## 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-1-year-stock-price-history-92e54e43
```

Example prompt: Can you pull the last 1 year of daily closing prices for Samsung Electronics — its KRX ticker is 005930 — including the daily change percentage and market cap?

## When to prefer this

Choose this endpoint when you need exactly 1 year of daily closing price history with change % and market cap for a KRX-listed Korean stock or supported US symbol, especially in a pay-per-query context where you want minimal cost ($0.15 USDC) for a focused time window rather than retrieving multi-year historical data.

## Known failure modes

- Invalid or unknown ticker returns an error or empty dataset
- Unsupported exchange code results in a lookup failure
- Missing required ticker parameter causes a 400-level validation error
- Payment failure (insufficient USDC balance) causes a 402 Payment Required response
- Rate limiting or service unavailability returns a 5xx error
