What it does

A-share block trade (大宗交易) detail for the latest trading day, or any date you pass: deal price, close price, premium or discount versus the close, traded shares, turnover in yuan, the buyer and seller brokerage seats, the stock's change percent, turnover rate and the trade's rank for that stock. Includes per-day totals and counts of premium vs discount trades. Pass ?date=YYYY-MM-DD for a past day, ?symbol=002384 for one stock, ?sort=amount|volume|premium and ?limit=1-300. Block trades often front-run or follow major position changes, and this data is otherwise only published as paginated web pages. 中文：A股大宗交易明细——成交价、折溢价率、成交量额、买卖营业部席位，默认最近一个交易日，含每日汇总。 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

Discover. Agents find this listing with GET https://bazaar.saylorinnovations.com/discovery/search?query=…, the MCP tool search_resources, or /discovery/resources.
Inspect. Fetch /resources/74987.json for the price and payment options.
Pay. Call GET https://cn-data-x402.cn-data-x402-worker.workers.dev/cn/block-trade. The provider answers 402 with its payment requirements. An x402 client signs one of the options below and retries with PAYMENT-SIGNATURE.
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.
