## 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-index-quotes-6efd5d61
```

Example prompt: What is the Shanghai Composite (上证指数) index trading at right now? Pull the latest quote including price, change, and percent change.

## When to prefer this

Choose this endpoint when you need machine-readable, real-time Chinese stock index quotes (especially Shanghai/Shenzhen) without an API key or subscription — particularly useful when building agents that need pay-per-use access to China market data, or when Chinese-language financial web pages need to be consumed as structured JSON.

## Known failure modes

- HTTP 402 returned before payment is made — agent must pay USDC on Base and retry
- Empty quotes array if all symbols fail to resolve
- Partial results with some entries in the failed array if individual index feeds are unavailable
- Network timeout from the Cloudflare Worker edge if upstream data source is slow

## 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 ok:true and a data object containing a quotes array. Each quote has name (Chinese index name), symbol (e.g. 000001.SS), price, change, changePercent, previousClose, and currency (CNY). A failed array lists any symbols that could not be fetched.
