  GUARD publishes a dedicated sandbox (staging) environment for the underwriting
  API. Partners exercise it with alt.bank-provided test CPFs that emulate
  different scoring outcomes (approvals and rejections) before going live in
  production.

    description: >-
      alt.bank provides test CPFs (Brazilian taxpayer registry numbers) in the
      sandbox that emulate different underwriting scenarios, including rejections
      and approvals. The specific CPF values are published only inside the
      partner-gated developer portal and are intentionally not reproduced here.
    values_public: false
notes: >-
  Authentication in sandbox uses the same X-Partner-Auth header scheme as
  production, with a sandbox-scoped partner token. Never invent test CPFs — pull
  the current values from the partner documentation.
