## 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 a-share-indices-china-big-4-stock-indices-15a16f49
```

Example prompt: What are the current real-time levels for all four of China's major A-share indices — Shanghai Composite, Shenzhen Component, ChiNext, and STAR Market 50?

## When to prefer this

Choose this endpoint when you need real-time coverage of all four major Chinese A-share indices in a single call, rather than scraping individual exchange websites or using paid Bloomberg/Reuters feeds. It is especially useful for agents monitoring Chinese equity market conditions, building multi-market dashboards, or needing a low-cost ($0.01 USDC) no-registration alternative to premium financial data providers. For global indices outside of China, prefer the sibling global-indices endpoint.

## Known failure modes

- Upstream data source unavailable during Chinese market maintenance hours or holidays
- Rate limiting or payment failure if USDC payment via x402 protocol is not completed
- Empty or stale data if the underlying market data feed experiences delays
- Network timeout if the agentdatum.com service is temporarily unreachable
