How this service works
Each paid call costs 0.01 USDC on eip155:8453 via x402 (exact scheme). Free: /health, /, /openapi.json, /llms.txt, /.well-known/x402.
Output
A JSON object with the queried date, a type field classifying it (e.g. 'adjusted_workday', 'holiday', or regular weekday), a boolean isWorkday field, the weekday name in Chinese, and a source object containing the official Chinese government document URL and document number (国办发明电 reference) supporting the classification.
Example use cases
Scheduling meetings around Chinese holidays
“I need to schedule a call with our team in Beijing on February 14, 2026 — can you check if that's actually a working day in China or if it's a holiday or makeup day?”
Automating payroll for China office
“For our payroll system, can you check whether October 11, 2025 is an official workday in China, including any 调休 compensatory adjustments?”
Validating delivery SLA during Golden Week
“We promised a 3-business-day delivery, and I want to confirm — is October 7, 2025 a real working day in China or part of Golden Week?”
Technical details
Endpoint
GEThttps://cn-holiday-x402.linholiday.workers.dev/is-workday?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need authoritative, government-sourced Chinese workday determinations that correctly handle 调休 (compensatory makeup workdays) — scenarios where a Saturday becomes a workday and a weekday becomes a holiday. This is more reliable than generic calendar libraries, which often miss official Chinese State Council holiday schedule adjustments announced annually.
Side effects
- Missing 'date' query parameter returns an error
- Malformed date format (not YYYY-MM-DD) returns a validation error
- Date outside supported calendar range may return no data or an error
- Payment failure via x402 protocol returns HTTP 402 before data is returned
- Network/Cloudflare Workers downtime returns HTTP 5xx
