Send Chat Completions

curl https://routing.dari.dev/v1/chat/completions \
  -H "Authorization: Bearer $DARI_ROUTING_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "dari/routing",
    "messages": [{"role": "user", "content": "Hello from Dari"}]
  }'

model must be dari/routing, and messages must contain at least one OpenAI-style message. Common optional fields include stream, temperature, max_tokens, tools, tool_choice, response_format, and reasoning_effort. This example uses your organization’s default router at /v1. To address a specific router instead, send the same body to https://routing.dari.dev/{router_id}/chat/completions. The response uses the standard Chat Completions shape and adds dari_routing:

{
  "model": "openai/gpt-5.6-sol",
  "choices": [{"message": {"role": "assistant", "content": "Hello!"}}],
  "dari_routing": {
    "selected_model": "openai/gpt-5.6-sol",
    "reasoning_effort": "medium",
    "reason": "Selected for this request."
  }
}

See the Chat Completions API reference for fields.
