Nittei Scheduler API
Nittei is MeetsMore's self-hosted calendar and scheduler server, written in Rust (Axum + SQLx + PostgreSQL) and published under the MIT licence. It exposes a multi-tenant REST API under /api/v1 covering Accounts, Users, Calendars, Calendar Events (with RRULE recurrence), Schedules, Services (bookable resources and booking slots), Reminders and Status, plus Google Calendar and Outlook Calendar sync. The server generates its own OpenAPI document at runtime with utoipa and serves it at /api-docs/openapi.json behind a Swagger UI at /swagger-ui. Because Nittei is distributed as source, a container image and a Helm chart rather than as a hosted service, the host in baseURL is a deployment variable — MeetsMore publishes no public instance, so the generated OpenAPI document cannot be fetched anonymously.
