OpenAlex Scraper - 250M+ Papers, Abstracts & Citations

Search OpenAlex by keyword and get one row per paper with the abstract as readable text: the title, the authors and their institutions, the year, the citation count, the DOI, whether it is open access and where to read it for free.

The abstract is the part that takes work. OpenAlex does not store abstracts as text. It stores a word-position index, and this actor rebuilds the sentences from it. A paper with no index has no abstract, and the field is null rather than a guess.

Input	Search keywords, with an optional OpenAlex filter
Output	One row per work: title, abstract, authors, institutions, year and date, type, venue, citations, topics, DOI, open-access link
Ceiling	50 works per run without an OpenAlex API key, since OpenAlex serves only a search's first 50 works to callers without one: a bigger ask gets those 50 and a free note saying so. With your own free key, up to 10,000
Account needed	None. Your own OpenAlex API key is optional, for more than 50 works
Price	$2.00 per 1,000 works on the Free plan, a little less on paid plans. The free plan's $5 a month covers about 2,500

🔍 What OpenAlex Scraper does

Your keywords go against OpenAlex's own search, which reads titles, abstracts and full text where it has them. The run returns the first 50 matches in the order you pick, or fewer if you ask for fewer. Give it your own OpenAlex API key and it keeps going, up to 10,000.

You can order by relevance, by citation count or by date, and set a published-on-or-after floor. For anything more specific there is a raw filter field that goes straight through to OpenAlex, so type:article,is_oa:true works exactly as their documentation describes it.

Nothing is written to your dataset until the whole set has been collected, so you get either the full result set or a diagnostic row explaining why not.

▶️ How to scrape OpenAlex papers

1. Open OpenAlex Scraper and click Try for free.
2. Type your keywords into Search query.
3. Set Max works. Start around 50 to see the row shape.
4. Pick a Sort by, add a From publication date if you want, then click Start.
5. Download the dataset as JSON, CSV or Excel, or read it from the Apify API.

💰 How much does it cost to scrape OpenAlex?

$2.00 per 1,000 works on the Free plan. Paid plans pay a little less: $1.98 on Starter, $1.96 on Scale and $1.94 on Business. On the free plan, the $5 Apify gives you each month covers about 2,500 works.

You pay per work delivered. Works that appear twice across pages are dropped before they are counted, diagnostic rows are not charged, and a search that matches nothing is not charged. Set a maximum cost on the run and it stops when it gets there.

📥 What you give it

{
  "query": "protein folding",
  "sort": "citations",
  "fromDate": "2020-01-01",
  "maxItems": 50
}

Field	Default	What it is
query	none, the form starts with machine learning	The keywords to search for. Required.
fromDate	none	YYYY-MM-DD. Only works published on or after this date.
sort	relevance	relevance, citations for most cited, or date for newest first.
filter	none	An OpenAlex filter string, passed through untouched. Comma-separated key:value pairs such as type:article,is_oa:true.
maxItems	100	How many works to return, up to 10,000. Without an apiKey a run returns 50 at most.
apiKey	none	Optional. Your own free OpenAlex API key, kept secret. It lifts the 50-work limit.
notionConnector	none	Optional. Writes each work into your Notion once the run finishes.
notionParentId	none	Optional. The Notion data source to write into.
proxyConfiguration	off	Optional network settings. Off by default, and a normal run does not need it.

filter is handed to OpenAlex as you typed it. A key or value OpenAlex cannot read comes back as a free BAD_INPUT row with OpenAlex's own explanation in details, so a typo does not pass for a search that matched nothing.

If your filter already contains from_publication_date, the fromDate field is ignored. Set the date in one place, not both.

📤 What you get back

A real row from a run on 2 October 2026, with the lists and the abstract cut short (the row carries 19 authors and 10 institutions):

{
  "ok": true,
  "openalexId": "https://openalex.org/W2101234009",
  "doi": "https://doi.org/10.48550/arxiv.1201.0490",
  "title": "Scikit-learn: Machine Learning in Python",
  "authors": ["Fabián Pedregosa", "Gaël Varoquaux", "Alexandre Gramfort", "Michel, Vincent", "..."],
  "institutions": ["Commissariat à l'Énergie Atomique et aux Énergies Alternatives", "..."],
  "year": 2012,
  "publicationDate": "2012-01-02",
  "type": "article",
  "venue": "ORBi (University of Liège)",
  "citations": 63573,
  "concepts": ["Python (programming language)", "Documentation", "Computer science", "MIT License", "Artificial intelligence"],
  "isOpenAccess": true,
  "oaUrl": "https://orbi.uliege.be/handle/2268/225787",
  "abstract": "Scikit-learn is a Python module integrating a wide range of ... machine learning algorithms for medium-scale supervised and unsupervised problems. ...",
  "url": "https://openalex.org/W2101234009"
}

Field	How to read it
openalexId	OpenAlex's permanent id. Use it as your key, since not every work has a DOI.
abstract	Rebuilt from OpenAlex's word-position index. null where there is no index to rebuild from.
authors	Names as OpenAlex holds them, so a few arrive family name first, like Michel, Vincent.
venue	OpenAlex's primary location for the work. Often the journal, but it can be a repository, as above, or null.
citations	OpenAlex's cited-by count, and 0 when OpenAlex has no figure at all.
institutions	The affiliations OpenAlex resolved for the authors, without repeats. Sometimes messy, because the matching is theirs.
concepts	Up to five of OpenAlex's own topic tags, not keywords the authors chose.
isOpenAccess, oaUrl	Whether a free copy is known, and where it is. oaUrl is null when none is known.
type	article, preprint, book-chapter, dataset and so on, in OpenAlex's vocabulary.

🧾 Reading the output

Two kinds of row land in your dataset, and ok tells them apart.

Row	How to spot it	Billed
A work	ok: true and an openalexId	yes
A diagnostic	ok: false and an errorCode	no

The overview table in the Apify Console shows the work columns only, so a diagnostic row looks blank there. Switch to the JSON or All fields view to read it.

Code	What it means
BAD_INPUT	No query was given, OpenAlex could not read the filter or the from-date, or it did not accept your API key. details has OpenAlex's reason.
NO_RESULTS	The request worked and nothing came back.
RATE_LIMITED	OpenAlex asked for a slower pace than the run could keep. Try a smaller run.
SERVER_ERROR	OpenAlex answered with a server error. Usually passes.
NOT_SERVED	This request was not served this run. Re-run it later. Runs before 13 October 2026 wrote BLOCKED here, and runs from 13 to 17 October wrote NETWORK.
NETWORK	OpenAlex was unreachable. Re-run it.
TIME_LIMIT	The run got close to its time limit and stopped on its own. The works delivered before that are complete and charged. Give the run more time, or ask for fewer works, to get the rest.
PARTIAL	OpenAlex stopped serving the search before the run had what you asked for. The works before this row are complete and charged. worksDelivered says how many came back and count how many match.

A run that ends on one of these rows still finishes as succeeded, including when the time limit stopped it before any work came back: the TIME_LIMIT row and an amber status message say so.

💡 What people use it for

• Pulling a field's most-cited work with the abstracts attached, in one file, for a reading list.
• Feeding titles and abstracts to a model that has to summarise research it was not trained on.
• Finding which institutions keep appearing on a topic, using the institutions field.
• Filtering to open access with is_oa:true, so every row has somewhere to read it for free.
• Watching a topic on a schedule with sort on date, so each run surfaces what is new.

🚧 What it does not do

• Keyword search over works only. No author, institution or funder lookup by entity.
• No full text. You get the abstract and a link, not the paper.
• Abstracts are missing where OpenAlex has no index for them, and that is common on older and paywalled records.
• citations cannot tell you zero from unknown. Both read 0.
• No more than 50 works per search without a key. Ask for 500 and you get the first 50 in your sort order, plus a free PARTIAL row. Your own OpenAlex API key lifts that.
• No end date field. Use the raw filter if you need an upper bound.
• Institutions and concepts are OpenAlex's matching, and it is not perfect. Treat them as hints, not as ground truth.
• All or nothing. A failure partway through discards what had been collected, so you get a diagnostic row rather than a partial set.
• It is not an official OpenAlex tool. Dami's Studio is independent and is not affiliated with or endorsed by OpenAlex, or by any other company named on this page.

❓ Questions people ask

Do I need an OpenAlex account or an API key?

Not for the first 50 works of a search. For more, get a free key from your account settings on openalex.org and paste it into OpenAlex API key. It goes only to OpenAlex, stays out of your dataset and log, and the price per work is the same.

Why is the abstract null on some papers?

OpenAlex only keeps a word-position index for a work if the publisher made one available. No index, no abstract to rebuild.

Why is the venue a repository instead of a journal?

OpenAlex picks one primary location per work, and for a paper with a preprint or a repository copy it sometimes picks that. The DOI still points at the published version.

Can I search by author or institution?

Not as a mode. You can approximate it through the raw filter field, using OpenAlex's own filter keys.

Can I call it from code or connect it to an AI assistant?

The API tab has code for Python, JavaScript and the CLI. MCP clients like Claude and ChatGPT use https://mcp.apify.com/?tools=fetch-actor-details,dami_studio/openalex-scraper; coding assistants can load our skill file. All three bill your Apify account at the same price.

Is scraping OpenAlex legal?

Apify's write-up on the legality of web scraping is a good starting point, and we are not lawyers.

🆘 If something breaks

Open the Issues tab on the actor page. Send the run ID, the query and any filter you used. The errorCode on the diagnostic row usually names the problem on its own.
