## 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 cn-data-chinese-stock-quotes-8f7de22e
```

Example prompt: What's the current stock price, daily change, and volume for Kweichow Moutai (600519) and Tencent (00700.HK)?

## When to prefer this

Use this endpoint when you need structured, machine-readable stock quote data for Chinese A-shares (Shanghai/Shenzhen) or Hong Kong-listed equities without needing an API key or account. It is ideal for agents that require on-demand, pay-per-call access to Chinese market data via the x402 micropayment protocol, especially when querying up to 5 symbols at a time. Prefer this over scraping Chinese financial web pages or setting up authenticated brokerage API accounts.

## Known failure modes

- Invalid or unrecognized symbol returns the ticker in the 'failed' array with partial:true
- More than 5 symbols provided may be rejected or truncated
- Payment not completed results in HTTP 402 with payment terms; data not returned until USDC payment on Base is confirmed
- Exchange or data source unavailable may result in empty quotes array
- Malformed symbol format (e.g. missing exchange prefix where required) may cause lookup failure

## How this service works

Chinese market and China-focused public data over the x402 protocol. No API key and no signup: call any endpoint, receive HTTP 402 with payment terms, pay the listed amount in USDC on Base and retry. Every response is JSON. Some Chinese-language sources are published only as web pages — these endpoints return them as clean, machine-readable JSON.

## Output

A JSON object with an array of stock quotes, each including the stock name, current price, price change, percentage change, day high/low, volume, currency (CNY or HKD), exchange name, market state (OPEN/CLOSED), previous close, and UTC market timestamp. Also includes a list of any failed symbols and a partial flag if some lookups succeeded.
