Cornell Class Roster API

Public, read-only API (version 2.0) for Cornell Class Roster data: scheduled classes with Course of Study detail, plus configuration lookups for rosters, academic careers, academic groups, class levels and subjects. All methods are GET and return JSON or XML. No authentication. The schedule behind it is maintained by the Cornell Office of the University Registrar and updated daily; the documentation asks clients to stay under one request per second. This is the one unambiguous, institution-engineered public API Cornell operates.

Where this information came from

This is an independent, third-party profile of Cornell Class Roster API, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
