The NCBI Datasets platform contains the National Center for Biotechnology Information's gene sequence data and metadata, including gene, genome, and taxonomy indexes. It is possible to search using a variety of identifiers, including organism names, assembly, WGS, or BioProject accessions. It is possible to retrieve and download files individually or in large batches. In addition to using the search interface on this website to access the datasets, you may also access the data via command-line tools and an API.
NCBI Datasets is the replacement for NCBI's legacy Assembly and Genome databases.
