I would like to be able to batch download FASTA files from ENSEMBL. I normally would use the API to download them from the ENSEMBL gene IDs. However, the IDs aren't ones I know, only ones I would get from searching on the ENSEMBL website and collecting the IDs manually.
Is there a way I can use the API to query search terms and collect all results that are returned?
So for example, if I use the ENSEMBL website to search "HLA" I could collect the list of IDs (ENSG00000204252 etc. etc.) manually. HLA works okay using the API to query gene IDs because there's only a few terms (A, B, C plus non-classical for class I) but I was wondering if there was a way to directly access the search query one the homepage programmatically, as I may need to do it for some messier examples.
