## HTTP 429 Errors

HTTP 429 Errors, or Too Many Requests, are the standard response code an API sends when a user has exceeded their rate limit. Receiving this error indicates that the trader's system is sending requests faster than the exchange allows.

This is a signal to slow down and implement a back-off strategy. Ignoring these errors can lead to further penalties, such as temporary IP bans or account restrictions.

Traders must build their API clients to detect 429 errors and automatically adjust their request frequency. This is a fundamental requirement for robust API interaction.

Proper handling of 429 errors ensures that the trading system remains compliant and avoids unnecessary service disruptions.
