Use Bio.Entrez to access NCBI databases (e.g., PubMed/GenBank) for searching, fetching summaries, and downloading records when your workflow needs to call the NCBI E-utilities API over the network.

When to use

• You need to search PubMed for articles by keyword, author, journal, or date range and then retrieve metadata or abstracts.
• You want to download GenBank records (e.g., nucleotide/protein sequences) in batch given accession IDs or search queries.
• You need to convert identifiers or discover related records across NCBI databases (e.g., PubMed ↔ PMC, Gene ↔ Protein) via cross-links.
• You must retrieve lightweight summaries (titles, IDs, basic metadata) before deciding which full records to fetch.
• You are integrating NCBI E-utilities into an automated pipeline and need API key usage and rate-limit-aware requests.
