How this service works
Public holidays and business-day calculator for agents, ~120 countries: holiday lists, is-this-a-business-day, and add N business days. Paid per call via x402 (USDC on Base).
Output
A JSON object containing the country code, year, and an array of public holidays each with a date (YYYY-MM-DD) and holiday name. For business-day queries, returns whether a specific date is a business day or a computed future business date.
Example use cases
Payroll business-day scheduling
“I'm running payroll for our US office — if payday falls on July 4th 2025, what's the next valid business day I should process payments?”
International meeting planner
“We're scheduling a call with our German team in late October 2025 — can you check which days are public holidays in Germany so we avoid scheduling on those?”
Contract deadline calculation
“Our contract says the client has 15 business days to respond after we send the proposal on March 10 2025 in the UK — what's the deadline date?”
Technical details
Endpoint
GEThttps://holidays.x402utils.workers.dev/v1/holidays?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need authoritative public holiday data for ~120 countries with minimal setup, especially when integrating into agent workflows that require business-day awareness (scheduling, payroll, contract deadlines). It's ideal for AI agents that need to programmatically validate or compute calendar dates across international markets without managing holiday datasets themselves.
Side effects
- Unsupported country code returns an error or empty holiday list
- Invalid or missing 'country' query parameter results in a 400 bad request
- Year out of supported range may return an empty or partial response
- Network or payment (x402) authorization failure returns a 402 Payment Required response
- Ambiguous country codes (e.g. territories vs. sovereign states) may yield unexpected results
