the WebSocket connection. This method is ONLY for testing purposes and should NEVER be used in production. For production use, implement a secure relay server to handle authentication.
Test Interface
Configure your API endpoint and key to test the realtime service availability.
Click to quickly fill in common service endpoints:
The base URL of the API service (without /v1 or paths)
Your API key for authentication
Select the realtime model to test
How This Tester Works
This tester checks a realtime API service in these steps:
- Validates the API key format and checks basic API access
- Queries available models to confirm realtime model access
- Establishes a WebSocket connection to the realtime endpoint
- Creates a session with the realtime API
- Sends a test message and validates the response
Supported Services
This tester works with the following services:
- OpenAI Realtime API (official)
- CometAPI (OpenAI-compatible)
- Kizuna AI API (OpenAI-compatible)
- Any OpenAI-compatible realtime service
Security Note
This tester uses the 'openai-insecure-api-key' WebSocket protocol for browser-based testing, which exposes your API key. This is ONLY suitable for testing and development. For production applications, always use a secure relay server to protect your API credentials.
