How this service works
FastX402 Lab: small pay-per-call tools for AI agents, paid per request in USDC on Base over x402. No signup, no API key.
Output
A JSON object containing the queried date and country code, a boolean 'is_holiday' flag, and if it is a holiday, a nested 'holiday' object with the official name, local name, types (e.g. Public, Bank), and boolean flags for whether it is globally recognized and publicly observed.
Example use cases
Pre-scheduling delivery blackout dates
“Before I schedule the courier pickup for December 26, 2025 in the UK, can you check if that date is a bank holiday so we can avoid delays?”
Payroll processing date validation
“We're running payroll on July 4, 2025 — can you confirm whether that's a public holiday in the US so we know if banks will be closed?”
International meeting planning
“I'm trying to book a meeting with our German team on October 3, 2025 — is that a national holiday in Germany?”
Technical details
Endpoint
GEThttps://lab.fastx402.tools/holiday-date-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, no-signup, pay-per-call check for whether a specific calendar date is a public holiday in a given country. It is ideal for AI agents that need occasional, on-demand holiday verification without managing API keys or subscriptions. Prefer this over larger calendar APIs when cost-per-call economics matter and you only need single-date lookups rather than bulk calendar data.
Side effects
- Invalid country code returns an error or empty holiday response
- Malformed date format (not YYYY-MM-DD) causes a validation error
- Date outside supported range may return is_holiday: false with no holiday data
- Network or payment failure (x402 USDC payment not processed) results in HTTP 402
- Non-existent or unsupported region returns no holiday data
