## Common Patterns

### Pagination

All list endpoints support pagination:

```bash
# Page 1 (first 20 items)
curl "http://localhost:8000/api/v1/notebooks?limit=20&offset=0"

# Page 2 (next 20 items)
curl "http://localhost:8000/api/v1/notebooks?limit=20&offset=20"
```

### Sorting

Use `sort` and `order` parameters:

```bash
# Sort by title ascending
curl "http://localhost:8000/api/v1/notebooks?sort=title&order=asc"

# Sort by updated date descending (newest first)
curl "http://localhost:8000/api/v1/notebooks?sort=updated_at&order=desc"
```
