Rate Limit Headers
When rate limits apply, each Username Profanity response includes headers to help you track your usage:

X-RateLimit-Remaining | Number of requests remaining in the current window |
X-RateLimit-Reset | Unix timestamp when the rate limit window resets |
Handling Rate Limits
Free Plan: When you exceed your rate limit, Username Profanity returns a 429 Too Many Requests status code. Your application should implement appropriate backoff logic to handle this gracefully.
Paid Plans: No rate limiting or throttling applied. All paid plans (Starter, Pro, Mega) are production-ready.
Best Practices for Username Profanity:
- Monitor the rate limit headers to track your Username Profanity usage (Free plan only)
- Cache username profanity responses where appropriate to reduce API calls
- Upgrade to Pro or Mega for guaranteed no-throttle Username Profanity performance
Note: Username Profanity rate limits are separate from credit consumption. You may have credits remaining but still hit rate limits when using Username Profanity on Free tier.
