  title: API Evangelist enrichment overlay — VoyantIO API
  version: 1.0.0
  x-description: >-
    Applies the enrichment findings for the VoyantIO API back onto the provider's own
    783-operation OpenAPI without mutating it. Every value below is sourced from an artifact in
    this repo or from a probe recorded in one; nothing is invented. Apply with an Overlay 1.0.0
    processor against openapi/voyant-openapi-original.json.

            name; GET / answers "VoiceForge API is running with automated RAG" version 0.2.0
