Linkagi Model Api Authentication

note: >-
  Static API keys minted in the New API console at https://api.linktoagi.com after email verification. No
  OAuth, no OIDC, no SSO, no key rotation contract: GET /api/status reports oidc_enabled=false,
  github_oauth=false, linuxdo_oauth=false, discord_oauth=false, wechat_login=false, passkey_login=false;
  password_login_enabled=true and email_verification=true. /.well-known/openid-configuration and
  /.well-known/oauth-authorization-server are soft-404s (SPA shell), so no scopes/ artifact is emitted.
  The header a key travels in depends on which vendor protocol the route imitates — three schemes, one key.

  group_scoping: >-
    A key belongs to a token group (号池) that determines which models it can address and the billing ratio
    applied. Groups are published unauthenticated at GET /api/pricing (usable_group, group_ratio). This is
    the closest thing LinkAGI has to a scope model.
