}Examples illustrate the response structure. Actual results depend on the API response.
- Authentication
- Send X-API-Key in request headers
- Rate limit
- 60 req/min
- Timeout
- 10000 ms
Send your API Key in the X-API-Key header from your backend.
Check both HTTP status and business fields before treating a call as successful.
Use retries and backoff together with rate limits in high-frequency scenarios.
Request Fields
Send requests from your server with the key in the X-API-Key header.

Capabilities, use cases, limitations, and frequently asked questions.
接口能力
使用本服务内的 HanLP TextRank 算法,从文本中提取关键词,返回按相关性排序的字符串列表。不调用第三方供应商或大模型。
请求参数
- text:必填非空字符串,最长 20000 个 UTF-16 字符单元。
- num:可选整数,范围 1–50,默认 10;兼容工具提交的字符串数字。
返回结果
data.list 为关键词字符串数组。实际关键词不足 num 时返回实际数量;没有有效候选词时返回空数组。请求无效时返回 INVALID_PARAM。
使用边界
适用于中文和中英混排的一般文本;纯英文及专业领域的效果需按业务语料评估。不保证与原第三方接口相同的词汇或排序,也不提供语义生成、关键词翻译或行业准确率承诺。
