Get a single work

It's easy to get a work from from the API with: /works/<entity_id> Here's an example:

• Get the work with the OpenAlex ID W2741809807: https://api.openalex.org/works/W2741809807

That will return a Work object, describing everything OpenAlex knows about the work with that ID.

{
    "id": "https://openalex.org/W2741809807",
    "doi": "https://doi.org/10.7717/peerj.4375",
    "title": "The state of OA: a large-scale analysis of the prevalence and impact of Open Access articles",
    "display_name": "The state of OA: a large-scale analysis of the prevalence and impact of Open Access articles",
    "publication_year": 2018,
    "publication_date": "2018-02-13",
    // other fields removed for brevity
}

You can make up to 50 of these queries at once by requesting a list of entities and filtering on IDs using OR syntax (tutorial).

External IDs

You can look up works using external IDs such as a DOI:

• Get the work with this DOI: https://doi.org/10.7717/peerj.4375: https://api.openalex.org/works/https://doi.org/10.7717/peerj.4375

You can use the full ID or a shorter Uniform Resource Name (URN) format like so:

• Get the work with PubMed ID: https://pubmed.ncbi.nlm.nih.gov/14907713: https://api.openalex.org/works/pmid:14907713

Available external IDs for works are:

External ID	URN
DOI	doi
Microsoft Academic Graph (MAG)	mag
PubMed ID (PMID)	pmid
PubMed Central ID (PMCID)	pmcid

You must make sure that the ID(s) you supply are valid and correct. If an ID you request is incorrect, you will get no result. If you request an illegal ID—such as one containing a , or &, the query will fail and you will get a 403 error.

Select fields

You can use select to limit the fields that are returned in a work object. More details are here.
