How this service works
Recent research papers on a topic from OpenAlex: title, year, citations, DOI and open-access link, most relevant first.
Output
Returns a list of research papers ranked by relevance, each with title, publication year, citation count, DOI, journal name, open-access status and URL. Also includes metadata such as the topic query, total matches found, data source (OpenAlex), and timestamp. May include a summary or disclaimer field.
Example use cases
Literature review for a new research project
“I'm starting a project on protein folding prediction — can you pull the 10 most relevant papers on that topic from the last two years, sorted by relevance, with their DOIs and citation counts?”
Finding open-access papers for a blog post
“I'm writing about federated learning and need recent papers I can actually read for free — find me up to 8 open-access papers on federated learning published since 2023.”
Academic competitive landscape scan
“What are the most cited recent papers on large language model alignment? Give me the top 15 results from 2022 onward so I can see who the key researchers and venues are.”

Endpoint
GEThttps://research-papers.x402tookit.com/topic-papers?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to discover multiple relevant academic papers on a topic by keyword, especially when you don't already have specific DOIs. It is ideal for literature review, research landscaping, or finding open-access reading material. Prefer this over DOI-specific endpoints when the user wants broad topic coverage rather than metadata for a known paper.
Side effects
- Topic query too vague or short returns low-relevance results
- No papers found for very niche or misspelled topics
- since_year set too recently may return zero results if field lacks recent indexed papers
- n exceeds 15 or is below 1 returns validation error
- OpenAlex API unavailability may cause degraded or empty response indicated by degraded flag
