LowRouter as a Hermes model provider (`--provider lowrouter`, or LowRouter in `hermes model`). The picker shows the 180 `auto/` chat models with tool calling and 64K+ context, plus the user's own `alias/` models, instead of all 719 IDs from /v1/models. Context windows come from LowRouter's catalog instead of Hermes' 256K fallback, and /usage shows the credit balance in euros. LowRouter bills in EUR, so the plugin reports no USD cost and Hermes shows it as unknown. Maintained by LowRouter.

## Good to know before installing

Registers one model provider and nothing else (no tools, hooks, commands or threads). Prompts, tool schemas and LOWROUTER_API_KEY go to https://api.lowrouter.ai/v1 (or the configured model.base_url) through Hermes' client, and LowRouter forwards each request to the host serving the model. The plugin's own requests are GET /v1/models (cached for an hour) and GET /v1/credits on /usage, to the same base URL with the same key, through Hermes' open_credentialed_url. No files read or written, no processes.

From the plugin's catalog listing.

## How to install

1. Install it. Hermes asks for any API keys it needs (this one needs `LOWROUTER_API_KEY`), then asks whether to turn it on.

```bash
hermes plugins install lowrouter
```

2. Said no? Turn it on later:

```bash
hermes plugins enable lowrouter
```

3. Restart Hermes so it loads the plugin.

Some plugins also need a sign-in or settings: see the official page. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide: https://hermes-agent.nousresearch.com/docs/user-guide/features/plugins
