Flight Price Advisor with Trend Chart for developer

Embed interactive flight price trend charts into AI responses. Requires SerpAPI key for real-time data. Use when users want to visualize 60-day price history for specific flight routes.

Flight Price Chart

Embed an interactive flight price trend visualization component when AI responses contain flight recommendations with confirmed OD (Origin-Destination) pairs.

⚠️ 使用前必需配置

本 skill 需要 SerpAPI Key 才能获取实时航班价格数据。

如果用户尚未配置 SerpAPI Key，请先引导用户完成以下步骤：

1. 注册 SerpAPI 账号：访问 https://serpapi.com/users/sign_up 免费注册
2. 获取 API Key：登录后在 Dashboard 中复制你的 API Key
3. 配置项目：
   • 复制 price/config.example.json 为 price/config.json
   • 将 API Key 填入 config.json 中的 serpapi.apiKey 字段
   • 重启服务器使配置生效

💡 SerpAPI 提供免费额度，足够个人使用。配置完成后即可获取真实的航班价格趋势数据。

Quick Start

1. Detect flight recommendations: When AI output contains flight search results with specific origin and destination
2. Fetch price data: Call the price trend API with the OD pair
3. Render component: Embed the PriceChart component at the end of the response

Component API

PriceChart Component

jsx

<PriceChart
  data={priceHistory}           // Array of {date, price}
  currentPrice={currentPrice}   // Current flight price
  analysis={analysis}           // Price analysis object
  destination={destination}     // Destination info
/>

Data Structure

priceHistory - 60-day price history:

javascript

[
  { date: "2026-03-01", price: 1299 },
  { date: "2026-03-02", price: 1350 },
  // ... up to 60 days
]

analysis - Price analysis object:

javascript

{
  min: 1199,           // Lowest price in period
  max: 1899,           // Highest price in period
  average: 1450,       // Average price
  pctDiff: -12,        // Percentage vs average
  level: "low",        // "low" | "mid" | "high"
  trend: "falling"     // "falling" | "rising" | "stable"
}

destination - Destination info:

javascript

{
  code: "TYO",         // Airport/city code
  name: "Tokyo"        // City name
}

Usage Scenarios

1. After Flight Search Results

When AI returns flight recommendations:

text

[Flight cards showing 3-5 options]
[Price trend chart showing 60-day history]
[Buy/wait recommendation]

2. Price Inquiry Responses

When user asks about price trends:

text

"Here's the price trend for Tokyo flights over the past 60 days..."
[Price trend chart]
"Current prices are 12% below average, making it a good time to buy."

3. Buy/Wait Recommendations

When providing purchase timing advice:

text

[Price analysis summary]
[Recommendation card: "Buy Now" or "Wait"]
[Price trend chart for context]

Integration with flyai

When using flyai for flight searches:

1. Call flyai search-flight to get flight results
2. Extract OD pair from search parameters
3. Call price trend API with OD pair
4. Append PriceChart component after flight cards

Data Source Notice

Quick Setup for Real Data

By default, the price trend uses simulated data (for demo/development only).

To enable real price data, configure your SerpAPI Key:

1. Get API Key at https://serpapi.com/users/sign_up
2. Add to price/config.json:

   json

   { "serpapi": { "apiKey": "your-key-here" } }
   

3. Restart the server

See references/configure-serpapi.md for detailed setup guide.

Data Flow

text

Before: User Query → Mock Data Generator → Estimated Prices
After:  User Query → SerpAPI → Real Prices → Auto-collect & Store

Confidence Levels

As data accumulates, AI responses should indicate confidence:

Days of Data	Confidence	AI Disclaimer
< 7 days	Low	"价格数据为估算值，仅供参考"
7-29 days	Medium	"根据部分真实价格数据..."
30+ days	High	"根据积累的真实价格数据..."

See references/data-sources.md for more details.
