Ensembl Get Assembly Info

Get genome assembly metadata for a species from the Ensembl REST API. Returns assembly name, accession, version history, chromosome karyotype with sizes, genebuild date, golden path length, and available coordinate system versions. Essential for interpreting genomic coordinates and understanding assembly composition. Example: 'homo_sapiens' returns GRCh38.p14, assembly date 2013-12, genebuild May 2025, 194 top-level regions, karyotype chromosomes 1-22 plus X and Y.
