## 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 china-equity-indices-810efcb1
```

Example prompt: What are the current levels of the major Chinese equity indices — CSI 300, Shanghai Composite, and Hang Seng — right now?

## When to prefer this

Choose this endpoint when you need real-time Chinese equity index levels without going through a brokerage API, exchange data subscription, or Bloomberg terminal. Ideal for AI agents that need instant, no-signup access to China market benchmarks paid for via USDC micropayments (x402). Prefer this over general financial data APIs when the focus is specifically on China/HK equity indices and cost-per-call billing is acceptable.

## Known failure modes

- HTTP 402 if payment not provided or USDC balance insufficient
- Stale or delayed data if upstream exchange feed is lagging
- Empty or partial response if specific index data is temporarily unavailable
- 503/timeout if the Vercel serverless deployment is cold-starting or overloaded

## How this service works

China market data for AI agents, paid per call in USDC via x402 (HTTP 402). No signup, no API key. Endpoints cover RMB onshore and offshore FX with their spread, Chinese commodity futures main contracts, China equity indices, a Baidu real-time hot-search attention signal, and a one-call cross-asset snapshot. A free /v1/china/sample endpoint returns live samples of every dataset so a client can size the data before paying.

## Output

Returns a JSON object containing real-time data for major Chinese equity indices, including index name, current level, absolute and percentage change, and a timestamp. Covers benchmarks such as the CSI 300, Shanghai Composite (SSE), Shenzhen Component, and potentially the Hang Seng.
