This pulls from OpenAlex's 240 million scholarly works via direct REST API calls. No API key, just curl with mailto parameter for the polite pool. You get title, abstract, citation counts, open access links, authors, and DOIs. Search supports boolean operators, filter by year/citations/OA status/type, and sort by relevance or citation count. The abstract comes as an inverted index you need to reconstruct, which is quirky but documented. Most useful when you need peer-reviewed sources during research or want to find highly cited papers in a domain without hitting paywalls or rate limits. Beats scraping Google Scholar.
