What it does

AIClient2API acts as a self-hosted proxy to manage and route requests to multiple AI providers, including OpenAI, Claude, and custom providers, with features like smart routing and automatic failover.

When to use it

•When you need to integrate multiple AI providers into your application
•When you require more control over the routing and failover of AI requests
•When you want to convert between different AI protocols, such as Gemini and OpenAI-compatible API

Ready-to-paste prompt

curl -X POST -H "Content-Type: application/json" -d "{"model": "gpt-3.5-turbo", "prompt": "Write a short story about a character who discovers a hidden world."}" http://localhost:3000/v1/completions
