Router API Overview - Dari

Send requests to https://routing.dari.dev/v1 with a Routing API key and model: "dari/routing". The /v1 path uses your organization’s default router, which starts with Dari’s managed model set and requires no setup.

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"}]
  }'

Address a specific router by its rtr_... ID instead of /v1. Both forms accept the same request bodies, and endpoint paths vary by protocol:

Protocol	Default Router	Specific Router
Chat Completions	`/v1/chat/completions`	`/{router_id}/chat/completions`
Responses	`/v1/responses`	`/{router_id}/v1/responses`
Anthropic Messages	`/v1/messages`	`/{router_id}/v1/messages`

Claude Code, Codex, and Pi take base URLs and append their protocol-specific paths, so use the base URL shown in each coding-agent guide.
