I found out the only way to get genotype frequency programmatically from 1000 genomes is via the Perl API as per this answer: Genotype Frequency from Ensembl BiomaRt

Following the instructions here: http://asia.ensembl.org/info/docs/api/variation/variation_tutorial.html?redirect=no, I can see how to get specific genotypes for all individuals as a list:

Is there a way through the Perl API that I can get the actual population genotype frequency as a single returned value for a specific SNP?

E.g., Input -> Some snp, CEU... Output -> G/G 0.87, G/A 0.13 (frequency of some snp for CEU population).

I need to do this for 100,000+ SNPs, so I imagine manually pulling all genotypes for each SNP and calculating the frequency manually in a loop would not be practical.

Just a simple example command or link to where this is shown would be perfect.
