Literature Reviews and R&D Intelligence at Scale with the OpenAlex Scraper

OpenAlex is the open index of the world’s research — over 250 million papers, with authors, institutions, venues and citation networks. It’s the free successor to Microsoft Academic Graph, and it turns literature review and R&D intelligence from a manual slog into a query. This guide shows how.

TL;DR: Use the OpenAlex Scholarly Works Scraper to pull papers filtered by topic, year, citation count, open-access status and type — flattened to one clean record per work with authors, institutions, venue, citations and reconstructed abstracts. Run a literature review, map a research field, or scout talent. No API key, zero charge on empty runs, first 25 works free.

Why a structured feed beats manual search

A literature review or competitive R&D scan means assembling a filtered, citation-ranked corpus on a topic — then reading the abstracts. Doing that by hand across hundreds of papers is the slow part. The scraper returns them already structured: title, DOI, year, type, authors, institutions, venue, citation count, open-access status, top concepts and (on request) the reconstructed abstract.

Run a literature review

Pull the most-cited recent work on a topic, with abstracts:

{
  "searchTerm": "perovskite solar cells",
  "fromYear": 2022,
  "minCitations": 25,
  "includeAbstract": true,
  "maxResults": 300
}

Results come back most-cited first, so the field’s anchor papers are at the top. Feed the abstracts to an LLM to cluster themes, summarize the state of the art, or draft the related-work section — grounded in real papers with DOIs.

Map a research field or institution

Drop the citation floor and group the results by author_institutions or concepts and you have a map of who is publishing on a technology, where, and how the work connects. That’s the raw material for R&D landscaping, partner scouting, and talent identification.

Track open access and trends

Filter openAccessOnly to build a corpus you can actually read in full, or set a year range and count works per year to quantify whether a field is heating up or cooling down — a defensible, sourced trend line in one run.

Pricing and reliability

The OpenAlex Scholarly Works Scraper is pay-per-result: first 25 works free on every account, then $0.002 per work. Searches that return nothing are never charged. No API key — OpenAlex is fully open, and the actor joins its fast “polite pool” for speed.

FAQ

Do I need an API key? No. OpenAlex is fully open; the actor uses its fast polite pool.

How many works are indexed? Over 250 million, across every field of research.

Can I get abstracts? Yes — turn on includeAbstract and the actor reconstructs readable abstract text from OpenAlex’s inverted index.

How do I get the most-cited papers? Just set searchTerm (and optionally minCitations); results are returned most-cited first.

Can I filter to open-access only? Yes — set openAccessOnly to build a corpus you can read in full.
