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 with ok:true, a date field, sort method used, market filter, total matching records count, and an items array where each element contains: stock code, name, board, symbol, close price, percent change, margin buy amount, margin repay amount, margin net buy, 5-day and 10-day net buy, short balance, short volume, margin balance, margin balance 5-day and 10-day percent change, and margin-to-market-cap ratio. Also includes aggregate totals for margin net buy and balance across returned items, and a source attribution string.
Example use cases
Daily margin flow leaderboard
“Give me today's top 50 A-share stocks ranked by margin net buy amount — I want to see which ones are seeing the most margin money flow in right now across both markets.”
Single-stock margin history
“Show me the historical margin trading data for Kweichow Moutai (stock code 600519) — I want to track how its margin balance and short position have changed over recent trading days.”
Shenzhen market margin ratio screen
“Fetch margin trading data for the Shenzhen market (sz), sorted by margin-to-market-cap ratio (ratio), and return the top 100 stocks — I want to find which Shenzhen stocks are most heavily leveraged relative to their float.”

Endpoint
GEThttps://cn-data-x402.cn-data-x402-worker.workers.dev/cn/margin?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, machine-readable Chinese A-share margin trading (融资融券) data that is otherwise only available as web pages or proprietary data terminals. It is ideal for agents that need daily margin flow rankings, stock-level margin balance history, or short position screening across Shanghai and Shenzhen markets without requiring an API key or subscription — just a $0.02 USDC micropayment per call via the x402 protocol.
Side effects
- HTTP 402 returned before payment — must pay $0.02 USDC on Base and retry
- Invalid date (non-trading day or future date) may return empty items array
- Invalid symbol (non-existent stock code) returns empty or single-item result
- Invalid sort value or market value may result in default fallback or error
- limit out of range (outside 1-300) may cause validation error
- Network timeout from upstream Eastmoney data source
