How this service works
PubMed search (NCBI E-utilities): matching articles with PMID, title, authors, journal, publication date and DOI. Citation metadata only, no abstract text. Up to 20 results.
Output
A JSON object containing the search query, total number of matching PubMed records, the source URL (pubmed.ncbi.nlm.nih.gov), a timestamp, and an array of up to 20 results each with PMID, DOI, article title, list of authors, journal name, and publication date.
Example use cases
Evidence lookup for a clinical question
“Find me the latest PubMed studies on metformin and type 2 diabetes outcomes — I need the top 5 results with titles, authors, journals, and publication dates.”
Drug safety literature review
“Search PubMed for research on SSRI use during pregnancy and neonatal outcomes, and pull back up to 10 results with their DOIs and journal names.”
Background research on a disease mechanism
“Pull up PubMed abstracts on CRISPR gene editing for sickle cell disease — give me 8 results including authors and publication dates.”
Technical details
Endpoint
GEThttps://api.healthtravel-api.workers.dev/api/health/pubmed-abstracts?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, citation-level biomedical literature metadata from PubMed without requiring a signup, API key, or institutional access. It is ideal for agents that need to surface peer-reviewed evidence for health, drug, or clinical questions on a pay-per-call basis. Prefer it over general web search when you specifically need PubMed-indexed journal metadata (DOI, PMID, authors, journal).
Side effects
- Query string shorter than 2 or longer than 200 characters returns a validation error
- max parameter outside 1–20 range returns an error
- PubMed API unavailability causes upstream failure
- Very broad queries may return low-relevance results
- No results found for highly specific or misspelled queries
