How to use this tool
This tool estimates capacity, not a fairness policy. Production limits may need separate quotas by consumer, endpoint cost, credential, tenant or commercial agreement.
Return clear rate-limit headers and error responses, protect expensive operations separately and verify that downstream services can absorb permitted bursts.
Planning estimate only. Validate assumptions with workload tests, vendor documentation, architecture review and production monitoring. Browser calculations are not professional engineering or procurement advice.
