Developer API
Effective August 20, 2026. These terms apply when you use the hosted Exergy Factor API.
You may use the free public beta for testing, prototypes, research, education, and early integrations. Do not use the service to violate law, interfere with the service, evade limits, or attempt unauthorized access. Supported commercial or high-volume use may require a separate plan.
Outputs are deterministic calculations and screening information based on the inputs, reference conditions, boundaries, and methods reported with each result. They are not measurements, site-specific designs, equipment guarantees, professional engineering advice, or a substitute for verification by a qualified professional. You are responsible for checking that inputs, units, assumptions, and outputs are suitable for your use.
The service is provided as available. Free hosting may sleep after inactivity, and limits, endpoints, reference data, and these terms may change as the service develops. We may throttle or suspend access used abusively or in breach of these terms. Material calculation changes will be identified through API or schema versioning where applicable.
The public beta does not issue or require API keys. The hosting provider may retain ordinary request logs for security and operations. Do not submit confidential, regulated, or personal data in calculation requests.
The API and its outputs are provided without warranties of accuracy, fitness for a particular purpose, or uninterrupted availability, to the extent permitted by law. To the extent permitted by law, the service authors and operators are not liable for indirect, incidental, special, consequential, or business losses arising from use of the service or reliance on its outputs.
The underlying Quantity and Quality software has its own open-source license. These API terms govern access to the hosted service and do not replace the license that applies when you run the software yourself.
