Tests API rate limiting for bypass vulnerabilities using Python (requests/aiohttp) and Burp Suite Turbo Intruder to manipulate headers (e.g. X-Forwarded-For spoofing), IPs, HTTP methods, API versions, and encodings, mapping findings to OWASP API4:2023 Unrestricted Resource Consumption. Use when assessing, under written authorization, whether rate limits can be bypassed to enable brute force or resource-exhaustion attacks.

# Performing API Rate Limiting Bypass
## When to Use
- Testing whether API rate limiting can be circumvented to enable brute force attacks on authentication endpoints
- Assessing the effectiveness of API throttling controls against credential stuffing or account enumeration
- Evaluating if rate limits are enforced consistently across all API versions, methods, and encoding formats
- Testing if API gateway rate limiting can be bypassed through header manipulation or IP rotation
- Validating that rate limits protect against resource exhaustion and denial-of-service conditions
**Do not use** without written authorization. Rate limit testing involves sending high volumes of requests that may impact service availability.
## Prerequisites
- Written authorization specifying target endpoints and acceptable request volumes
