## 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-china-a-share-lockup-expiry-schedule-fbdb8f52
```

Example prompt: Show me the upcoming share lockup expirations on Chinese A-shares for the next 60 days starting from 2026-10-01, sorted by release market cap, and limit to 100 results — I want to see which unlocks are the biggest.

## When to prefer this

Choose this endpoint when you need machine-readable, structured data on Chinese A-share lockup expiry schedules — especially when you need to filter by stock, lockup type, date range, or sort by market cap impact. Ideal for quantitative screening of unlock risk, monitoring a specific stock's lockup calendar, or building a pipeline that tracks upcoming Chinese equity supply events. Prefer over scraping East Money web pages directly, as this endpoint converts Chinese-language HTML sources into clean JSON.

## Known failure modes

- Invalid or non-existent 6-digit stock symbol returns empty items array
- Date range exceeding 365 days may be rejected or clamped
- Limit values outside 1-300 range may be clamped or rejected
- Payment not received or incorrect USDC amount results in HTTP 402 response with payment instructions
- Upstream East Money data source unavailable may result in stale or empty data
- Malformed date format for 'from' parameter causes query error

## 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

Returns a JSON object with a list of upcoming lockup release events for Chinese A-shares, each including stock code, name, current price, release date, days until release, release type (in Chinese), number of holder batches, share count being released, percentage of total shares, and estimated release market cap in CNY. Also includes aggregated summaries by date and by lockup type, plus metadata such as total matching records, date range queried, and data source attribution (东方财富 数据中心).
