Am I missing something? The rest API does not seem to support quantity discounts? It can only return the retail price for an item?
Looks like you are right

Qty discounts are not suuported
That is quite disappointing. Seems like a pretty core functionality to me.
app/Tygh/Api/Entities/Products.php
Please replace:
$data = fn_get_product_data($id, $this->auth, $lang_code, '', true, true, true, false, false, false, false);
with
$data = fn_get_product_data($id, $this->auth, $lang_code, '', true, true, true, true, false, false, false);
In this case qty discounts should be returned if info about one product is requested
