  The only non-production environment DemandScience publishes anywhere on the
  Terminus / DemandScience surface belongs to the Verify API (formerly Lastbounce).
  The Verify API reference names three environments by hostname prefix and states
  which one is the default. No test credentials, no test key prefix, no fixture
  data, no time simulation and no trigger tooling are published, and the
  non-production hosts require the same account API key as production — so this is a
  named environment ladder, not a self-serve sandbox. NOTHING BELOW IS INVENTED:
  every host and label is copied from the provider's own article. The Terminus ABM
  Platform API (api.terminusplatform.com) and the Employee Automation API
  (email.terminusplatform.com) publish no sandbox at all.

  note: >-
    The same account API key is presented as `x-api-key` in every environment. The
    docs do not publish a test-vs-live key prefix, and every verification consumes a
    credit from the account balance, so there is no free/simulated call path.

    No published test fixtures. The docs do publish a sample CSV structure for batch
    uploads (a column whose header contains the word "Email", or bare addresses one
    per line with no header) which is the closest thing to a fixture the provider
    ships.

not_available_for:
- api: Terminus ABM Platform API
  reason: 'No environments published; the reference is behind the developer.terminus.com login and the host returns HTTP 401 on every anonymous path.'
- api: Employee Automation API
  reason: 'No environments published; access is granted only by DemandScience support ticket.'
