Public holidays API by country and year

$0.01 per call · failed calls are never charged · no account or subscription: pay per call with a card key or USDC

Nationwide public holidays for a year in the US (federal), UK (England and Wales), Sweden, Germany, France, Norway, Denmark and Finland: date, local and English name, and the weekday it is observed on where a weekend moves it. Computed from statutory rules for 2024-2100. Use for scheduling, delivery dates and business-day maths.

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://tools.funwords.eu/holidays?country=SE"

Or one of your 25 free calls, no key:

curl "https://tools.funwords.eu/holidays?country=SE&trial=1"

Without a key, the same URL answers 402 Payment Required with x402 and MPP terms, so an agent with a wallet pays per call in USDC (Base, Polygon, Arbitrum or Solana over x402; Base or Tempo over MPP) and retries.

Questions

Which countries?

Countries covered by the Nager.Date public holiday data, by two-letter code.

How do I pay?

Each successful call costs $0.01; failed calls are not charged. The first 25 calls are free. Then pay with card credits (from $1; the key goes in an Authorization header or, for clients that can only fetch a URL, as api_key= in the URL) or per call in USDC over x402 or MPP. No account is needed.
