AUTH NONECORS ✓AGENT ✓HTTPS ✓COMMERCIAL ?

The US National Library of Medicine serves its MedlinePlus Genetics articles — conditions, genes, chromosomes, and mtDNA — as downloadable JSON files, one per topic. Fetch a condition by name and you get its summary, synonyms, and linked resources. Heads up: the CORS header only allows *.nlm.nih.gov origins.
