Wind Direction and Rain question

[renjithpkr]

Hello
I am going to purchase a windy API license. I have a few questions regarding windy direction and precip and ptype.

1. I see that you are able to show the direction in the windy UI. But why is direction not directly available in the API as a parameter?
2. I wanted to get rain details at a partcular location.I gave  the following parameter for getting rain details

I am assuming precip will be positive value and ptype will be 1 for a place where it is raining. but precip is seen as 0 for 10 and 11 in the below array

but ptype for 10 and 11 are 0

I am confused on how I can understand the rain value at surface.
How can I understand how much rain is there at a given location? Kindly help
