Missing rate limit headers

owasp:api4:2019-rate-limit

Rule Severity:

High

Endpoints should use proper rate limiting to ensure service availability to all users.
This rule applies at the API Specification level (OAS/Swagger).
Include 'X-RateLimit-Limit', 'X-Rate-Limit-Limit', 'RateLimit-Limit' or 'RateLimit-Reset' in the HTTP headers to avoid unintended service disruption.
