    Client-level credentials (Client-Id + Client-Secret) identify the merchant /
    project. Used for General and Payment Initiation Service calls. In the SDK
    this is `new kevin.Client(clientId, clientSecret)`.

  description: >-
    Account Information Service uses a user-authorization flow: `startAuth` (with
    requested scopes + a Redirect-URL) returns an auth key; `receiveToken`
    exchanges the auth key for a bearer + refresh token pair; `refreshToken`
    exchanges a refresh token for a new bearer token; `receiveTokenContent`
    inspects a bearer token. Bearer tokens authorize per-account AIS calls.
  flow: authorizationCode
  operations: [startAuth, receiveToken, refreshToken, receiveTokenContent]

  A2A open-banking (PSD2) provider. Merchant/project auth is header client
  credentials; end-user account access is a scoped, redirect-based token flow.
  No mutualTLS / mTLS scheme was documented in the public SDK. Derived from the
