How this service works
Korean listed companies with the sharpest news surge versus their own history over the last N days (default 7), each with article count, burst ratio, net sentiment, representative headlines and same-period DART filings, plus a distress flag for halts or designation risk. by=burst (default), volume, or positive.
Output
A JSON object containing the look-back date range, the ranking method used, and an ordered list of hot companies each with: company code, name, article count, burst ratio (news volume vs own baseline), net sentiment score, representative Korean-language headlines, same-period DART regulatory filings, and a boolean distress flag indicating halt or designation risk.
Example use cases
Momentum stock screening via news burst
“Show me the top 15 Korean stocks with the biggest news burst relative to their own history over the past 14 days, ranked by burst ratio — I want to spot momentum plays before they get crowded.”
Positive news flow for long-only ideas
“Find Korean listed companies with the strongest positive news surge over the last 7 days — rank them by positive sentiment so I can identify potential long candidates.”
Distress and halt risk early warning
“Pull the hot-companies list for the last 5 days and highlight any Korean stocks that have a distress flag — I need to know which ones might be at risk of trading halts or regulatory designation.”

Endpoint
GEThttps://x402.deepsearch.com/v1/context/hot-companies?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to identify which Korean KRX-listed companies are experiencing abnormal media attention relative to their own historical baseline — particularly useful for momentum screening, early distress detection, or news-driven event analysis. Unlike generic trending endpoints, this measures burst ratio against each company's own history (not absolute volume), making it sensitive to genuine anomalies for smaller-cap names. Prefer over volume-based alternatives when you want to catch emerging stories before they become widely known.
Side effects
- Invalid 'days' value outside 1-30 range returns an error
- Invalid 'by' enum value (not burst/volume/positive) returns a validation error
- Invalid 'limit' value outside 1-30 range returns an error
- No companies meet the burst threshold for the given window — returns empty hot_companies array
- Payment failure (insufficient USDC balance) blocks the request
