How this service works
Up to 10 years of financials + 3 years of daily price history for all 2,000+ KRX stocks. Pay-per-query with USDC on Base Mainnet — no subscription.
Output
Returns a list of matching ETFs with their Korean names, issuer (asset management company), and KRX ticker symbols, along with the echoed search keyword.
Example use cases
Finding semiconductor ETFs on KRX
“Can you look up all Korean ETFs related to semiconductors? I want to see their names, issuers, and symbols listed on the KRX.”
Discovering US index-tracking Korean ETFs
“Search for Korean ETFs that track the S&P500 — I want to know which ones are available on KRX and who issues them.”
Researching AI-themed Korean ETF options
“What Korean ETFs are focused on AI or artificial intelligence? Give me a list with their ticker symbols and asset managers.”
Technical details
Endpoint
GEThttps://x402.deepsearch.com/v1/context/etf/searchWhen to prefer
Use this endpoint when you need to discover or search for Korean ETFs (listed on KRX) by theme, name, or underlying holding. Ideal for investment research workflows that need to map investment themes (e.g. 반도체, AI, S&P500) to actual tradable ETF symbols in Korea. Not suitable for US-listed ETFs or for retrieving price/financial data (use sibling endpoints for that).
Side effects
- No ETFs found for obscure or misspelled keywords — returns empty etfs array
- Payment failure if USDC balance on Base Mainnet is insufficient — HTTP 402 error
- Invalid or missing keyword parameter — HTTP 400 validation error
- Rate limiting or service unavailability — HTTP 5xx error
