## 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 claw402-china-stock-basic-info-api-cba69a46
```

Example prompt: Can you get me a list of all currently listed Chinese A-shares on the Shanghai exchange? I want the basic stock info including codes and names.

## When to prefer this

Use this endpoint when you need basic reference data for Chinese A-share stocks, particularly when you need to filter by exchange (Shanghai/Shenzhen), listing status (listed/delisted/suspended), or HS connectivity. Prefer this over general market data APIs when you specifically need Chinese equity listings without requiring API keys or registration — just a USDC wallet.

## Known failure modes

- Empty data array returned if no stocks match the given filters
- Invalid exchange or list_status parameter values may return error code
- Payment failure via x402 protocol returns HTTP 402 if USDC wallet balance is insufficient
- Network timeout if vergex.trade backend is unavailable
- Malformed query parameters may result in a non-zero error code in the response

## How this service works

Backed by vergex.trade. Pay for any API with USDC. No API keys. No registration. Just a wallet.

## Output

Returns a JSON object with a code field (0 for success) and a data array containing basic stock information for Chinese equities matching the query filters — typically including stock codes, company names, exchange, and listing status.
