Query TCGA projects for variant presence


I have a set of variants of which i want to know whether they are present is a set of (or even all) TCGA studies using an api or downloading files for a local query. It would also be helpful to get the cancer type associated with the found variant. Also the variants are only small indels & snps.
The GDC website provides the exact function required for my project, but from what I can tell this is not possible using their api. I have already been searching for a while, since there are multiple ways to access TGCA data. But the cBioPortal api does neither get it done, nor am I 'authorised' to download any .vcf files from the GDC Legacy archive
I really hope someone has an idea help me!
