        API key authentication for public API requests.

        Keys come in two flavors:

        - *Legal-entity-scoped keys* are pinned to a single legal entity.
          Minted via the dashboard under a specific entity; every request
          acts on that entity.
        - *User-scoped keys* are pinned to a user and span every legal
          entity that user has access to. Every request made with a
          user-scoped key (except `GET /legal-entity`, which lists the
          legal entities the user can access) must include an
          `x-legal-entity` header naming the legal entity the request is
          operating on. Requests without the header are rejected with
          `400`. The authenticated user must have an active permission
          role on the supplied legal entity, otherwise the request is
          rejected with `403`.

      description: |
        Partner-program API key authentication.

        Keys are minted in the partner dashboard (Developers → API Keys),
        are scoped to a single partner program, and are prefixed with
        `sk_partner_`. Partner keys are only accepted by routes that
        declare this scheme; they are rejected by `api_key` routes and
        vice versa.
