HeaderDescription
X-RateLimit-LimitMaximum number of requests allowed per time window
X-RateLimit-RemainingNumber of requests remaining in the current window
X-RateLimit-ResetUnix timestamp when the rate limit window resets

Handling Rate Limits

Free Plan: When you exceed your rate limit, Remove Punctuation 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 Remove Punctuation:

  • Monitor the rate limit headers to track your Remove Punctuation usage (Free plan only)
  • Cache remove punctuation responses where appropriate to reduce API calls
  • Upgrade to Pro or Mega for guaranteed no-throttle Remove Punctuation performance

Note: Remove Punctuation rate limits are separate from credit consumption. You may have credits remaining but still hit rate limits when using Remove Punctuation on Free tier.
