"""
NeuralBridge Adapter for Notion.

This adapter provides a bridge to the Notion API, allowing for interaction
with Notion databases and pages. It supports querying databases, creating and
updating pages, and searching for content within a Notion workspace.

**Configuration:**

The adapter is configured via a YAML file, which should include the following
keys:

```yaml
adapter: notion
config:
  api_key: "YOUR_NOTION_API_KEY"
  workspace_id: "YOUR_NOTION_WORKSPACE_ID"
  default_database_id: "YOUR_DEFAULT_DATABASE_ID"
```

**Supported Operations:**

- `query_database`: Queries a Notion database with optional filters and sorts.
- `create_page`: Creates a new page in a specified database or as a child of another page.
- `update_page`: Updates the properties of an existing Notion page.
- `search`: Searches for pages and databases in the workspace.
- `get_page`: Retrieves a single page by its ID.
- `list_databases`: Lists all databases accessible to the integration.
