    <p>Hi Ramiro</p>
    <p>Correct: the archive/id endpoint doesn't know how to retrieve the
      history of gene-tree and family IDs</p>

        <div>So, although all entities are the ones listed in e.g.,¬†<a

          the ones that are retrievable via the endpoint "GET
          archive/id/:id" are only: gene, transcript, protein and exon.
          Correct?</div>
        <div><br>
        </div>
        <div>For example, if I try to get a gene tree, e.g.

          Ensembl ID and stable id are the same id. We will have a look

          The list of entities is correct in the FAQ and <a

          refers to the stable ids and versioning of genes, transcripts,
          proteins and exons, this is why they do not have all the
