- name: Builder Prime Open API
  description: Builder Prime's REST "Open API" — the tenant-scoped integration surface used to create leads and clients, and
    to read clients, employees, projects, appointments, appointment types and appointment results. Authenticated with a per-tenant
    secret key issued from Admin > Integrations > Open API and sent in the x-api-key header; each key is granted named permissions
    (for example clients.create). Resources are individually versioned in the path (/api/<resource>/v1). Builder Prime publishes
    no OpenAPI definition and, as of this probe, no longer publishes a public endpoint reference.

  x-base-url-pattern: https://{subdomain}.builderprime.com
  x-base-url-note: Builder Prime documents a per-tenant base host — the customer's own login subdomain (for example https://johnsfloors.builderprime.com).
    The shared application host app.builderprime.com serves the same /api/<resource>/v1 paths and is recorded here as a real,
    non-placeholder baseURL.
