POSTECH LMS (PLMS) LTI 1.3 Advantage Platform is one of 5 APIs that [Pohang University of Science and Technology](https://apis.io/providers/postech/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include LTI, Learning Management System, Moodle, Authentication, and JWKS. The published artifact set on APIs.io includes authentication docs.

POSTECH's learning management system is an institution-hosted Moodle (coursemos distribution) acting as an LTI 1.3 Advantage platform, and unusually for this cohort its platform endpoints are publicly reachable. The JSON Web Key Set at /mod/lti/certs.php returns a real RSA RS256 key (kid 13acf24233904ff6db00) with no credentials — the keyset an external tool needs to verify POSTECH-issued id_tokens — and the paired OAuth 2.0 token service at /mod/lti/token.php answers an unparameterised request with an RFC 6749 invalid_request object rather than an HTML page. Tool registration itself is an LMS administrator action and is not open to outside developers.
