How this service works
Searches PubMed for biomedical literature by free-text query, with optional date range and sort (relevance / pub_date / first_author). Returns total hit count plus PMID, title, authors, journal, publication date, abstract, MeSH terms, and DOI per paper. Federal public-domain data via NCBI. Use it as a medical journal lookup, NIH paper search, clinical-research finder, MeSH-term query, or NCBI E-utilities wrapper.
Output
Returns a total hit count for the query plus a list of matching papers, each containing PMID, title, author list, journal name, publication date, full abstract, MeSH terms, and DOI. Data is sourced from NCBI's public-domain federal database.
Example use cases
Clinical evidence review for treatment decision
“Search PubMed for randomized controlled trials on metformin versus SGLT2 inhibitors for type 2 diabetes published in the last three years, sorted by publication date, and summarize the abstracts and MeSH terms.”
Literature survey for a research paper
“I'm writing a review on neuroinflammation in Alzheimer's disease — can you search PubMed for the most relevant papers from 2018 to 2024 sorted by relevance, and pull back titles, authors, journals, and abstracts?”
Finding papers for a specific first author
“Look up recent PubMed publications by Jennifer Doudna on base editing, sorted by first author, and return the PMIDs, titles, DOIs, and publication dates.”

Endpoint
POSThttps://x402.agentutility.ai/pubmed-search?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs structured, citation-quality biomedical literature data — including abstracts, MeSH terms, and DOIs — directly from the authoritative NIH PubMed database. Prefer it over general web search for medical/clinical queries because results are peer-reviewed, structured, and include rich metadata. Ideal for literature reviews, evidence synthesis, clinical research lookups, and any task requiring NCBI E-utilities data without managing API keys directly. The $0.01 per-call USDC pricing via x402 makes it accessible for autonomous agents.
Side effects
- Query returns zero results if search terms are too specific or misspelled
- Date range filters may exclude relevant preprints or ahead-of-print articles
- Some older papers may lack DOIs or MeSH term annotations
- Rate or usage limits may apply under high query volume
- Abstract may be absent for some older or retracted articles
