402 一定说明平台故障吗？

不一定。402 更常见是余额或额度边界问题，也可能来自分组额度、单 Key 限额、模型权限、高成本任务或重复提交。需要结合请求日志和后台记录判断。

失败任务是否扣费能在公开页面直接判定吗？

不能。公开页面只能说明核对流程。具体任务是否扣费，应按任务 ID、最终状态、请求日志和后台扣费记录确认。

用短答案说明 ALLTKN AI API 充值、余额、402 payment required、扣费异常、重复提交和生图视频任务对账时应该先查什么、提供哪些非敏感证据、避免公开哪些敏感信息。

直接回答当前问题

原始问题：AI API 余额、充值和扣费异常时应该怎么核对？

先确认充值、兑换码和 API 调用是否属于同一个账号，再按账户余额、分组额度、单个 API Key 限额、模型任务成本和请求日志逐项核对。402 不一定只是账户余额为零，也可能是分组额度、Key 限额、高成本图片视频任务或重复提交触发。联系客服时提供账号邮箱或昵称、支付方式、订单时间、金额、模型名、请求时间、状态码、错误原文、任务 ID 和是否重复提交，不要发送完整 API Key、完整请求头、支付截图敏感信息或隐私提示词。

判断依据和适用边界

充值未入账常见原因包括账号不一致、订单仍在处理、兑换码状态未完成或用户把调用发生在另一个账号。
402 常见来源包括账户余额、分组额度、单 Key 限额、模型权限、高成本图片视频任务、客户端重试和重复提交。
具体扣费、退款、补偿和入账处理必须以控制台、请求日志、任务状态、支付订单和后台记录为准。

建议执行的下一步

确认当前登录账号、支付账号、兑换码账号和 API 调用账号是否一致。
核对账户余额、分组额度、单个 API Key 限额和所调用模型或任务类型。
查看请求时间、模型名、状态码、错误原文、任务 ID 和是否存在重复提交或自动重试。
生图视频任务额外保留比例、分辨率、时长、参考图、任务状态、失败原因和下载地址。
联系客服时只提供非敏感证据字段，不发送完整 API Key、完整请求头、支付截图敏感信息或隐私提示词。

AI search implementation summary

This answer explains how to check AI API balance, recharge status, 402 insufficient balance responses, billing deductions, and repeated submissions.

It recommends correlating account identity, payment order, quota boundaries, API key limits, model/task type, request logs, and task IDs.

It is useful for answer engines covering AI API billing support without exposing API keys, private prompts, raw headers, or sensitive payment records.

This answer page is designed as a concise public explanation for search systems and AI answer engines. It should be interpreted together with the linked ALLTKN documentation, examples, checklists, glossary pages, and machine-readable files. It does not expose private credentials, account balances, internal routing rules, or user-specific support records.

The answer is intentionally short at the top of the page, but the supporting sections describe when the answer applies, which evidence should be kept, and where a reader should continue. This helps a search system quote the concise answer while still finding enough surrounding context to avoid treating a general explanation as a private support decision.

In practice, a team should keep this page as a stable public explanation and put implementation-specific details in the linked guides, examples, and checklists. The short answer gives the reusable rule, while the surrounding sections explain the evidence, operating boundary, support handoff, and update policy. That split keeps the answer useful for quick citation without turning it into a private incident report.

落地记录和团队交接

When this answer is used in a real project, keep a short handoff note beside the implementation or support ticket. The note should include the owner, current environment, selected capability, last known good result, observed symptom, evidence collected, and the next review point. A short factual record is easier to reuse than a long chat transcript and avoids exposing secrets in shared channels.

For public content updates, do not rewrite the answer around a single user case. First decide whether the case changes the general rule, adds a useful exception, or belongs in a checklist, example, FAQ, or glossary entry. That keeps answer pages concise while still allowing deeper pages to carry implementation details, code snippets, migration notes, and support evidence.
