IIT Delhi Departmental Site Platform API
Undocumented JSON API behind the shared React/Express site platform IIT Delhi runs across departmental and unit subdomains. Anonymous reads were confirmed on 2026-08-30 across three deployments — convocation.iitd.ac.in serves /api/news and /api/contact, ird.iitd.ac.in serves /api/contact, /api/circulars and /api/announcements, and csc.iitd.ac.in serves /api/contact and /api/pages. Media collections and writes are gated behind the institute's own OAuth 2 server, which the API names in its own 401 body. IIT Delhi publishes no documentation, version marker, changelog or contract for this surface; the OpenAPI in this repo was reverse-described entirely from live probes and is marked as such.
