Avoid sending values of 0 where there is no data

[nightsh]

If there is no data for a value, simply send null or nothing. We have ways of treating them in frontend, but 0 is a value and we will display as it is.

i think its not about what value is sent, rather than what we do with it.
if there is zero value we can display different content, for example message "no data"

@zufanka does it make sense, or we could actually have a legit 0 value anywhere? If so, we can also format values of 0 as something like "n/a" or "y u no data" or whatever.

I don't think there are any legit tenders for 0 money :) Or 0 contracts
I would go for "no data" or "data missing" because "NA" means "not applicable" while it is quite applicable, just missing.
