# Custom Section Builder API
The Custom Section Builder allows users to create personalized dashboard sections by defining filter rules or manually selecting books.
## Preview Collection

**Endpoint:** `POST /api/collections/preview`
**Request Body:**
```json
{
"library_id": "uuid",
"rules": [
{
"id": "rule1",
"field": "genre",
"operator": "equals",
"value": "Sci-Fi",
"priority": 1
}
],
"manual_book_ids": ["uuid1", "uuid2"],
"limit": 20
}
```
**Available Filter Fields:**
| Field | Type | Operators |
|-------|------|-----------|
| `title` | text | contains, equals, starts_with, ends_with, regex |
| `author` | text | contains, equals |
| `genre` | select | equals, not_equals, in, not_in |
