I asked a similar question before but couldn't achieve the desired solution, so I'll try to be more specific this time.
I managed to use Ensembl's API to get the sequences but in two steps that require calling the API twice for every genes' symbols list: one call to
from which response I get the genes' IDs, and another to
to get the sequences for every ID.
I'm looking for a way to do this in a single call (hoping that it's possible). It can be in Linux or in a programming language code (I'm using python).
The answer I was given for my first question was
"You need to use the lookup/symbol endpoint in the Ensembl REST API with the sequence/id endpoint."
I'm not sure I understand it and couldn't get the author's clarification, so eventually I decided to try to get some more answers.
