name: Certification (CERT) environment
self_serve: false
access: >-
  CERT access is granted as part of onboarding, not by self-service signup. Credentials are issued through the
  certification client portal and every environment enforces its own IP allowlist, so a CERT integration cannot be
  exercised from an arbitrary source address.
environments:
- mode: certification
  api: https://api.cert.zerohash.com

key_model:
  detail: >-
    There is no test-vs-live key prefix. The same HMAC credential shape (X-SCX-API-KEY + X-SCX-PASSPHRASE + signed
    X-SCX-SIGNED/X-SCX-TIMESTAMP) is used in both environments; separation is by hostname and by a separate key set
    and IP allowlist per environment.

scenario_simulation:
  header: X-Simulator-Scenario
  source: openapi/zero-hash-api-openapi.yml (components.parameters.SimulatorScenario)
  detail: >-
    Optional request header used to simulate specific success and failure scenarios in the certification environment.
    It has no effect in production. The published spec declares it as a free-form string and does not enumerate the
    scenario values, so the usable set requires the CERT documentation or an onboarded account.

gaps:
- >-
  No public sandbox — CERT requires an onboarded account and an allowlisted static IP, so an evaluating developer
  cannot make a first call without a sales conversation.
- >-
  The X-Simulator-Scenario values are not enumerated in the published OpenAPI.
