How this service works
Searches PubMed and returns citation metadata for each hit: title, journal, publication date, authors, DOI and PMID.
Output
Returns a list of citation records for each PubMed hit, where each record includes the article title, journal name, publication date, list of authors, DOI, and PMID. The number of results is controlled by the limit parameter (1–50, default 10).
Example use cases
Literature review for a research topic
“Search PubMed for the 10 most relevant articles on mRNA vaccine immunogenicity and give me the title, journal, authors, and DOI for each one.”
Finding recent clinical trial papers
“Look up PubMed for papers on metformin and type 2 diabetes published most recently — show me the top 5 results sorted by pub_date with their PMIDs and DOIs.”
Collecting citations for a grant proposal
“Search PubMed for 'Alzheimer's disease AND amyloid beta AND immunotherapy' and return the first 20 citations including titles, authors, journals, and DOIs so I can build my reference list.”
Technical details
Endpoint
GEThttps://fittings.sh/v1/pubmed/citation-searchWhen to prefer
Choose this endpoint when you need structured citation metadata from PubMed — including DOIs, PMIDs, authors, and journal info — for a natural-language or Boolean query. It is ideal for automating literature reviews, building reference lists, or enriching data pipelines with biomedical citations without needing a full PubMed API key or complex NCBI integration.
Side effects
- Empty result set if the query term matches no PubMed records
- Invalid or malformed query term causing a bad request error
- Limit value outside the 1–50 range causing a validation error
- PubMed API downtime causing upstream errors
- Rate limiting or payment failure for x402 transactions
