Rate limits

Surface	Limit
API key requests	100 / minute per key
Auth endpoints (login/register/reset)	20 / hour per IP
Anonymous link creation	configurable per IP (default 10 / hour)
Link-password unlock attempts	10 / 15 min per link + IP

Exceeding a limit returns 429 with a detail message. Back off and retry; for sustained higher throughput, contact us about Enterprise limits.

Tip: batch with the bulk endpoints instead of many single calls to stay well under the per-minute limit.
