Xuanlin Q&A provides knowledge retrieval, interpretation and research grounded in classical texts and later scholarship. Users must respect source texts, author rights and applicable law, and must not use the service for infringement, fraud, attacks, bulk abuse or bypassing billing and quotas.

The website and API are provided as available. Billing follows successful usage records; identity questions are not billed. Accounts, sessions and API keys must be protected by their owners. Delete a key or change the password immediately if exposure is suspected.

The service may be briefly unavailable for maintenance, upstream failures or security incidents. We will make reasonable efforts to restore service and preserve correct balances and payment records.
