GET /uniprotkb/stream

Stream UniProtKB entries in bulk for large dataset downloads. Unlike the search endpoint which returns paginated results, this endpoint streams all matching entries as a continuous response, making it ideal for downloading complete datasets or very large result sets. Use this endpoint when you need to export thousands or millions of entries (e.g., "all reviewed human proteins"). The response is streamed, so you can process entries as they arrive without waiting for the complete dataset. Supports multiple output formats including JSON, TSV, FASTA (for sequences), and compressed output.
