What it does

The A-share IPO pipeline (IPO 申报排队): companies that have filed for a mainland listing, with their review status (已受理 filed / 已问询 under enquiry / 上市委会议通过 approved by the listing committee / 提交注册 filed for registration / 注册生效 registration effective / 中止 suspended / 终止 withdrawn), the board they target (北交所 / 科创板 / 创业板 / 主板), the acceptance date, latest update date, CSRC industry classification, registered address, sponsor brokerage, law firm and accounting firm. Defaults to newest filings first; filter with ?state=注册生效, ?board=科创板, ?industry=计算机, ?symbol=874673, ?days=90 (only filings accepted in the last 90 days) and ?limit=1-300. Returns board and status tallies for the returned slice. Tracking who is trying to list, on which board and with which sponsor is otherwise a paginated exchange-website chore. 中文：A股 IPO 申报排队——拟上市企业、拟上市板块、审核状态、受理日、行业、注册地、保荐机构与中介机构。 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/74994.json for the price and payment options.
3. Pay. Call GET https://cn-data-x402.cn-data-x402-worker.workers.dev/cn/ipo. 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.
