NCBI E-utilities is a free public API with no proxy or scraping costs, giving this Actor margins above 95%.

Limitations

• Abstract fetching requires additional API calls and is slower
• NCBI rate limits: ~3 requests/second without an API key
• Very large result sets (>1000) require multiple search strategies
• Some older articles may have incomplete metadata

FAQ

Q: Do I need an NCBI API key? A: No. This Actor works with the public E-utilities API. An API key increases rate limits but is not required.

Q: Can I search by author or journal? A: Yes. Use PubMed search syntax in searchQuery, e.g., Smith J[Author] AND Nature[Journal].

Q: Why are some abstracts empty? A: Not all PubMed records include abstracts. Enable includeAbstract to attempt fetching them.
