Steps your workflow can run in OpenAlex.

Search worksSearch and filter OpenAlex's catalogue of scholarly works: journal articles, preprints, books, datasets, dissertations and more. Search the title, abstract and full text by keyword or by meaning, then narrow by publication date, work type, open-access status, language, author, institution, country, journal, topic, funder, UN Sustainable Development Goal, licence or citation count.

Get a workGet one work in full by its identifier: an OpenAlex id, a DOI, a PubMed id, a PMC id or a Microsoft Academic id. Returns everything OpenAlex holds about it, including the abstract rebuilt into readable text, every author with their affiliations, where free copies live, its topics, the works it cites and its citation counts. Single lookups are free, however many a workflow makes.

List works citing a workList the works that cite a given work - its citations, forwards in time. Use it to see who picked a paper up, to watch for new citations on a schedule, or to build a citation network one hop at a time. Sorts, filters and pages like any other work search.

List works a work citesList the works a given work cites - its bibliography, backwards in time. The mirror of List works citing a work, and the way to pull a paper's reference list as full records rather than bare ids.

Download a work's full textDownload the cached full text of a work as a file, either the original PDF or machine-readable TEI XML. OpenAlex holds full text for more than 50 million works; check the work's has_content field, or filter on has_content.pdf, before asking. The file lands in document storage, so a later step can attach it to an email, put it in a folder or read it.

Search authorsFind researchers by name, ORCID, institution, subject or impact. Returns each profile with its ORCID, current affiliations, topics, works and citation counts and h-index. This is how you turn a person's name into the author id that Search works filters on. Profiles are assembled by matching the names printed on papers, so a common name can produce several candidates - match on ORCID whenever you have one.

Get an authorGet one researcher's profile by OpenAlex id or ORCID: their name and its variants, every affiliation with the years, their topics, how many works they have, how often they are cited, their h-index and i10-index, and citations per year for the last decade. Free.

Search journals and repositoriesFind the places works are published: journals, preprint servers, institutional repositories, conference proceedings and book series. Search by title or ISSN, or filter to build a list - every fully open-access journal listed in DOAJ, every repository in a country, the journals a publisher owns. Each result carries its ISSN, publisher, open-access status, article processing charge and impact statistics.

Get a journal or repositoryGet one source by OpenAlex id or ISSN: its titles and ISSNs, who publishes it, whether it is open access and whether DOAJ lists it, what it charges to publish, the topics it covers, and its works, citations and h-index over time. Free.

Search institutionsFind universities, hospitals, companies, government agencies and other research organizations. Search by name or acronym, or filter by country, continent, kind of organization or size.

Get an institutionGet one organization by OpenAlex id or ROR: its names and acronyms, where it is, what kind of organization it is, the organizations above and below it, its repositories, the topics it publishes on, and its output and citation counts year by year. Free.

Search publishersFind publishing companies and the imprints beneath them, from Elsevier and Springer Nature down to a single university press. Publishers nest: level 0 is a root company and each level below is a division or imprint, so filter by level to compare like with like. Each result carries its countries, its parent, and how many works and citations it accounts for.

Get a publisherGet one publisher by OpenAlex id or ROR: its names, where it sits in the publishing hierarchy, the countries it operates in, its logo, and its works and citation counts over time. Free.

Search fundersFind the organizations that pay for research: national agencies, charities, foundations and corporate funders. Search by name or filter by country. Each result carries its ROR id, how many grants it has made and how many works acknowledge it - the id you then use to filter works or grants by who paid for them.

Get a funderGet one funder by OpenAlex id or ROR: its names, country, homepage and logo, how many grants it has made, and the works and citations that acknowledge it, year by year. Free.

Search grantsSearch more than 17 million research grants: what was funded, by whom, for how much and over what period. Filter by funder, grant number, funding type, recipient institution, country, start year or amount. Where a funder answers who paid, a grant answers which award - so this is the action behind 'what has this agency funded in our field since 2020'.

Get a grantGet one research grant by its OpenAlex id: its title and abstract, the funder and the funder's own grant number, the amount and currency, start and end dates, the principal investigator and co-investigators, the institutions that received it, and the works it paid for. Free.

Search topicsSearch the roughly 4,500 subjects OpenAlex classifies every work into. Topics sit at the bottom of a four-level hierarchy - domain, then field, then subfield, then topic - and each one comes back with its keywords, its place in that hierarchy and how many works carry it. Use this to turn a subject you can describe into the topic id that Search works filters on; filtering by a subject's name never works.

Get a topicGet one topic by its OpenAlex id: what it covers, the keywords associated with it, its subfield, field and domain, its sibling topics, and how many works and citations it accounts for. Free.

Search keywordsSearch the roughly 65,000 short phrases works are tagged with. Keywords are finer-grained than topics - 'type-1 diabetes' rather than 'Diabetes and Metabolic Disease' - so they are the better handle on a narrow slice of the literature. Each comes back with how many works carry it.

Get a keywordGet one keyword by its slug - keywords are named 'machine-learning' rather than by a letter-and-number id. Returns its label, how many works carry it, how often those works are cited, and a ready-made link to them. Free.

Search concepts (legacy)Search concepts, the six-level subject classification OpenAlex used before topics. OpenAlex has deprecated them in favour of topics and no longer maintains them, but they are still attached to every work, so this is the way to reproduce or continue an analysis built on them. For anything new, use Search topics.

Get a concept (legacy)Get one concept by OpenAlex id or Wikidata id: its description, its level, the concepts above and beside it, and its works and citation counts. Deprecated in favour of topics, and kept for continuity with older analyses. Free.

List Sustainable Development GoalsList the United Nations' 17 Sustainable Development Goals as OpenAlex holds them, each with how many works a classifier has tagged to it and how often those works are cited. There are exactly 17, so one call returns them all. This is the vocabulary behind questions like 'how much of our research is about clean water'.

Get a Sustainable Development GoalGet one UN goal by its number, 1 to 17: its name, the one-sentence statement of it, its official icon, and how many works and citations it accounts for. Free.

List subject levelsList the levels of OpenAlex's subject hierarchy above a topic: 4 domains, 26 fields or 252 subfields, whichever you pick. Small enough to browse in one call, and the right handles for grouping a large result set - works per field, authors per domain. Each entry carries its parents, its children and its share of the literature.

Get a domain, field or subfieldGet one level of the subject hierarchy by its number - domain 3, field 17, subfield 1702. Returns its description, the levels above and below it, its siblings, and how many works and citations sit under it. Free.

List a vocabularyList one of OpenAlex's eight fixed value sets: work types, source types, institution types, countries, continents, languages, licences or indexes. These are the exact values filters are written against, each with how many works it covers - what a workflow reads to build a picker, or to check a code before filtering on it.

Get a vocabulary entryGet one entry from a controlled vocabulary by its code: the country US, the language fr, the licence cc-by, the work type preprint. Returns what the value means and how many works it covers, plus a ready-made link to them. Free.

AutocompleteTurn a half-typed name into an OpenAlex id, fast. This is the documented way to resolve a name before filtering by it - OpenAlex matches ids, never names, so 'works by MIT' means looking MIT up first. Each suggestion carries a hint that tells similar names apart: an author's institution, a work's authors, an institution's city.

Check API usageCheck how much of today's OpenAlex budget is left: the daily credit limit, what has been spent, what remains, when it resets, and what each kind of call costs. Worth reading at the top of a scheduled workflow that is about to make thousands of calls. Needs an API key on this connection - the figures are about the key.

Run a query (OQL)Run a query written in OpenAlex Query Language, which reads like a sentence: 'works where year is (2020) and cited_by_count > (100) group by type'. OQL reaches questions the filter fields cannot express - nested boolean logic, proximity search, grouping written into the query itself - and the query names its own entity, so one action covers every kind.

Translate and check a queryTranslate a query between the three ways OpenAlex spells one - readable OQL, a JSON query object, and a classic /works?filter=... URL - and validate it, without running it. An invalid query comes back with the character position and a suggested fix rather than a silent empty result.

List saved collectionsList the saved collections on this connection's OpenAlex account. A collection is a private, named list of entities of one type - the papers you are tracking for a grant, the journals in your library's subscription - and its id drops straight into a filter, so you name a thousand journals once instead of in every request. Needs an API key.

Get a saved collectionGet one saved collection: its name, description, what kind of entity it holds and how many. The entities themselves are paged separately - use List a collection's entities for those. Needs an API key, and the collection has to belong to this connection's account.

List a collection's entitiesList the ids inside a saved collection, up to 200 at a time. Paged separately from the collection itself so a 1,000-entity list does not arrive attached to every read of its name. Needs an API key.

Create a saved collectionCreate a private, named list of OpenAlex entities of one type, holding up to 1,000 of them. Once it exists, its id goes in the 'Saved collection' field of any search on that type, or into an id filter on a related type - a collection of journals filters works by where they were published. A collection holds one type only, so tracking works and their authors means two collections. Needs an API key.

Update a saved collectionRename a saved collection, change its description, or change what kind of entity it holds. Only the fields you fill in change. The entity type can only be changed while the collection is empty. Needs an API key.

Add entities to a collectionAdd entities to a saved collection in one call - the step that turns a search into a saved list. Ids already in the collection are counted rather than duplicated, and an id of the wrong kind is refused outright naming the offender. A collection holds at most 1,000 entities. Needs an API key.

Remove entities from a collectionRemove entities from a saved collection in one call. The entities themselves are untouched; only their membership goes. Needs an API key.

Delete a saved collectionDelete a saved collection and its membership list. The entities in it are untouched - only the list goes, and it cannot be undone. Needs an API key, and the collection has to belong to this connection's account.
