# Retrieve OpenID Configuration for current Org

GET https://nico-rest-api.nico.svc.cluster.local/v2/org/{org}/nico/site/{siteID}/.well-known/openid-configuration

Public OIDC discovery document pointing at the JWKS URIs. No authentication required.

`id_token_signing_alg_values_supported` is intentionally empty
because NICo issues bearer access JWTs, not OIDC `id_token`s;
strict OIDC client libraries that require a non-empty algorithm
list will reject this document. Use the JWKS endpoint directly
for signature verification. Returns `404` when no identity
material exists for this org/site.
