How this service works
PubMed search / biomedical literature search / medical journal lookup / NIH paper search / clinical-research finder / MeSH-term query / NCBI E-utilities wrapper. Searches PubMed for biomedical articles 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 via NCBI E-utilities — no API key required.
Output
Returns the total number of matching records plus a list of articles each containing: PMID, title, author list, journal name, publication date, full abstract, MeSH terms, and DOI. Results are paginated/limited by the requested count and sorted by the chosen sort field.
Example use cases
Example prompt
“Search PubMed for the top 10 most relevant papers on CRISPR gene editing for sickle cell disease published between 2020 and 2024, sorted by relevance, and give me the titles, authors, abstracts, and DOIs.”
Technical details
Endpoint
POSThttps://x402-deployer.x402-deployer.workers.dev/pubmed-searchWhen to prefer
Choose this endpoint when you need structured biomedical literature data from PubMed/NCBI including abstracts, MeSH terms, and DOIs — especially when you want date-filtered or relevance-sorted results without managing an NCBI API key. Prefer over raw NCBI calls for its simplified POST interface and x402 micropayment integration.
Side effects
- Query too broad returns very high hit count with low precision results
- Date range yields no results if no papers exist in that window
- Malformed or empty query string returns an error or zero results
- NCBI E-utilities rate limit hit if called at high frequency without delay
- DOI or MeSH terms may be absent for older or preprint-indexed records
