Terms of service
The terms that apply when you use the public x-ziwei service and this site.
Effective date: 12 November 2026
x-ziwei is an open-source project maintained by x-haose as an individual. By using the public service at https://ziwei-mcp.x-haose.com or this site, you agree to these terms.
What the service is
The service computes a Zi Wei Dou Shu chart from the birth information you give it and provides an open knowledge pack for reference. It does not generate readings: the reading is produced by the AI model you use.
Free, with no availability guarantee
- The service is public and free and needs no account. You may call it directly or build it into your own product, including a paid one.
- The service is provided as is. It may slow down, be interrupted, rate limited, changed or discontinued without notice, and the availability of data is not guaranteed.
- Where you need stability, host it yourself or use the x-iztro library directly.
Acceptable use
- Do not call the service at a rate clearly beyond normal use, and do not try to bypass rate limits or interfere with its operation.
- Do not use the service for unlawful activity or to infringe the rights of others.
- Before submitting another person's birth information, make sure you are entitled to do so.
We may limit or refuse access where these requirements are not met.
The nature of the results
- A chart is a computed result. It is cast by published rules and matches iztro's output field for field. That means the computation is consistent, not that a reading is accurate.
- The knowledge pack is one reference view. Schools differ, and the default pack is not the only way to read a chart.
- Readings come from your AI model. x-ziwei does not control and is not responsible for what the model says.
Zi Wei Dou Shu is traditional cultural content, and results are for cultural interest and reference only. They are not medical, legal, financial, psychological or other professional advice and should not be the basis for significant decisions.
Open-source licences
The service's source code is published under the MIT licence on GitHub. The default knowledge pack derives from iztro-docs (MIT, by Sylar Long), edited and rewritten; when you use its content, keep the source attribution carried in the pack.
Limitation of liability
To the extent permitted by law, the service comes with no warranty, express or implied. The maintainer is not liable for any loss arising from the use of, or inability to use, the service.
Changes and contact
When these terms change, this page and the effective date above are updated; continued use means acceptance. For questions, open an issue at GitHub Issues.
