## 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 hermes-data-api-china-a-share-stock-price-a331537c -d '<json body>'
```

Example prompt: Can you get me the current stock price for Kweichow Moutai (code 600519) on the China A-share market?

## When to prefer this

Choose this endpoint when you need real-time or intraday price data specifically for China A-share equities listed on the Shanghai or Shenzhen exchanges. It is the right choice when you have a valid A-share stock code (e.g. 600519, 002594) and need structured quote data including open, high, low, and previous close. Prefer it over crypto or forex endpoints on the same service for equity-specific queries.

## Known failure modes

- Invalid or unrecognized stock code returns an error or empty response
- Non-A-share tickers (e.g. US stocks or crypto symbols) are not supported by this endpoint
- Payment failure via x402/USDC results in HTTP 402 and no data returned
- Market closed hours may return stale or last-close prices rather than live quotes
- Network timeout or Sina upstream outage results in a service error

## How this service works

Pay-per-call data API: crypto prices (CoinGecko), China A-share quotes (Sina), weather (Open-Meteo), forex rates, and Ethereum gas fees. Payments via x402 protocol, USDC on Base.

## Output

A JSON object containing the stock's current price, open, high, low, previous close, stock name (in Chinese), stock code, Unix timestamp in milliseconds, and data source identifier ('sina').
