  title: Vocode Hosted API
  description: >-
    Hosted REST API for the Vocode voice AI platform. Place and manage outbound
    and inbound phone calls driven by configurable voice agents, and manage the
    agents, voices, prompts, actions, phone numbers, and webhooks that power them.
    All requests are authenticated with a Bearer API key. This specification
    covers the hosted API and is distinct from the open-source vocode-core
    Python library.
