Research Paper Scraper
Pricing
from $0.70 / 1,000 papers
Scholar scrapers fail because Scholar blocks them. OpenAlex is open, keyless and unblockable. Three fields Scholar will not give you: the abstract rebuilt from the inverted index it ships instead of prose, field-weighted impact so citations compare across fields, and 134,038 retraction flags.
type
Optional
work or analysis.
openAlexId
Optional
Short OpenAlex work id, e.g. W2741809807.
doi
Optional
Bare DOI without the resolver prefix.
title
Optional
Paper title.
publicationYear
Optional
Year of publication.
publicationDate
Optional
ISO publication date.
workType
Optional
article, review, preprint, book-chapter, dataset and so on.
isRetracted
Optional
OpenAlex flags the work as retracted. It carries over 134,000 such records; Google Scholar surfaces none of them, and citing one is a real problem.
isParatext
Optional
Front matter, index or editorial furniture rather than research.
citedByCount
Optional
Raw citation count. On its own it is not comparable between fields — see fwci.
fwci
Optional
Field-weighted citation impact. 1.0 is exactly average for this work's field and year, 2.0 is twice the field average. This is what makes citation counts comparable across disciplines, and no other scraper returns it.
citationPercentileMin
Optional
Lower bound of the work's citation percentile within its field and year. 99 means top 1%.
citationPercentileMax
Optional
Upper bound of that percentile band.
referencedWorksCount
Optional
How many works this paper cites.
isOpenAccess
Optional
A legally readable full text exists.
openAccessStatus
Optional
gold, green, hybrid, bronze or closed.
openAccessUrl
Optional
Direct link to the free full text.
sourceName
Optional
Journal, conference or repository.
sourceType
Optional
journal, repository, conference, book series.
sourceIssn
Optional
Linking ISSN of the source.
publisher
Optional
Host organisation behind the source.
primaryTopic
Optional
OpenAlex topic, the most specific classification.
primaryField
Optional
Broader field the topic sits in.
primaryDomain
Optional
Broadest grouping: Physical Sciences, Life Sciences, Health Sciences, Social Sciences.
firstAuthor
Optional
First author.
correspondingAuthors
Optional
Authors marked corresponding — the ones to contact.
institutions
Optional
Distinct author institutions.
institutionRors
Optional
ROR ids for those institutions, for joining to other datasets.
countries
Optional
Distinct country codes across author institutions.
isInternationalCollaboration
Optional
Authors span more than one country.
abstract
Optional
The abstract, rebuilt into prose. OpenAlex is obliged to ship abstracts as an inverted index of {word: [positions]} rather than text, which is unreadable as returned. Reconstructing it is one of the reasons this actor exists.
openAlexUrl
Optional
Canonical OpenAlex URL for the work.
doiUrl
Optional
Resolvable DOI link.
