# CN Data – Chinese IPO Filing Pipeline

> CN Data – Chinese IPO Filing Pipeline is a paid API for AI agents from cn-data-x402.cn-data-x402-worker.workers.dev, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-16).

Returns structured JSON data on Chinese IPO applications filed with A-share regulators, filterable by board, state, industry, and recency.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability cn-data-chinese-ipo-filing-pipeline-983cf6fe
```

Example prompt: Pull the latest Chinese IPO filing pipeline — give me all companies currently in 已问询 (under inquiry) status on the 科创板 from the past 90 days, up to 100 results, and group them by board.

## When to prefer this

Choose this endpoint when you need machine-readable Chinese A-share IPO pipeline data — including filing status, sponsor identity, industry, and board breakdown — without needing a registered API key. Ideal for agents monitoring the Chinese IPO regulatory queue, doing competitive intelligence on sectors, or checking the status of a specific company. It is especially useful when the source data is only available in Chinese web pages, since this endpoint normalises them to clean JSON.

## Known failure modes

- HTTP 402 returned on first call — agent must pay $0.02 USDC on Base and retry
- Invalid or non-existent 6-digit symbol returns empty items array
- Unsupported `state` or `board` string (non-enum value) may return zero results rather than an error
- `limit` outside 1-300 range may be rejected or clamped
- Network timeout from upstream East Money data source causing delayed or failed response

## 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` and a `data` object containing: an `items` array of IPO filings (each with code, name, board, state, region, sponsor, law firm, accounting firm, acceptDate, updateDate, registrationStatus), aggregate breakdowns by board and by state, applied filter echoes, total matching count, and a source attribution string crediting East Money's public API.
