There is no built-in reader for parsing header files. You can perform simple text processing as follows to get either name/value data set, or single row table after transposing.
Example:
filename header temp;
* simulate header returned from API GET call;
data _null_;
file header; input; put _infile_; datalines;

_cpos = index(_infile_,':');
name = substr(_infile_,1,_cpos-1);
value = substr(_infile_,_cpos+1);

proc transpose data=header_items out=header_vars(drop=_name_);
id name;
var value;
run;
Name Value pairs
Header attribute name as column name (after transpose)
