Capabilities

Tools 4

get_earnings_calendar

List upcoming US earnings reports for a date range (up to 14 days, US Eastern dates), largest and most-watched companies first. Optional group: bigtech, semiconductors, software, memory, healthcare, space. Use for "이번 주 실적 발표 일정", "다음 주 빅테크 실적 언제야?", "Which chip stocks report next week?". Defaults to the next 7 days. The result is shown as a calendar card.

Discovered
get_earnings_call_summary

Summarize what management said on a US company's latest earnings call or release: one-line takeaway, positives, concerns, and up to three quotes (Korean translation with the English original). Use for "아마존 어닝콜 핵심만 알려줘", "What did Nvidia's CEO say last quarter?". Available for about 220 major companies.

Discovered
get_earnings_reactions

Show how a US stock moved the day after each of its recent earnings reports (up to the 12 most recent), whether EPS beat or missed estimates, and its next earnings date in Korea and US Eastern time. Use for questions like "엔비디아 실적 발표 언제야?", "마이크로소프트 실적 나오면 주가 어떻게 움직였어?", "Does Tesla usually drop after earnings?". Historical data only; it does not predict prices. The result is shown as an interactive card with the chart, stats, and earnings-call takeaways.

Discovered
search_stocks

Find US-listed stocks by ticker or company name, including Korean names and nicknames (e.g. 구글 → GOOGL, 엔비디아 → NVDA). Use when the user names a company and you need its ticker.
