- `429`: Too many requests from this IP address. The edge allows 100 requests a minute per client IP with a burst of 100, counted across every endpoint together, so sends and status checks share one budget. Accounts that ask for more are raised to 500 a minute; X-RateLimit-Limit on every response tells you which ceiling applies to you. Wait the number of seconds in Retry-After and repeat the request. Write to support@myotp.app with the addresses you call from and the peak you are designing for if you need a higher limit.
