UCSC Genomic Data

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.
