Chat completion (any provider) | Enterprise Router

Send an OpenAI-compatible request and Enterprise Router routes it to the right provider. Use provider/model format (e.g. openai/gpt-4o, anthropic/claude-sonnet-4-6, google/gemini-2.5-flash) or a plain model name for well-known models. Set stream: true for server-sent event streaming.
