description: Ensembl is a genome annotation database and browser maintained by the European Bioinformatics Institute (EMBL-EBI)
  and the Wellcome Sanger Institute. It provides comprehensive genome data for vertebrates and other eukaryotic organisms,
  covering gene annotation, variant data, regulatory features, comparative genomics, and evolutionary analysis across hundreds
  of species. The Ensembl REST API offers language-agnostic HTTP access to this genome data without requiring local database
  installations or Perl API dependencies.

  name: Ensembl REST API
  description: The Ensembl REST API (v15.12) provides language-agnostic HTTP access to genome annotation data across hundreds
    of vertebrate and eukaryotic species. It exposes 19 endpoint categories covering genome sequences, gene and transcript
    lookups, variant effect prediction (VEP), comparative genomics (gene trees, homology, alignments), coordinate mapping
    between assemblies, regulatory features, linkage disequilibrium, ontology and taxonomy queries, phenotype annotations,
    and GA4GH-compliant genomic data access. Both GET and POST methods are available; POST endpoints support batch operations
    for multiple identifiers. No authentication is required for public use.
