PubMed E-utilities (NCBI Entrez)
Search and fetch 35M+ biomedical citations and abstracts, no key required
NCBI's Entrez Programming Utilities (E-utilities) provide programmatic search and retrieval across PubMed and dozens of other NCBI databases (PMC, Gene, Nucleotide, etc.). ESearch returns matching IDs for a query; EFetch/ESummary return the records. Works without a key; a free key raises the rate limit.
