## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability deepsearch-us-stock-intelligence-api-7b185d84
```

Example prompt: Pull up NVDA's stock data from DeepSearch — I need the daily price history and financials for it on NASDAQ.

## When to prefer this

Choose this endpoint when you need historical daily price data or multi-year financial history for US-listed stocks (NASDAQ or NYSE), especially when you want pay-per-query access without a subscription. Ideal for agents performing one-off financial lookups, research tasks, or building lightweight stock analysis workflows with USDC micropayments on Base Mainnet.

## Known failure modes

- Invalid or unknown ticker symbol returns an error or empty result
- Missing required ticker query parameter causes a 400 bad request
- Payment failure or insufficient USDC balance blocks the request via x402 protocol
- Unsupported exchange value may cause a lookup failure
- Rate limits or network errors may cause intermittent failures

## 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 JSON object with the stock's closing price, date, ticker symbol, and exchange name. May also include up to 3 years of daily price history and up to 10 years of financial data depending on availability for the requested ticker.
