Shoonya annotation platform API (AI4Bharat, IIT Madras)
A Django REST Framework API operated by AI4Bharat, IIT Madras's language-AI centre, behind the Shoonya data-annotation platform. The API root returns a browsable JSON index of /task/, /annotation/ and /prediction/; each of those returns HTTP 401 {"detail":"Authentication credentials were not provided."}. A drf-yasg documentation surface is live at /swagger/ ("Shoonya API Docs") and /redoc, but the generated specification at /swagger.json, /swagger.yaml and /swagger/?format=openapi all return HTTP 500 — the docs render and the machine-readable contract does not. Recorded as an institution-operated API with no retrievable specification rather than padded with one we do not have.
