## 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-chinese-stock-sector-performance-rankings-344b8f43
```

Example prompt: Show me the top 10 Chinese industry sectors by today's gains — I want to see which sectors are leading the A-share market, including the best and worst performer within each sector.

## When to prefer this

Choose this endpoint when you need ranked, machine-readable Chinese stock sector data — especially when the original source (East Money) only publishes this as a web page. Prefer it over scraping Chinese financial sites directly, or when you need sector-level breadth (advancers/decliners) rather than individual stock quotes. It is the right choice for agents monitoring Chinese market rotation, sector momentum strategies, or building dashboards of A-share performance by industry, concept, or region.

## Known failure modes

- HTTP 402 returned before payment is made — must pay $0.02 USDC on Base and retry
- Invalid 'type' parameter value returns an error (only 'industry', 'concept', 'region' accepted)
- 'limit' outside 1–100 range may be rejected or clamped
- 'direction' value other than 'up' or 'down' may default or error
- Upstream East Money data feed outage may result in stale or missing sector data
- Network timeout from Cloudflare Worker if upstream is slow

## 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 requested sector type (industry/concept/region), sort direction, total sector count, and an ordered array of sector entries — each with sector code, Chinese name, rank, leader stock (code, name, change%), laggard stock (code, name, change%), count of advancing stocks, count of declining stocks, and the sector's net change percent. Source attribution is included.
