## 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 cn-data-china-a-share-limit-up-board-a87c3563
```

Example prompt: Pull today's China A-share limit-up board list, sorted by consecutive boards count, and show me the top 20 stocks with their seal fund amounts and industries.

## When to prefer this

Use this endpoint when you need structured, machine-readable A-share limit-up (涨停) data for a specific trading date without any API key or signup friction. It is ideal over scraping East Money directly because it normalizes Chinese web page data into clean JSON. Prefer it over generic financial data APIs when you specifically need consecutive board counts, seal fund amounts, and industry aggregations for Chinese A-shares.

## Known failure modes

- HTTP 402 returned before payment — caller must pay listed USDC amount on Base and retry
- Invalid date format or non-trading day returns an error or empty dataset
- limit parameter out of range (must be 1–200) may cause a validation error
- sort value other than 'boards', 'fund', or 'time' may be rejected
- Data may not yet be available if queried before market close for the current day

## How this service works

Chinese market and China-focused public data over the x402 protocol. No API key and no signup: call any endpoint, receive HTTP 402 with payment terms, pay the listed amount in USDC on Base and retry. Every response is JSON. Some Chinese-language sources are published only as web pages — these endpoints return them as clean, machine-readable JSON.

## Output

A JSON object containing: the trading date, sort method used, a ranked list of limit-up stocks (code, name, market, price, change percent, consecutive boards count, first/last seal time, seal fund in yuan, turnover percent, industry), plus aggregate stats: total limit-up count, total seal fund, max consecutive boards, earliest seal time, breakdown by industry, and breakdown by consecutive board count.
