bonndoc DSpace REST API (bot-challenged)
bonndoc runs DSpace 7-class software, which exposes a HAL/JSON REST API at /server/api. It is recorded with an honest limit rather than as a working surface: on 2026-09-01 https://bonndoc.ulb.uni-bonn.de/server/api returned HTTP 200 carrying a 4,475-byte Anubis proof-of-work interstitial titled "Making sure you're not a bot!", not JSON. The same challenge is served for /xmlui/OAI/request and for the site root. This is a soft-200 and is NOT credited as a live REST surface; the /oai/request path is the exception and answers real OAI-PMH XML. No DSpace specification is saved under this institution.
