Vynex API — One OpenAI-compatible endpoint for GPT, Claude & Gemini

Vynex API

Vynex API is a unified LLM gateway that exposes a single OpenAI-compatible<br>endpoint (https://llm-api.vynexcloud.com/v1). Developers keep their existing<br>OpenAI SDK, set the base_url to https://llm-api.vynexcloud.com/v1, and call<br>GPT-5.x, Claude 4.x, Gemini 3.x, DeepSeek, Qwen and GLM by changing the model<br>field. Streaming and function/tool calling are supported, with transparent<br>per-token pricing.
