Cal.com's managed-user model requires a separate token for each professional in your network. An AI agent routing across 50 therapists needs to manage 50 credentials. Orita gives you one API key with access to your entire provider network.
An AI agent checking availability across 20 providers fires 20 requests in under a second. Cal.com's 60 req/min ceiling creates constant backoff logic at any meaningful scale. Orita's limits are designed for infrastructure workloads.
Cal.com has no API to manage a registry of independent professionals. Each user is a standalone entity. There's no 'book with the first available therapist in Madrid' — you'd have to build that routing layer yourself. Orita provides it.

Yes. Cal.com has a well-documented v2 API that can create bookings, manage event types, check availability, and handle webhooks. It's the most developer-friendly scheduling tool in the market.
Yes. Unlike Calendly, Cal.com's v2 API supports POST /bookings — you can create, reschedule, and cancel appointments programmatically.
Three main constraints: (1) Auth is per-user — each provider needs their own managed token. (2) Rate limits of 60 req/min per key, which creates bottlenecks at scale. (3) No unified provider registry — Cal.com has no concept of a network of professionals.
Cal.com is better if you're embedding scheduling for your own users. Orita is better if you need to route bookings across a network of independent providers — one API key, no per-provider auth, higher rate limits.
