Introduction

Liquid Terminal API

The API implements a comprehensive multi-level rate limiting system to protect against abuse and ensure fair usage across all endpoints. The system uses Redis for distributed counting and provides granular control over request frequency.

Rate Limit Configuration

Multi-Level Limits

The system implements three distinct rate limiting tiers:

Tier	Window	Max Requests	Purpose
Burst Limit	1 second	20 requests	Prevents sudden traffic spikes
Minute Limit	60 seconds	1,200 requests	Controls medium-term usage (20 req/sec average)
Hour Limit	3,600 seconds	72,000 requests	Prevents long-term abuse (20 req/sec average)
