convertible_bond
Query convertible bond non-market data including issuance details by date range or specific bond information by code.
Instructions
获取可转债非行情数据，支持两种查询方式：1)使用issue类型按时间范围查询可转债发行数据；2)使用info类型按代码查询可转债详细信息
Input Schema
TableJSON Schema
| Name | Required | Description | Default |
|---|---|---|---|
| ts_code | No | 可转债代码，如'110001.SH'表示国电转债，'128001.SZ'表示平安转债。配合info类型使用可查询详细信息 | |
| data_type | Yes | 数据类型，可选值：issue(可转债发行数据)、info(可转债详细信息，通过代码查询) | |
| start_date | No | 起始日期，格式为YYYYMMDD，如'20230101'。用于查询发行数据的公告日期范围 | |
| end_date | No | 结束日期，格式为YYYYMMDD，如'20230131'。用于查询发行数据的公告日期范围 |
Implementation Reference
- src/tools/convertibleBond.ts:3-105 (handler)Core tool definition including handler (run function), schema (parameters), name, and description. The run method fetches convertible bond data (basic/issue/info) from Tushare API, handles errors, and formats output as formatted text.
