Exac describes a REST API here: http://exac.hms.harvard.edu .
Among the supported requests, are those with prefix /rest/variant
and those with prefix /rest/variant/variant
.
I can see from the examples given in that page that these two requests produce different results when given the same argument, but I don't know how to interpret this difference.
Which of the two forms is the one I should use to obtain the minor allele frequency for a variant?
