API Rate Limiting controls the number of requests a user can make to a server within a specific time frame. In the cryptocurrency space, this helps prevent abuse and ensures fair access to resources. For example, exchanges may set limits on how many times a user can query market data or execute trades in a minute or hour. This protects the service from overload and ensures that all users have a chance to access the system without delays or crashes.Rate limits can vary based on the service tier, user account type, or specific APIs being accessed. Some systems offer higher limits for premium users, while others may apply stricter limits to free tiers. By managing API requests, services can maintain stability and performance, safeguarding both the server and its users from potential disruptions.
