🧬 PubMed Scraper — Biomedical Literature & Citation Metadata as Clean Data

Extract biomedical citations from PubMed — the U.S. National Library of Medicine's database of tens of millions of life-sciences articles — as clean, structured records, powered by the official NCBI E-utilities API. Search any term like crispr or cancer immunotherapy, use PubMed field tags such as covid-19 AND vaccine[Title], and get titles, authors, journals, dates, DOIs, PMIDs, article types and links, no API key, proxy or browser required. Export to JSON/CSV/Excel, run on a schedule, call via API, or connect to Make, Zapier or n8n.

🧬 What is the PubMed Scraper?

It turns any PubMed search into a structured dataset. Give it a search term (with optional PubMed field tags and sort order) and it returns every matching article with authors, journal, publication date, DOI, PMID and direct links — flattened into clean rows so you can drop them straight into a systematic review, reference manager or clinical database. It runs the official two-step E-utilities flow (esearch to find PMIDs, esummary to fetch details), paginates in batches and waits between requests to respect NCBI's rate limits, so a request for hundreds or thousands of articles just works.

What data does it extract?

• Identifiers — pmid, doi, doi_url, pmc_id
• Title — the article title
• Authors — authors, author_count and last_author
• Journal — journal, journal_abbr and issn
• Publication details — pub_date, epub_date, volume, issue, pages
• Type & language — pub_type and language
• Links — url (PubMed page) and doi_url
• Run metadata — search_query and scraped_at

⬇️ Input

Search with a plain term or PubMed field tags, then choose a sort order:

Field	Description
searchQuery	PubMed search term; supports field tags, e.g. crispr, cancer immunotherapy, covid-19 AND vaccine[Title] (required)
sortBy	relevance, newest (publication date) or most_recent
maxResults	Cap the run (1–10000)

Example input

{
  "searchQuery": "crispr cas9 AND cancer[Title]",
  "sortBy": "newest",
  "maxResults": 100
}

• 🩺 Literature monitoring: track new publications on a disease, drug or method by re-running a saved query on a schedule.
• 📊 Bibliometrics: analyse journals, authors, article types and publication trends across a field.
• 🗂️ Clinical & research databases: enrich internal records with authoritative PubMed metadata and links.

❓ FAQ

How do I search PubMed with this Actor? Enter a searchQuery, optionally choose a sortBy order, then Run. You get structured articles with title, authors, journal, publication date, DOI, PMID and links.

Can I use PubMed field tags and boolean operators? Yes. The searchQuery is passed straight to PubMed, so tags like [Title], [Author] or [MeSH Terms] and operators like AND, OR and NOT all work, for example cancer immunotherapy AND 2025[pdat].

Do I need an API key? No. The Actor uses the free, official NCBI PubMed E-utilities API with no key, login, proxy or browser. It waits between requests to stay within NCBI's limit of about 3 requests per second.

What database does it cover? PubMed, the U.S. National Library of Medicine's index of biomedical and life-sciences literature, including MEDLINE journal articles, reviews and more.

Can I sort by newest? Yes. Use sortBy: newest to order by publication date or sortBy: most_recent for the most recently added records; relevance uses PubMed's default ranking.

How many articles can it return? Up to your maxResults cap (1–10000). It fetches results in batches and paginates automatically.

Do I get DOI and full-text links? Yes. Each record includes the pmid and PubMed url, plus a doi and doi_url, and a pmc_id for PubMed Central when one exists.

Why are some fields empty? PubMed does not record every detail for every article — some entries lack a DOI, volume, issue or PMC ID. The Actor returns whatever the source provides. Note that PubMed metadata does not include full abstracts in this summary view.

Can I run it on a schedule or via API? Yes. Schedule recurring runs in Apify, call it via the API/SDK, or connect it to Make, Zapier or n8n to push results into your own tools.

Is scraping PubMed legal? The Actor uses the official NCBI E-utilities API, which is provided for programmatic access to public data. Use it responsibly, follow NCBI's usage policy and rate limits, and comply with applicable laws.
