How this service works
Scientific literature search API with x402 micropayments. Search PubMed, arXiv, and Crossref citations.
Output
A list of PubMed article records matching the search query, including titles, authors, publication dates, abstracts, and PubMed IDs, filtered and sorted according to the specified parameters.
Example use cases
Example prompt
“Search PubMed for the top 10 most recent studies on CRISPR gene therapy for sickle cell disease, sorted by publication date.”
Technical details
Endpoint
GEThttps://research.memoryapi.org/x402/research/pubmedWhen to prefer
Choose this endpoint when you need peer-reviewed, NIH-indexed biomedical and clinical literature specifically. Prefer this over arXiv for clinical, pharmaceutical, or life sciences research that requires the PubMed corpus, and over OpenAlex when you need PubMed-specific indexing, MeSH terms, or NIH-sourced metadata.
Side effects
- Empty query returns no results or an error
- Query too vague returns irrelevant results
- Invalid sort order parameter causes request failure
- Rate limiting or payment failure results in 402 error
- PubMed API downtime causes upstream failure
- Limit set too high may be rejected or throttled
