NCBI SRA Get Download Urls

Overview

Get FTP and cloud storage URLs for downloading FASTQ sequencing data from SRA runs. Returns multiple access methods: NCBI FTP URLs for direct .sra file download, AWS S3 URLs for cloud-based access (faster for large-scale analysis), and NCBI web URLs for browser access. Note: Downloaded .sra files require SRA Toolkit (fastq-dump or fasterq-dump) to convert to standard FASTQ format. Essential for programmatic access to petabytes of public sequencing data. Works with SRR (NCBI), ERR (ENA), and DRR (DDBJ) accessions.
