DatePicker (machine?) api is not documented

[dannylin108]

I want to customize a look of DatePicker's TableBody, but can't find documentation of api parameter?

Here's my SolidJS snippet:

<DatePicker.TableBody>
      {api().weeks.map((week, id) => (
          <DatePicker.TableRow key={id}>
              {week.map((day, id) => (
                  <DatePicker.TableCell key={id} value={day}>
                      <DatePicker.TableCellTrigger asChild>
                          <IconButton variant="ghost">{day.day}</IconButton>
                      </DatePicker.TableCellTrigger>
                  </DatePicker.TableCell>
              ))}
          </DatePicker.TableRow>
      ))}
  </DatePicker.TableBody>

So what methods and properties that api() is exposing? The link to zag.js where it maybe supposed to be documented is also broken: https://zagjs.com/components/solid/date-picker
