  update:
    description: Azure API Management subscription key. Request one per API from the Casey's developer
      portal at https://developer.esl.caseys.io/ (sign-in required). Each API is fronted by its own APIM
      product, so a key for one API does not authorise another.

  description: Record the agent-safety properties of this write, which the contract does not state.
  update:
    x-idempotency: none
    x-reversible: false
    x-agent-note: No Idempotency-Key mechanism and no reversal operation is published for this write.
      A retry after a timeout may duplicate the effect and it cannot be undone through the API.
