# Configuration

Routstr is configured primarily through the **Admin Dashboard**. All settings persist in the database and take effect immediately—no restarts required.

For automated deployments, you can optionally pre-configure settings via environment variables.

---

## Initial Setup (.env file)

Before running your node, you should create a `.env` file in the project root. This file is used to bootstrap the initial configuration and store sensitive secrets.

### Example .env

```bash
ADMIN_PASSWORD=your-secure-password

# Node Identity
NAME="My AI Node"
DESCRIPTION="Fast access to models"

# Lightning Payouts
RECEIVE_LN_ADDRESS=yourname@wallet.com
```

### Setting the UI Password

There are two ways to set or change your Admin Dashboard password:

1.  **Via Environment Variable**: Set `ADMIN_PASSWORD` in your `.env` file before starting the container. This will be the password used for the first login.
2.  **Via Dashboard**: Once logged in, go to **Settings** → **Security** to update your password. Dashboard settings override the `.env` file once saved.

---

## Admin Dashboard (Primary)

Access the dashboard at `/admin/` on your node.

### Upstream Providers

Connect to your AI provider(s):

| Setting          | Description                                      |
| ---------------- | ------------------------------------------------ |
| **Upstream URL** | API endpoint (e.g., `https://api.openai.com/v1`) |
| **API Key**      | Your provider's API key                          |

### Node Identity

How your node appears to clients:

| Setting         | Description                            |
| --------------- | -------------------------------------- |
| **Name**        | Display name (e.g., "Fast GPT-4 Node") |
| **Description** | Brief description of your service      |

### Pricing

Control your profit margins:

| Setting           | Description                                | Default      |
| ----------------- | ------------------------------------------ | ------------ |
| **Fixed Pricing** | Charge flat rate per request vs. per-token | Off          |
| **Exchange Fee**  | Buffer for BTC volatility                  | 1.005 (0.5%) |
| **Upstream Fee**  | Your profit markup                         | 1.10 (10%)   |

See [Pricing](pricing.md) for detailed strategies.

### Cashu Mints

Which mints to accept payments from:

| Setting   | Description                     |
| --------- | ------------------------------- |
| **Mints** | List of trusted Cashu mint URLs |

### Lightning Withdrawals

Automatic profit withdrawal:

| Setting                              | Description                                                                                                | Default |
| ------------------------------------ | ---------------------------------------------------------------------------------------------------------- | ------- |
| **Lightning Address**                | Your LN address for withdrawals                                                                            | —       |
| **Minimum Payout (sat)**             | Min available balance (in sats) before profit is paid out. Applies to both `sat` and `msat` mints (auto-converted). | `210`   |
| **Payout Interval (seconds)**        | How often the payout loop wakes up and checks balances                                                     | `900`   |

All payout amounts must be positive. Set the minimums above your wallet's
minimum-invoice constraint (typically 1 sat) and high enough to amortise
routing fees.

### Security

| Setting            | Description                   |
| ------------------ | ----------------------------- |
| **Admin Password** | Password for dashboard access |

### Nostr Discovery

Announce your node on the network:

| Setting    | Description                          |
| ---------- | ------------------------------------ |
| **Npub**   | Your Nostr public key                |
| **Nsec**   | Your Nostr private key (for signing) |
| **Relays** | Relays to publish announcements      |
| **Share Analytics** | Publish aggregate usage stats to Nostr |

See [Discovery](discovery.md) for details.

## Environment Variables (Optional)

Use environment variables for:

- **Automated deployments** (CI/CD, infrastructure-as-code)
- **Secrets management** (external secret stores)
- **Initial bootstrap** (set once, manage via dashboard later)

### Priority

Environment variables are read on startup. Dashboard settings override them and persist in the database. Once you change a setting in the dashboard, the env var is ignored for that setting.

---

## Models

Manage which AI models you offer:

1. Go to **Models** in the dashboard
2. Models are auto-discovered from your upstream
3. For each model, you can:
   - **Enable/Disable** — hide expensive models you don't want to serve
   - **Override pricing** — set custom per-token rates
   - **Create aliases** — friendly names for models

See [Pricing](pricing.md) for per-model pricing strategies.
