description: >-
  The UCSC Genome Browser is a widely-used bioinformatics tool providing access to genomic
  data, sequence information, and annotation tracks for hundreds of organisms. The REST API
  provides programmatic access to genome assemblies, DNA sequences, annotation tracks, and
  track hubs. No authentication is required; rate limiting of one request per second is
  recommended. Data is returned in JSON format.
