EZThrottle

EZThrottle is an API rate limit router that manages both outbound and inbound HTTP traffic, solving rate limiting, retries, failover, and fair queuing. It targets developers, operations, and IT teams in B2B settings, especially those with distributed agents sharing API keys. It positions itself as a network routing layer for HTTP, providing per-key queues and multi-region failover, unlike traditional inbound-only infrastructure.
