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.
Example use cases
Daily A-share momentum briefing
“Give me today's China limit-up stocks ranked by consecutive boards — top 30 — so I can see which ones are on multi-day runs and what industries they're in.”
Sector rotation analysis on specific date
“Fetch the limit-up pool for October 8, 2026, sorted by seal fund amount, and tell me which industries have the most stocks hitting the ceiling that day.”
Early-seal momentum screening
“Get today's Chinese limit-up stocks sorted by first seal time so I can see which ones locked up at the open — limit to 50 results.”
Technical details
Endpoint
GEThttps://cn-data-x402.cn-data-x402-worker.workers.dev/cn/limit-up?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
