-## 7. 访问导出媒体
+## 7. 朋友圈接口
+
+### 7.1 获取朋友圈时间线
+
+```http
+GET /api/v1/sns/timeline
+```
+
+参数：
+
+| 参数 | 类型 | 必填 | 说明 |
+| --- | --- | --- | --- |
+| `limit` | number | 否 | 返回数量，默认 20，范围 `1~200` |
+| `offset` | number | 否 | 偏移量，默认 0 |
+| `usernames` | string | 否 | 发布者过滤，逗号分隔，如 `wxid_a,wxid_b` |
+| `keyword` | string | 否 | 关键词过滤（正文） |
+| `start` | string | 否 | 开始时间，支持 `YYYYMMDD` 或秒/毫秒时间戳 |
+| `end` | string | 否 | 结束时间，支持 `YYYYMMDD` 或秒/毫秒时间戳 |
+| `media` | number | 否 | 是否返回可直接访问的媒体地址，默认 `1` |
+| `replace` | number | 否 | `media=1` 时，是否用解析地址覆盖 `media.url/thumb`，默认 `1` |
+| `inline` | number | 否 | `media=1` 时，是否内联返回 `data:` URL，默认 `0` |
+
+示例：
+
+```bash
+curl "http://127.0.0.1:5031/api/v1/sns/timeline?limit=5"
+curl "http://127.0.0.1:5031/api/v1/sns/timeline?usernames=wxid_a,wxid_b&keyword=旅行"
+curl "http://127.0.0.1:5031/api/v1/sns/timeline?limit=3&media=1&replace=1"
+curl "http://127.0.0.1:5031/api/v1/sns/timeline?limit=3&media=1&inline=1"
+```
+
+媒体字段说明（`media=1`）：
+
+- `media[].url/thumb`：你应该优先直接使用的字段。
+- `replace=1`（默认）时，`media[].url/thumb` 会直接被替换成可访问地址，等价于 `resolvedUrl/resolvedThumbUrl`。
+- `replace=0` 时，`media[].url/thumb` 仍保留微信原始地址；这时再结合下面的 `raw/proxy/resolved` 字段自己决定用哪一个。
+- `media[].rawUrl/rawThumb`：原始朋友圈地址
+- `media[].proxyUrl/proxyThumbUrl`：可直接访问的代理地址
+- `media[].resolvedUrl/resolvedThumbUrl`：最终可用地址（`inline=1` 时可能是 `data:` URL）
+- `media[].token/key/encIdx`：微信源数据里的访问/解密参数。通常不需要你自己处理；如果你手动调用 `/api/v1/sns/media/proxy`，把当前条目的 `url` 和 `key` 原样传回即可。
+- `media[].livePhoto`：实况图的视频部分。外层 `media[].url/thumb` 仍是封面图，`livePhoto` 内部会再提供一组自己的 `url/thumb/raw*/proxy*/resolved*` 字段。
+- `media=0` 时，不会补充 `raw*/proxy*/resolved*`，接口只返回原始 `url/thumb` 以及源字段（如 `key/token/encIdx`）。

+
+### 7.4 朋友圈媒体代理
+
+```http

+
+参数：
+
+| 参数 | 类型 | 必填 | 说明 |

+目标：
+- 精准完成用户在聊天数据上的查询、总结、分析、回忆任务。
+- 优先使用本地工具获取证据，禁止猜测或捏造。
+- 默认输出简洁中文，先给结论，再给关键依据。
+
+工作原则：
+- Token 节约优先：默认只请求必要字段，只有用户明确需要或证据不足时再升级 detailLevel。
+- 先范围后细节：优先定位会话/时间范围，再拉取具体时间轴或消息。
+- 可解释性：最终结论尽量附带来源范围与统计口径。
+- 语音消息不能臆测：必须先拿语音 ID，再点名转写，再总结。
+- 联系人排行题（“谁聊得最多/最常联系”）命中 ai_query_top_contacts 后，必须直接给出“前N名+消息数”。
+- 除非用户明确要求，联系人排行默认不包含群聊和公众号。
+- 用户提到“最近/近期/lately/recent”但未给时间窗时，默认按近30天口径统计并写明口径。
+- 用户提到联系人简称（如“lr”）时，先把它当联系人缩写处理，优先命中个人会话，不要默认落到群聊。
+- 用户问“我和X聊了什么”时必须交付“主题总结”，不要贴原始逐条聊天流水。
+
+Agent执行要求：
+- 用户输入直接进入推理，本地不做关键词分流，你自主决定工具计划。
+- 当用户说“今天凌晨/昨晚/某段时间的聊天”，优先调用 ai_query_time_window_activity。
+- 拿到活跃会话后，调用 ai_query_session_glimpse 对多个会话逐个抽样阅读，不要只读一个会话就停止。
+- 如果初步探索后用户目标仍模糊，主动提出 1 个关键澄清问题继续多轮对话。
+- 仅当你确认任务完成时，输出结束标记 `[[WF_DONE]]`，并紧跟 `<final_answer>...</final_answer>`。
+- 若还未完成，不要输出结束标记，继续调用工具。
+
+语音处理硬规则：
+- 当用户涉及“语音内容”时，先调用 ai_list_voice_messages。
+- 让系统返回候选 ID 后，再调用 ai_transcribe_voice_messages 指定 ID。
+- 未转写成功的语音不可作为事实依据。
