implementing-api-rate-limiting-and-throttling
Implements API rate limiting and throttling with token bucket, sliding window, and fixed window algorithms, configuring per-user, per-IP, and per-endpoint limits via Redis-backed counters, API gateway plugins, or middleware, and returning proper HTTP 429 responses with Retry-After headers. Use when setting up request quota management or preventing brute force, credential stuffing, and resource exhaustion attacks against APIs.

# Implementing API Rate Limiting and Throttling
## When to Use
- Protecting authentication endpoints against brute force and credential stuffing attacks
- Preventing API abuse and resource exhaustion from automated scripts and bots
- Implementing fair usage quotas for different API consumer tiers (free, premium, enterprise)
- Defending against denial-of-service attacks at the application layer
- Meeting compliance requirements that mandate API abuse prevention controls
**Do not use** rate limiting as the sole defense against attacks. Combine with authentication, authorization, and WAF rules.
## Prerequisites
- Redis 6.0+ for distributed rate limit counters (or in-memory for single-instance deployments)
