URL

You can query OpenAlex directly over raw REST URLs against api.openalex.org. Add parameters to an entity endpoint and you get JSON back — no key required to start.

The core parameters:

  • filter= — narrow to entities matching conditions
  • search= — full-text search
  • sort= — order the results
  • group_by= — aggregate into buckets

A couple of examples:

https://api.openalex.org/works?search=microplastics&sort=cited_by_count:desc
https://api.openalex.org/works?filter=type:book,from_publication_date:2024-01-01

This is the same surface the API tab documents in full. Rather than duplicate it here, see:

  • Filtering — the filter= parameter in detail
  • Searching — the search= parameter and its variants
  • Sorting — ordering results with sort=
  • Grouping — aggregating with group_by=
