How this service works
For an investment theme (e.g. HBM, 유리기판, 원전, robotics), the Korean listed companies linked to it with evidence graded confirmed / circumstantial / expectation: DART filing snippets with receipt numbers, regional revenue, earnings and order headlines, and price context since the signal. Separates real revenue from theme hype.
Output
A JSON response containing the queried theme name and an array of matched KRX-listed companies, each with: company code and name, an evidence grade (confirmed/circumstantial/expectation in Korean: 확인/정황/기대), DART regulatory filing snippets with receipt numbers, earnings and order-related headlines, and price context since the theme signal emerged. This separates companies with real revenue from those only speculatively associated with the theme.
Example use cases
Separating real HBM plays from hype
“Find me the top 8 Korean stocks linked to the HBM theme and tell me which ones have confirmed revenue in their DART filings versus which are just riding the hype — I want the evidence grade for each.”
Researching 유리기판 glass substrate theme
“Which KRX-listed companies have actual exposure to the 유리기판 (glass substrate) theme? Show me up to 12 companies with their evidence grade and any DART filing snippets you can find.”
Nuclear power theme stock screening
“I'm looking at the 원전 (nuclear power) investment theme in Korea — which listed companies have confirmed or circumstantial links to it with earnings headlines, and what's the price context since the theme emerged?”

Endpoint
GEThttps://x402.deepsearch.com/v1/context/theme-evidence?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to evaluate Korean KRX-listed stocks by their actual, evidenced connection to a specific investment theme — particularly when distinguishing confirmed DART-filing revenue from speculative thematic association. Prefer this over generic stock screeners or news endpoints when thematic evidence grading and regulatory filing snippets are needed. Ideal for investment research workflows focused on Korean equity markets and named investment themes like HBM, 유리기판, 원전, or robotics.
Side effects
- Unknown or misspelled theme keyword returns empty company array

- Theme with no DART filing evidence returns companies with only expectation-grade entries
- Non-Korean themes may have limited or no KRX company matches
- Network or payment (x402) failure returns no data
