Search the high-energy-physics literature by API
INSPIRE is the reference database for high-energy physics, and its REST API lets you query papers, authors, and citations. A literature search returns hit metadata like titles and author affiliations as JSON. Open access to millions of HEP records with no login.
We probe a documented GET and expect 2xx JSON — full uptime and health score. Open provider docs ↗
