Dartmouth Class Search API
The JSON backend of Dartmouth Class Search, the institution's public timetable of class meetings. Keyless: an unauthenticated POST returned 1393 sections for term 202609 on 2026-08-30. Two routes — search and details — selected by query parameter, with a JSON criteria body. Dartmouth operates it on its own host and does not publish it as an API, document it, or offer any stability commitment; the OpenAPI here is a probed description, not a contract Dartmouth authored. Errors arrive inside HTTP 200 as a `fatal` member.

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.
