Tongji University Open Platform
The university's own institutional data and capability API platform, operated by the Tongji University Information Office. Roughly 234 documented interfaces across fifteen families: personnel, student, teacher, teaching management, research, school management, library, campus-card and access control, asset and procurement, education-data verification, AI services, notifications, calendar, cloud meeting and electronic signature. Routes carry a version segment (/v1/, /v2/) and a delivery-mode segment — `rt` for real-time queries against the system of record, `dc` for warehouse-served batch data, `infra` for shared campus capabilities, `metadata` for reference code tables. Interfaces are called with an OAuth 2.0 bearer token from the platform's Keycloak realm under either client-credentials or authorization-code mode; thirteen reference-metadata interfaces need no credential at all and were confirmed callable on 2026-09-01. Rate limiting is a documented token bucket at 50 requests per second per application per IP, with 429 on exhaustion. Notably, every interface page names the upstream system of record it draws from — a provenance practice most university platforms do not have.

Paths & Operations 13
Across 13 paths, the API surfaces 13 operations — 13 GET. Each is listed below with its method, path, parameters, and response codes.
Openly callable code tables (metadata dictionaries) that define the controlled vocabularies used across every other Open Platform interface.
Schemas 14
The contract defines 14 schemas that model the data the API accepts and returns. The most detailed are V2MetadataStudentAccomBuildingCodeItem (8 properties), V1MetadataAssetCampusGateItem (7 properties), V2MetadataStudentAccomRegionCodeItem (6 properties), V1MetadataTeacherTechJobCodeItem (5 properties). Each schema is shown below with its type and property counts.
