## 错误与安全重试

检查 HTTP 状态和响应正文。400 验证错误可能包含 ZodError；处理程序错误使用 error、message 和 code 字段。保留 request_id 或 x-request-id 以便诊断，但不要保留凭证。先解决 401/403 访问错误再重试，并在收到 429 时遵循 Retry-After。如写入结果不确定或返回 5xx，先读取现有结果。仅在支持时复用幂等键；重试行为因操作而异，并不保证恰好交付一次。

## 示例

这些示例使用已依schema检查的虚构值。请将 ID 替换为你有权使用的 ID、将媒体替换为已就绪素材，并将日期替换为已确认的发布时间。提交写入前，请检查账号资格。本页不会发送 API 请求。

在服务器上将 SOSOAPI_ACCESS_TOKEN 设为此操作接受的凭证，且不要放入浏览器代码。agent 请使用 sosoapi auth login 通过浏览器登录，并由 CLI 更新凭证。
