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 containing: the requested date range, a day-by-day calendar array (each entry has date, weekday, isTradingDay, isHoliday, holidayName, isMakeupWorkday, calendarKnown), aggregate counts of trading days and closed days in the window, and the date of the next upcoming trading day.
Example use cases
Planning trades around Golden Week
“I need to know which days the Chinese stock market is open during the October Golden Week holiday period — can you check from October 1st for the next 10 days and tell me when trading resumes?”
Scheduling automated settlement jobs
“What are all the trading days on the Chinese market for the next 30 days starting today? I want to know exact dates so I can schedule my settlement batch jobs correctly.”
Checking next trading day after holiday
“It's Chinese New Year and the market has been closed — can you tell me what the next trading day on China's A-share market is, starting from January 28th, looking ahead 7 days?”
Technical details
Endpoint
GEThttps://cn-data-x402.cn-data-x402-worker.workers.dev/cn/trading-days?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need authoritative, machine-readable Chinese A-share market open/close status — especially when other sources only publish this as a Chinese-language web page. It is ideal for agents scheduling financial workflows, settlement jobs, or trade execution around official Chinese market calendars. At $0.01 USDC per call with no signup, it is the lowest-friction option for one-off or automated calendar lookups on China's stock markets.
Side effects
- Invalid date format for `from` parameter — endpoint expects YYYY-MM-DD
- `days` parameter out of range (must be 1–30) — may return error or clamp
- Payment not completed — returns HTTP 402 with USDC payment terms before data is served
- Future dates beyond known holiday schedule may have calendarKnown=false entries
- Network timeout on Cloudflare Worker edge node
