How this service works
Academic paper search across 250M+ works (OpenAlex): title, authors, year, venue, DOI, open-access PDF link, citation count and abstract. Sort by relevance, most recent or most cited.
Output
A list of up to 25 academic paper records, each containing: title, list of authors, publication year, venue/journal name, DOI, open-access PDF URL (if available), citation count, and abstract. Results are sorted by relevance, recency, or citation count depending on the sort parameter.
Example use cases
Literature review on a research topic
“Find me the 15 most cited academic papers on CRISPR gene editing since 2015 — I need the titles, authors, venues, and abstracts to build a literature review.”
Discovering recent open-access papers
“Search for the most recent papers on large language model alignment published in 2024, sorted by recency, and tell me which ones have open-access PDFs I can actually download.”
Background research for a specific claim
“Look up academic papers about the link between sleep deprivation and cardiovascular disease — give me up to 20 results sorted by citation count so I can find the landmark studies.”
Technical details
Endpoint
GEThttps://agentrxi.com/v1/papers?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured metadata for academic and scientific papers at scale (250M+ works), especially when you need citation counts, DOIs, or open-access PDF links. It is preferable to general web search for literature review tasks, since it returns structured bibliographic data directly from OpenAlex rather than HTML snippets. Prefer it over PubMed-specific APIs when you need cross-disciplinary coverage beyond biomedical literature.
Side effects
- Query string missing — returns 400 error
- Limit out of range (must be 1–25) — returns validation error
- No papers found for niche or misspelled query — returns empty results list
- OpenAlex upstream unavailability — returns 502 or timeout
- Payment failure (x402) — returns 402 Payment Required before any data is returned
