Data Source

PubMed: NCBI E-utilities API — 37M+ biomedical articles from 5,200+ journals
ClinicalTrials.gov: v2 API — 500K+ clinical studies worldwide

Both APIs are maintained by the U.S. National Institutes of Health. Free, no API key required.

FAQ

Q: Do I need an API key? A: No. Both PubMed and ClinicalTrials.gov APIs are free and open.

Q: How current is the data? A: PubMed indexes new articles within days of publication. ClinicalTrials.gov updates are near real-time as sponsors submit data.

Q: Can I get full-text articles? A: This server provides abstracts and metadata. Full-text access depends on publisher open-access policies.

Q: Is there a rate limit? A: The server handles NCBI's rate limiting (3 req/sec) automatically. No client-side throttling needed.
