Yandex Search API as a backend for the built-in web_search (provider name yandex), plus a yandex_generative_search tool for grounded answers with cited sources.

## Good to know before installing

Sends web_search queries and yandex_generative_search questions to searchapi.api.cloud.yandex.net, or to the base URL in YANDEX_SEARCH_API_URL if you set one, with your YANDEX_API_KEY and YANDEX_FOLDER_ID read through Hermes; the Search API is a paid Yandex Cloud service billed to the folder that owns the key; no other endpoint, no telemetry, no file or shell access, no background process. Independent community plugin, not affiliated with Yandex.

From the plugin's catalog listing.

## How to install

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

```bash
hermes plugins install yandex
```

2. Said no? Turn it on later:

```bash
hermes plugins enable yandex
```

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
