@bacnh85/pi-9router

Pi extension for 9router — connect to your 9router AI routing proxy instance.

Install

pi install npm:@bacnh85/pi-9router

Usage

Configure connection

/login-9router

Prompts for:

• Endpoint URL (default: http://localhost:20128/v1)
• API key (required if your 9router has REQUIRE_API_KEY=true)

Once configured, models from 9router appear in Pi's /model picker under the 9router/ provider prefix.

Toggle reasoning/thinking levels

/9router-reasoning

Toggles Pi thinking-level support for 9router models ON/OFF.

When ON, use Shift+Tab, --thinking high, or model suffixes like 9router/...:high to control reasoning_effort sent to 9router.

Check status

/9router-status

Shows connection status, model count, and current configuration.

Environment variables

| Variable | Default | Description | |----------|---------|-------------| | NINE_ROUTER_BASE_URL | — | Overrides saved endpoint URL | | NINE_ROUTER_API_KEY | — | Overrides saved API key | | NINE_ROUTER_ENABLE_REASONING | — | Overrides saved reasoning toggle (true/false) |

How it works

1. On startup, loads config from ~/.pi/agent/9router-config.json and registers the 9router provider
2. Models are fetched dynamically from GET /v1/models on first use
3. Pi's built-in OpenAI completions API handles all streaming and tool calling
4. No built-in providers are overridden — 9router/ models are a separate namespace
