## OpenAPI

````yaml GET /v1/customers
openapi: 3.1.0
info:
  title: Voxfra Management API
  description: >
    Tenant-facing REST API for integrating with Voxfra's voice intelligence
    infrastructure.

    Use this API to read call data, manage clients, and build partner
    dashboards.


    ## Authentication


    All endpoints except `GET /health` require an API key passed in the
    `X-API-Key` header.

    API keys are scoped to a single organization — all responses are
    automatically filtered to your org.


    Keys are issued by your Voxfra account manager or via the Voxfra admin
    console.
