Importing CSV into QGIS with Python, Specific Parameters?

Question

I would like to know where I can find a list of parameters that can be specified when importing a CSV into QGIS using python. The documentation I've found only shows a few options.

QGIS Cookbook

I would like to specify the number of lines to skip, and the fields of the X and Y when there isn't a header. How do I find the complete list of options?

Here are the parameters required while importing a delimited text file: (String values are usually case-insensitive. Yes, yes, YES are all valid)

key	value(s)
crs	e.g. epsg:4326, EPSG:3857
type	csv/regexp/whitespace
delimiter	<delimiter character(s) or regular expression>
xField	<field name>
yField	<field name>
zField	<field name>
mField	<field name>
spatialIndex	yes/no/y/n
subsetIndex	yes/no/y/n
watchFile	yes/no/y/n
geomType	none/point/line/polygon
wktField	<wkt field name>
maxFields	number
quote	<quote character> e.g. "
escape	<escape character> e.g. "
skipLines	number
skipEmptyFields	yes/no/y/n
useHeader	yes/no/y/n
xyDms	yes/no/y/n
trimFields	yes/no/y/n
encoding	<encode> e.g. utf-8, turkish, latin1

Uri structure:
