LAUDATIO-Repository REST API is one of 9 APIs that [Humboldt-Universität zu Berlin](https://apis.io/providers/humboldt-universitat-zu-berlin/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Research Data, Corpus Linguistics, Open Access, and Repository. The published artifact set on APIs.io includes an OpenAPI specification and an API reference.

Documented, versioned, public read API of the LAUDATIO-Repository (Long-term Access and Usage of Deeply Annotated Information), the open-access research-data repository for historical linguistic corpora operated by HU's Department of Corpus Linguistics with the Computer- und Medienservice. HU publishes its own API reference at /docs/elasticapi naming 32 paths across corpora, documents and annotations; live probe 2026-09-01 returned 30 corpora, 5,284 documents and 1,160 annotation layers. Classified `institution` despite the laudatio-repository.org domain because every ownership signal is HU's: the site imprint and privacy policy point at hu-berlin.de, sign-in authenticates HU accounts against HU's Shibboleth IdP, the source is on HU's own GitLab, and DOIs are minted under HU's DataCite membership as repository tib.hu-laudatio. This surface was missed entirely by the June 2026 profile.
