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: an array of OHLCV bar objects (date, open, high, low, close, volume in lots, volume in shares, change percent), a moving averages object (MA5/MA10/MA20/MA60), a range summary (overall high/low/change%), the latest real-time quote (price, open, previous close), stock name and code, market identifier, period type, adjustment method, and data source attribution in Chinese.

Example use cases

Daily chart for A-share momentum strategy

“Get me the last 120 daily K-line bars for BYD (002594) with forward price adjustment so I can run a momentum backtest — I need open, high, low, close, and volume.”

Weekly trend check on CSI 300 index

“Fetch 52 weeks of weekly candlestick data for the CSI 300 index (sh000300) with no price adjustment, so I can see the year-long trend.”

Hong Kong H-share price history

“I need 60 daily OHLCV bars for Tencent (00700.HK) with backward adjustment (hfq) — can you grab that from the CN Data kline service?”

Endpoint

When to prefer

Choose this endpoint when you need structured OHLCV candlestick history for Chinese A-share, H-share, or index symbols without requiring an API key or subscription — payment is per-call in USDC via x402. Prefer it over generic global stock APIs when you specifically need Chinese market data with split-adjusted prices, Chinese-language metadata (stock names), and moving averages bundled in one call. It also handles Hong Kong and US-listed symbols with automatic exchange suffix resolution.

Side effects

Missing or invalid symbol returns an error JSON with ok:false
Symbol not found on the upstream Tencent data source returns empty bars
Requesting more bars than available history returns fewer bars than requested (returned < requested)
Unsupported adj value or period string may result in default fallback or error
HTTP 402 returned if payment has not been completed — agent must pay USDC on Base and retry
Network timeout from upstream Tencent endpoint causes delayed or failed response
