CONNECTIVITY / PUBLIC SOURCES
Medical research API directory
44 documented public API endpoints, including live-connected research sources and future integration points. Directory entries do not mean every service has been individually tested or integrated.
Query public clinical and regulatory datasets
28 NLM/openFDA endpoint adapters are available for keyword lookups. Some endpoints may return no matches or errors; no clinical validity or 24/7 availability is implied. Use generic terms, never patient information.
Configured live-query subset: NLM clinical tables, Europe PMC, Crossref, OpenAlex, ClinicalTrials.gov. Open Library supports bibliographic synchronization.
