+short_description: "Quake网络空间搜索接口，支持自定义query、size、fields"
+description: |
+  Quake（360 网络空间测绘）资产搜索工具，调用 Quake API v3 实时检索互联网资产。
+
+  **主要功能：**
+  - 支持 Quake DSL 查询语法（query）
+  - 支持返回数量控制（size）
+  - 支持字段裁剪（fields，对应 Quake include）
+  - 支持分页偏移（start）
+
+  **鉴权方式：**
+  - Header 使用 `X-QuakeToken`
+  - 可在本文件中填写 `QUAKE_API_KEY`，或通过环境变量 `QUAKE_API_KEY` 注入
+
+  **常见查询示例：**
+  - `domain:"example.com"`
+  - `ip:"1.1.1.1"`
+  - `port:443`
+  - `service.name:"http" AND country_cn:"中国"`
+
+  **注意事项：**
+  - API 调用会消耗积分，请按需控制 `size`
+  - `fields` 会映射到请求体 `include` 字段，多个字段用英文逗号分隔
+  - 如遇语法报错，请先在 Quake 控制台验证 DSL

+short_description: "Shodan网络空间搜索，支持search与count模式"
+description: |
+  Shodan 资产搜索工具，基于官方 Developer API 实现，支持快速检索和统计分析。
+
+  **主要功能：**
+  - 使用 `/shodan/host/search` 进行资产搜索
+  - 使用 `/shodan/host/count` 进行无明细统计（节省查询信用）
+  - 支持按 `size` 控制返回条数（自动翻页聚合）
+  - 支持分页（page）
+  - 支持分面统计（facets）
+  - 支持结果字段裁剪（fields）
+  - 支持 `minify` 控制返回数据体积
+
+  **鉴权方式：**
+  - Query 参数使用 `key`
+  - 可在本文件中填写 `SHODAN_API_KEY`，或通过环境变量 `SHODAN_API_KEY` 注入
+
+  **查询语法示例：**
+  - `product:nginx`
+  - `apache country:DE`
+  - `port:22`
+  - `org:"Amazon" port:443`
+  - `ssl.cert.subject.cn:example.com`
+
+  **注意事项：**
+  - 带过滤器的查询通常会消耗 query credits
+  - 翻页（超过第1页）会额外消耗额度
+  - `size` 大于 100 时会自动请求更多页（每页最多 100）
+  - `size` 最大限制为 1000（防止过量请求）
+  - `count_only=true` 使用统计接口，不返回 matches 明细
+parameters:
+  - name: "query"
+    type: "string"
+    description: |
+      Shodan 搜索语句（必需）。
+
+      支持 Shodan filter 语法（`filter:value`）与关键字组合。
+      示例：
+      - `product:nginx`
+      - `apache country:DE`
+      - `port:22`
+      - `org:"Amazon" port:443`

+    format: "positional"
+  - name: "count_only"
+    type: "bool"
+    description: |
+      是否仅统计总数（可选）。
+
+      - `false`（默认）：调用 `/shodan/host/search` 返回明细

+      - 支持 `10 / 20 / 100 / n`
+      - Shodan 单页最多 100，超过 100 时会自动翻页拼接
+      - 为避免额度和时延问题，最大值限制为 1000
+      - 未传时默认返回单页结果（最多 100 条）
