  0-working/derive-authentication.py produced no profile for this provider: not one of the four
  harvested specifications declares an OpenAPI securityScheme. Airtel IoT sets `security: []` at
  the document root, Airtel Locate models its bearer token as a plain required `access_token`
  header PARAMETER on every operation instead of a securityScheme, and both Airtel IQ Swagger 2.0
  documents omit securityDefinitions entirely. The auth model below is therefore SEARCHED from
  Airtel's published documentation and from the token-issuing operations that do appear in the
  specifications — it is real, but it is not machine-readable from the specs, which is itself the
  finding.

    token_transport:

      parameter: access_token
      note: >-
        Every non-token Locate operation declares a REQUIRED `access_token` header parameter. This
        is not an RFC 6750 Authorization: Bearer header and is not declared as a securityScheme.

    layered_authorization:
      model: per-subscriber consent
      note: >-
        A valid access token is NOT sufficient to read a location. Airtel Locate additionally
        requires explicit per-MSISDN subscriber consent captured over SMS or IVR before
        getLocationUsingGET_3 will return a position; a resource that has not consented returns
        403 with "resource has not given consent".

      The 2017 Smart API partner documentation publishes both grant types with
      `?scope={scope}&client_id={client_id}&response_type=code|token&state={state}` authorization
      requests and worked examples using scope=ChargeAmount and scope=subscription. Production
      hosts are redacted to <IP>:<Port>; the portal is unmaintained (2017 copyright).

    No /.well-known/openid-configuration is served on www.airtel.in, openapi.airtel.in or
    m2m.airteliot.co.in (all HTTP 404). developers.airtel.in returns HTTP 200 for the path but
    serves its SPA HTML shell, not a discovery document.
ciba:

  note: >-
    CIBA (Client-Initiated Backchannel Authentication), which CAMARA pairs with OIDC for
    network-based authorization, appears nowhere in Airtel's public surface. Consistent with the
    finding that Airtel operates no first-party CAMARA authorization surface.
