Answer: meta.count and results, each with OpenAlex id, doi, title, publicationyear and date, type, authorships (authors with institutions), primarylocation (journal or repository), citedbycount, openaccess (isoa, oaurl), language and topics. Abstracts left out. filter takes OpenAlex filter syntax, e.g. publicationyear:2024,isoa:true or authorships.institutions.ror:https://ror.org/01an7q238. sort e.g. citedbycount:desc. Data from OpenAlex (openalex.org, by OurResearch), CC0: no attribution required, citing OpenAlex is appreciated. Free, no key, but the free daily budget is shared, so a 429 (ratelimited, $0) means try again tomorrow.
