Hi,
Thank you for your comments.
I understand that entire process of FUMA actually takes long if you are only interested in a sew locus.
Unfortunately, we currently do not have solid plan of API due to large amount of pre-procesed data that FUMA requires, however, since this is not the first time to get question about API, we will consider developing API.
As a temporal solution, by uploading a subset of SNPs that you want to annotate not the full GWAS results, this can shorten the process time but the MAGMA results won't be informative in this case.
Best,
Kyoko
