How this service works
Korean (KRX) stock data for AI agents: analyst consensus, investor flows, market pulse, knowledge-graph signals (why a stock moved, hot themes, theme revenue evidence), 10-year financials and 3-year prices, plus US fundamentals and SEC filings. Pay per call in USDC on Base Mainnet — no subscription, no API key.
Output
Returns a JSON object containing the stock's closing price, ticker symbol, exchange, company name (may be in Korean), and market capitalization in USD. Example: {close: 327.5, ticker: 'AAPL', exchange: 'NASDAQ', companyName: '애플', marketCapUSD: 4901758191440}.
Example use cases
Portfolio snapshot for US holdings
“Pull the latest closing price and market cap for AAPL, NVDA, and TSM — I want a quick snapshot of my US equity positions.”
Research screen for a NASDAQ stock
“I'm researching NVIDIA before an earnings call — can you grab the latest price and market cap from DeepSearch for NVDA on NASDAQ?”
Competitive market cap comparison
“Get me the current market cap and closing price for both MSFT and GOOGL so I can compare their valuations side by side.”
Technical details
Endpoint
GEThttps://x402.deepsearch.com/v1/context/us/company/%7Bticker%7D?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need quick pay-per-query access to US stock price and market cap data without a subscription, especially when integrating with crypto-native payment workflows on Base Mainnet. Prefer it over subscription APIs for low-frequency, ad-hoc lookups of NASDAQ or NYSE stocks by ticker symbol.
Side effects
- Invalid or unrecognized ticker symbol returns an error or empty result
- Exchange parameter mismatch (e.g. NYSE ticker queried as NASDAQ) may return no data
- Payment failure (insufficient USDC on Base Mainnet) blocks the request
- Rate or quota issues may return 402 Payment Required
- Delisted or OTC stocks may not be found in the dataset
