概览

通过 id 读取单个素材：元数据及短期有效的预览 URL。

成功 HTTP 响应可能表示请求已接受，并非已完成。背景工作请存储返回 ID，持续检查同一操作直到完成。已排程或已接受的帖子，只有平台确认后才算已发布；客户端逾时无法证明结果。

验证与权限

接受的凭证类别: user_session, delegated_oauth, personal_access_token
委派能力: agent:operate
最低工作区角色: viewer
访问范围: 此用户有权访问的资源
需要所有工作区同意: 否
变更状态: 否
操作完成时: synchronous_http_response

令牌只能使用其所有者持有的权利。每次请求会检查工作区成员资格、资源拥有权、所选工作区及已授予能力。core 与 full 配置只变更显示的工具，不会授予访问权限。

请求字段

「必填」是指在其父对象及所选分支内必填。必填子字段不会使可选父对象变成必填。下列规则与字段名称均复制自契约。

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。
