How this service works
Search biomedical literature indexed in PubMed, via OpenAlex (CC0): title, authors, journal, date, DOI, PMID, citation count and open-access link, newest first, with optional year filter. Metadata only (no abstracts).
Output
Returns a JSON object containing the original query string, total number of matching records in PubMed, the source label ('PubMed (NCBI/NLM)'), and an array of article objects — each with title, list of authors, journal name, publication date, abstract summary, DOI, PMID, and a direct PubMed URL link.
Example use cases
Drug efficacy literature review
“Find me the top 20 PubMed articles about GLP-1 receptor agonists and weight loss published since 2022, with titles, author names, and summaries.”
Rare disease research discovery
“Search PubMed for peer-reviewed studies on Niemann-Pick disease type C — give me the 15 most recent results including their DOIs and journal names.”
Gene therapy competitive landscape
“Pull the latest 25 PubMed papers on CAR-T cell therapy published after 2020 so I can summarize the current state of the field.”
Technical details
Endpoint
POSThttps://api.vextorium.com/v1/pubmed-search?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to search the authoritative biomedical literature database (PubMed/NCBI) for peer-reviewed scientific articles, with structured metadata including abstracts, DOIs, and author lists. It is ideal for research assistants, medical AI workflows, drug discovery pipelines, or any agent task requiring access to life sciences publications. Prefer this over general web search when the user specifically wants indexed academic journal articles from PubMed rather than broader web content.
Side effects
- Empty or overly broad query returns large result sets that may be truncated
- Very narrow or misspelled queries return zero articles
- since_year filter with future year or invalid integer may return no results
- Rate limits or upstream PubMed API downtime may cause failures
- Limit values exceeding backend caps may be silently clamped
