Get lists of sources

You can get lists of sources:

• Get all sources in OpenAlex
  https://api.openalex.org/sources

Which returns a response like this:

{
    "meta": {
        "count": 226727,
        "db_response_time_ms": 32,
        "page": 1,
        "per_page": 25
    },
    "results": [
        {
            "id": "https://openalex.org/S2764455111",
            "issn_l": null,
            "issn": null,
            "display_name": "PubMed Central",
            // more fields (removed to save space)
        },

        },
        // more results (removed to save space)
    ],
    "group_by": []
}

Page and sort sources

By default we return 25 results per page. You can change this default and page through sources with the per-page and page parameters:

• Get the second page of sources results, with 50 results returned per page
  https://api.openalex.org/sources?per-page=50&page=2

You also can sort results with the sort parameter:

• Sort sources by cited by count, descending
  https://api.openalex.org/sources?sort=cited\_by\_count:desc

Continue on to learn how you can filter and search lists of sources.

Sample sources

You can use sample to get a random batch of sources. Read more about sampling and how to add a seed value here.

• Get 10 random sources
  https://api.openalex.org/sources?sample=10

You can use select to limit the fields that are returned in a list of sources. More details are here.
