Vymo Rate Limits

Vymo publishes no rate-limit documentation. The API reference that would carry limits and the runtime response headers is on a private Read the Docs Business site (https://docs.getvymo.com/), which returns "Log in to view this documentation" and redirects anonymous requests to app.readthedocs.com/accounts/login/. No limits could be observed live either: https://app.lms.getvymo.com returns {"authentication_error":"unauthorized"} on every path and emits no X-RateLimit-*, RateLimit-* or Retry-After header on the anonymous rejection. An honest zero: limits may well exist for customers, but nothing about them is public.
