Get a single work

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

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:

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

Available external IDs for works are:

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 IDβ€”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.
