What it does

Historical daily, weekly or monthly candlesticks (K线) for A-shares, Hong Kong stocks, US stocks and Chinese indices, straight from a Chinese quote feed: each bar carries date, open, high, low, close, volume and its change percent versus the previous bar. Ships what a raw feed does not — moving averages (MA5/MA10/MA20/MA60) computed over the returned window, the window's own high/low and start-to-end change, the latest live quote with name and previous close, and volumes normalised to shares (A-share and index feeds quote lots of 100). Pass ?symbol=600519 / sh600519 / 000001.SZ / 00700.HK / AAPL / sh000300, ?days=2-500 (default 60), ?period=day|week|month and ?adj=qfq|hfq|none (default 前复权 qfq). Chinese data vendors gate historical candles behind paid SDKs and most English APIs simply do not carry A-share adjustment factors. 中文:历史K线——日/周/月线 OHLCV + 均线 + 区间统计,支持 A股、港股、美股和指数,默认前复权。 No API key and no signup: call the endpoint, it answers HTTP 402 with the payment terms, pay per request in USDC on Base with any x402-compatible client or wallet, then retry the same request to get the data.

Use with an agent

  1. Discover. Agents find this listing with GET https://bazaar.saylorinnovations.com/discovery/search?query=…, the MCP tool search_resources, or /discovery/resources.
  2. Inspect. Fetch /resources/74992.json for the price and payment options.
  3. Pay. Call GET https://cn-data-x402.cn-data-x402-worker.workers.dev/cn/kline. The provider answers 402 with its payment requirements. An x402 client signs one of the options below and retries with PAYMENT-SIGNATURE.
  4. Execute. The provider returns 200 with the data. Agent Bazaar is not in the request path and never sees your payment.

For humans

You don't need an account or an API key; you need a wallet holding a small amount of USDC on Base, and an x402-capable client (see the examples below). Call the endpoint unpaid first to see exactly what it asks for.
