What it does

Crossref is a not-for-profit membership organisation that indexes metadata for ~185 million scholarly works. This actor wraps the keyless https://api.crossref.org/works endpoint so you can retrieve structured metadata — titles, authors, publishers, publication dates, journal/ISNN, citation counts, and source URLs — as rows in an Apify dataset.

Input

Field	Type	Default	Description
`query`	string	`""`	Free-text search across title / abstract / keywords.
`doi`	string	`""`	A single DOI to resolve (e.g. `10.1038/nature12345`). Overrides query/filter.
`filter`	string	`""`	Crossref filter expression — e.g. `type:journal-article`, `from-pub-date:2024`, `issn:0028-0836`.
`maxWorks`	integer	`10` (1–100)	Max works to return in search mode.

Only one of doi, query, or filter is needed. If all are empty the actor defaults to fetching the 10 most recent journal-articles.

Examples

{
  "query": "graph neural network",
  "maxWorks": 20
}

{
  "doi": "10.1103/PhysRevLett.116.061102"
}

{
  "filter": "from-pub-date:2024-01,type:journal-article",
  "maxWorks": 50
}

Output

Each row in the dataset represents one scholarly work:

Field	Description
`doi`	The DOI of the work.
`title`	Title of the work.
`authors`	Comma-separated author list with ORCID IDs if present.
`publisher`	Publisher name.
`published`	Publication date (YYYY-MM-DD, YYYY-MM, or YYYY).
`type`	Work type (journal-article, book, book-chapter, etc.).
`citationCount`	Number of citing works (if available).
`journal`	Container / journal title.
`issn`	ISSN(s) of the journal.
`url`	Canonical URL for the work.
`error`	Empty on success, populated if the work could not be fetched.

Billing

PAY_PER_EVENT per scholarly-work-fetched event — one charge per work emitted to the dataset. Batch mode (maxWorks) lets a single run bill for up to 100 works.

Notes

The Crossref API is keyless and generous with rate limits (~no-auth requests).
The actor sends a descriptive User-Agent header as required by the Crossref API policy.
A proper email should be supplied in the User-Agent for production use; the current default is a placeholder.
