Kuaishou Authentication

notes: >-
  Verified by live HTTP probe on 2026-07-19. The Kuaishou Open Platform developer documentation is served
  as a JavaScript single-page application and its written scope/permission reference is gated behind
  developer registration, so only the endpoints and behaviours observed directly on the wire are recorded
  here. No scope list is asserted because none could be verified without an approved developer account.

      authorization_endpoint_behaviour: >-
        Returns the Kuaishou Open Platform authorization / login interface, consistent with an OAuth 2.0
        authorization-code front channel.

      token_endpoint_unparameterised_response: >-
        {"result":100200100,"error":"invalid_request","error_msg":"请求参数错误，请检查参数是否合法"}
      token_endpoint_note: >-
        The token endpoint answers an unparameterised request with the OAuth 2.0 `invalid_request` error
        identifier wrapped in Kuaishou's own result/error_msg envelope.

        {"timestamp":"...","status":404,"error":"Not Found","message":"No message available",
        "path":"/rest/n/mapi/..."}
      note: >-
        The host routes /rest/n/mapi/* through a JSON application server, but no authorization or token
        endpoint could be confirmed without an approved Kwai for Business advertiser account. No scheme
        is asserted.
gaps:
- No /.well-known/openid-configuration or /.well-known/oauth-authorization-server document is published
  on any Kuaishou or Kwai host (all requests are absorbed by the SPA catch-all; see
  well-known/kuaishou-well-known.yml).
- No public OAuth scope / permission reference could be retrieved; scopes/ is intentionally not produced
  rather than fabricated.
