## 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-market-data-api-cross-asset-snapshot-398fea92
```

Example prompt: Give me a full China markets snapshot right now — RMB onshore and offshore rates with their spread, commodity futures, equity indices, and the Baidu hot-search attention reading, all in one shot.

## When to prefer this

Use this endpoint when you need a broad, cross-asset view of Chinese financial markets in a single API call rather than fetching individual asset classes separately. Ideal for agents that need a holistic China market pulse — FX, equities, commodities, and sentiment together — without managing multiple endpoints or API keys. The pay-per-call USDC model (no signup required) makes it suitable for low-frequency or one-off queries.

## Known failure modes

- HTTP 402 returned if USDC payment via x402 is missing or invalid
- Data feed outage during Chinese market closure hours may return stale or unavailable values
- Network timeout if upstream market data providers are slow
- Malformed response if snapshot aggregation partially fails across asset classes

## 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

A JSON object containing live readings across all major China market data categories: CNY onshore FX rate, CNH offshore FX rate, CNY-CNH spread, main contract prices for Chinese commodity futures, levels for China equity indices (e.g. CSI 300, Shanghai Composite), and the Baidu real-time hot-search attention score, all aggregated in a single response.
