Implementation Reference
- server/index.js:262-315 (handler)The main handler function that fetches Near Earth Object (NEO) feed data from NASA's API based on provided date range, processes the asteroids data, and returns a formatted text response listing up to 10 NEOs with details like name, size, hazard status, and approach data.
async getNEOFeed(args) { const { start_date, end_date } = args || {}; const params = new URLSearchParams({ api_key: this.apiKey, }); if (start_date) params.append('start_date', start_date); if (end_date) params.append('end_date', end_date); const response = await fetch(`${this.baseUrl}/neo/rest/v1/feed?${params}`); const data = await response.json(); if (!response.ok) { throw new Error(`NASA API 오류: ${data.error?.message || '알 수 없는 오류'}`); } const totalCount = data.element_count; const dates = Object.keys(data.near_earth_objects); let neoList = []; dates.forEach(date => { data.near_earth_objects[date].forEach(neo => { neoList.push({ date, name: neo.name, id: neo.id, diameter: neo.estimated_diameter.kilometers, hazardous: neo.is_potentially_hazardous_asteroid, close_approach: neo.close_approach_data[0], }); }); }); return { content: [ { type: 'text', text: `**근지구 천체 정보** (${start_date || '오늘'} ~ ${end_date || '7일 후'}) 총 ${totalCount}개의 근지구 천체가 발견되었습니다: ${neoList.slice(0, 10).map((neo, index) => ` ${index + 1}. **${neo.name}** - **ID**: ${neo.id} - **날짜**: ${neo.date} - **지름**: ${neo.diameter.estimated_diameter_min.toFixed(3)} - ${neo.diameter.estimated_diameter_max.toFixed(3)} km - **위험 여부**: ${neo.hazardous ?
