x402 APIPassing, checked 3 h ago
Field and topic search for research papers. Give a broad field name or short phrase (like 'crispr' or 'exercise science') and get a coherent, taxonomy-grounded seed cluster: the field is resolved against the OpenAlex topics taxonomy, then the cluster returns the top-cited plus recent-influential works, each with title, authors, year, venue, citation count, and DOI. Solves the broad-term entry problem dense semantic search fails on. Keyless.
