SiteCheck Web Intel – Europe PMC Literature Search

Choose this endpoint when you need bibliographic metadata (title, authors, journal, year, DOI, citation count) for life-science papers including preprints from Europe PMC, and do not require full abstracts or full text. Prefer this over PubMed PMID lookup when you need keyword or query-based discovery rather than a single known PMID; prefer it over general web search when you need structured, citable academic metadata in a biomedical context.

• Query string missing or empty — returns error requiring the 'q' parameter
• Query exceeds 200 characters — rejected with validation error
• Limit outside 1–25 range — may return default count or error
• No matching articles found — returns empty results list
• Europe PMC upstream API unavailable — returns gateway or timeout error
• Malformed query syntax — may return zero results or unexpected matches
