How it works
The tool computes required requests-per-minute from user behavior and compares it against an API limit to estimate key count and potential blocked traffic.
Formula
required_rpm = active_users * requests_per_user_per_min
required_keys = ceil(required_rpm / limit_rpm)Useful for API gateway planning and integration test constraints.
Example
With 2000 users and 3 requests/min each, required throughput is 6000 RPM.
FAQ
Can I model multiple keys?
Yes, the tool estimates required key count from the configured per-key limit.
Does this include bursts?
No, use burst calculators in parallel for peak scenarios.
Is this only for external APIs?
No. It also helps internal gateway and service-limit planning.
