模块4：API与仪表板
REST API

@app.get("/api/report/weekly")
def get_weekly_report():
"""
获取最新周报
"""
report = ReportGenerator().generate_weekly_report()
return {"report": report}
可视化仪表板
使用React + ECharts构建交互式仪表板：
import React, { useEffect, useState } from 'react';
import ReactECharts from 'echarts-for-react';
function TrendChart({ keyword }) {
const [data, setData] = useState(null);
useEffect(() => {
fetch(`/api/trends/${keyword}?days=30`)
.then(res => res.json())
.then(data => setData(data));
}, [keyword]);
if (!data) return <div>加载中...</div>;
const option = {
title: { text: `${keyword} 趋势分析` },
xAxis: { type: 'category', data: data.dates },
yAxis: { type: 'value' },
series: [{
data: data.mentions,
type: 'line',
smooth: true
}]
};
return <ReactECharts option={option} />;
}

成本与扩展性
成本估算（月1000次竞品监控）
- SERP API：1000次 × $0.002 = $2
- Reader API：500次 × $0.001 = $0.5
- LLM（摘要生成）：$50
- 服务器：$100
- 总计：约$150/月
相比传统人工市场研究（$5,000-$10,000/月），节省97%。
扩展性
- 横向扩展：增加Celery worker处理更多任务
- 数据分片：按竞品或地区分片存储
- 缓存层：Redis缓存热点查询
- CDN：静态报告通过CDN分发
完整的技术实现参考金融情报自动化案例和SearchCans API文档。
总结
构建AI驱动的市场情报平台，核心要素是：
- 持续数据采集：SERP API + Reader API
- 智能分析：实体识别、情感分析、趋势检测
- 实时告警：规则引擎+异常检测
- 可视化展示：仪表板+自动报告
通过自动化，企业能从"事后分析"转向"实时监控"，从"被动应对"转向"主动决策"，在快速变化的市场中保持竞争优势。
