Frequently Asked Questions

Which APIs can I test?

Any REST API accessible via HTTP/HTTPS. Configure custom headers, auth tokens, and request payloads to match your target API requirements.

How does the rate limit detection work?

The tester analyzes HTTP 429 responses, Retry-After headers, X-RateLimit-* headers, and response timing patterns to map out exact rate limit windows and thresholds.

Is my API key or data stored?

Test configurations are stored only for your session. No API keys or response payloads are persisted beyond your active test run.
