What is LLMFly AI?
LLMFly AI is a unified API gateway that lets developers call GPT, Claude, Gemini, Grok, and other leading models through a single OpenAI-compatible endpoint. Instead of rebuilding integrations for each provider, you keep your existing OpenAI SDK client and simply change the base URL, API key, and model ID. It offers consolidated pricing across providers, per-app API keys, and usage history so you can see costs before and after sending traffic.
How to use LLMFly AI?
- 1. Create an API key, using a separate key for each app and environment. 2. Point your server-side OpenAI client to the LLMFly AI endpoint by updating the base URL. 3. Copy a model ID from the catalog and start with a short, non-streaming request. You can also copy the integration guide into tools like Claude Code, Codex, or Cursor to automate setup.
