## 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-a-share-daily-basic-stock-data-af70a8df
```

Example prompt: Can you pull the daily basic stock data for 000001.SZ on the Chinese A-share market for trades between 2024-01-01 and 2024-03-31?

## When to prefer this

Use this endpoint when you need daily basic fundamental metrics (P/E, turnover, market cap, etc.) for Chinese A-share listed stocks, especially when you want to avoid API key registration and prefer paying per-call in USDC via the x402 protocol. Prefer this over traditional data providers when operating in a crypto-native, wallet-based agent workflow.

## Known failure modes

- Empty data array returned if ts_code is invalid or not a Chinese A-share ticker
- Empty results if trade_date or date range has no trading activity (e.g. weekend/holiday)
- Non-zero error code if required parameters are missing or malformed
- Payment failure if USDC wallet balance is insufficient for the $0.002 fee
- No data returned for very recent dates if data pipeline has a lag

## How this service works

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

## Output
