Example code & API

Call OpenAI-compatible routes below. Replace the model field with this model’s routing code and paste an API key from the console into the Authorization header.

Traffic is proxied through the unified gateway; each model type maps to a different endpoint (chat, embeddings, images, rerank, speech, etc.), and the snippets switch automatically for the current type.

In production, set sensible timeouts and retries, and keep request identifiers from responses for debugging.
