How API Rate Limit Tester Works
1. Configure API
Set up your API endpoint, headers, and test parameters including request count and timing.
2. Run Tests
Execute automated requests to test rate limits, monitoring response times and status codes in real-time.
3. Analyze Results
Review detailed results including rate limit headers, response patterns, and performance metrics.
Frequently Asked Questions
What is API rate limiting?
API rate limiting controls how many requests a client can make to an API within a specific time period. It prevents abuse, ensures fair usage, and maintains API performance and availability.
How does the rate limit tester work?
The tool sends multiple HTTP requests to your API endpoint and monitors responses, tracking status codes, response times, and rate limit headers like X-RateLimit-Remaining and X-RateLimit-Reset.
What rate limit headers are detected?
The tool detects common rate limit headers including X-RateLimit-Limit, X-RateLimit-Remaining, X-RateLimit-Reset, Retry-After, and custom headers used by various API providers.
Is it safe to test APIs with this tool?
The tool runs entirely in your browser. Be mindful of API terms of service and rate limits. Start with low request counts and respect rate limits to avoid being blocked by the API provider.
