  experience company whose NextOS / NEXT platform combines UCaaS business phone service,
  contact center (NCX), SMS and team messaging, voice AI agents, and conversation

  publishing five REST OpenAPI 3.0 contracts (Provider Authentication, Provider Token
  Service, Workitem Service, Conversation, SMS Messaging) served from api.nextiva.com,
