Builder Prime Open API
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//v1). Builder Prime publishes no OpenAPI definition and, as of this probe, no longer publishes a public endpoint reference.
