Every response carries X-RateLimit-Limit and X-RateLimit-Remaining. Over the limit you get 429 with a Retry-After header in seconds.

The limit cannot be raised for v1. get-trees returns 100 trees per page, so even a large company syncs in a handful of requests. Sync once a day at most; the trees of a company change a few times a year.
