Contact support

What can AI support do, and who pays?

AI support is restricted to LINGJING usage and configuration. It cannot perform unrelated tasks, refunds or permission changes. LINGJING pays; customer balance is not deducted. Each account has a daily procurement-cost cap of USD20, resetting at midnight Beijing time. Free documentation remains available afterwards. Out-of-scope requests are screened before model calls; contact human support for disputes.

How do I troubleshoot?

401: check the full key. 403: model permissions. 400: parameters, history and context. 409: inspect the original request. 429: reduce concurrency and honor Retry-After. For 5xx or timeouts, inspect usage before retrying. Copy the full newly created key, not its abbreviated list prefix. Revoke suspected leaked keys. Never send passwords, verification codes or full keys to support.
