AIGate API

OpenAI-compatible API for text, embeddings, image generation, and supported provider routes.

AIGate gives you one API key and one OpenAI-compatible base URL for the models enabled in your account. The same key works for chat, Responses, Anthropic Messages, embeddings, and image generation routes.
