École Normale Supérieure de Paris (ENS, rue d'Ulm) is a leading French grande école and constituent member of Université PSL (Paris Sciences & Lettres), ranked #86 in the QS World University Rankings 2025. ENS operates 15 departments, 35 research laboratories and a network of libraries. ENS does not publish a first-party developer portal or documented institutional API; its programmatic surface is reached indirectly via national French research and higher-education open infrastructure. Researcher output is deposited in the HAL-ENS open archive, which is harvestable through the national HAL OAI-PMH endpoint and the HAL REST/Search API, and ENS establishment data is exposed through the Ministry of Higher Education (MESR) open-data platform's Opendatasoft Explore API.
