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 conditionssearch=— full-text searchsort=— order the resultsgroup_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:
