## 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-china-market-brief-8933d71c
```

Example prompt: Can you check if the Chinese stock market is open right now and give me the latest USD to CNY and EUR to CNY exchange rates, plus whether today is a public holiday in China?

## When to prefer this

Choose this endpoint when you need a quick, all-in-one China market status check combining FX rates, trading session status, and holiday calendar in a single call. Ideal for agents that need to gate China-related financial operations on market availability or check CNY rates before cross-border payments, without needing a full financial data subscription or API key.

## Known failure modes

- HTTP 402 returned on first call — agent must pay listed USDC amount on Base and retry
- Stale or unavailable upstream market data may return outdated session status
- Holiday calendar may not reflect last-minute government schedule changes
- Network timeout on the Cloudflare Worker edge node

## 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 three sections: fx (CNY exchange rates for EUR and USD), market (session open/closed status, current Beijing timestamp, boolean trading flag), and holiday (today's date, holiday name in Chinese, boolean isHoliday flag). Wrapped in a standard {ok, data, endpoint} envelope.
