description: Montran APIs ship inside on-premise / private-cloud deployments at central banks and commercial
  banks; rate limits are sized by the operator to scheme requirements (e.g. instant-payment scheme TPS targets,
  RTGS throughput SLAs). Montran does not publish a public rate-limit document because the limits are
  set per-deployment.

notes: No public rate-limit document. Limits will be defined in the deployment's non-functional requirements
  / scheme conformance specification.
responseCodes:

limits:
  - name: Deployment-defined throughput
    scope: deployment
    metric: varies
    limit: see deployment NFRs
    notes: Sized to scheme TPS / SLA (e.g. SCT Inst, FedNow, TIPS, RTP scheme requirements).
policies:
  - name: Scheme conformance
    description: Throughput, latency, and availability targets follow the host scheme's conformance specification
      (e.g. TIPS, SCT Inst, FedNow, RTP) rather than a Montran-published default.
  - name: Operator responsibility
    description: The deploying institution (central bank or commercial bank) sizes infrastructure and
      configures any internal rate-limit policy on top of Montran's gateway.
