Quickly get allele frequencies from Gnomad

Question

[Floydian_slip]

Hi, I would like to know the AF of ~4000 rsIDs (dbSNP) quickly in Gnomad GRCh37 database. I looked at the instructions for getting this from Gnomad and it seems I would need to download the entire data. Is there is a faster and less involved way fo getting the AF from Gnomad without downloading more than 50GB of data? Any script or API or another way to crawl Gnomad database? Thanks!

The af-only-gnomad.raw.vcf file here is 13 GB. It might work better than the 80+ GB file from the gnomAD website.

I created a python package based on SQLite databases, where you can easily query all gnomAD variants for GRCh37/38. https://github.com/KalinNonchev/gnomAD_DB
I have precomputed SQLite databases for gnomAD WGS for GRCh37/38 in the description of the package. Please take a look there.

Best,
