Endpoint & model
POST to https://openrouter.ai/api/v1/chat/completions with model 'stealth/ox-alpha' and reasoning enabled.
Reasoning & streaming
Set reasoning.effort to low/high/max and stream:true to receive reasoning and content deltas separately.
Structured output
Strict response_format json_schema isn't reliably enforced — use tool calling for structured data.
