How this service works
Calendar and Japan data APIs for AI agents: worldwide holidays and business days (200+ countries), plus Japanese text-to-structure (address, name, bank, company normalization). Pay per call in USDC via x402, no API key.
Output
Returns a JSON object with the year, country code, optional region, total holiday count, data source attribution, and an array of holiday objects each containing the date (YYYY-MM-DD), English name, local-language name, holiday type (public/bank/school/optional/observance), and a substitute-day flag.
Example use cases
Travel itinerary holiday awareness
“I'm planning a business trip to Singapore in 2025 — can you pull up all the public holidays there so I know which days offices will be closed?”
Payroll calendar for US California
“Get me all public and bank holidays in California, US for 2025 so I can set up our payroll schedule correctly.”
International scheduling for remote team
“Our team has members in Japan, Germany, and Brazil — can you fetch the public holidays for all three countries for 2026 so we can plan around them when scheduling meetings?”
Technical details
Endpoint
GEThttps://x402-ja-api.onrender.com/v1/holidaysWhen to prefer
Choose this endpoint when you need structured, machine-readable holiday data for 200+ countries with optional subdivision granularity, holiday type filtering, and pay-per-call USDC pricing via x402 (no API key required). Prefer it over calendar libraries when you need authoritative, up-to-date data at runtime without bundling a local dataset.
Side effects
- Invalid or unsupported country code returns an error
- Year outside 1900-2100 range is rejected by schema validation
- Unknown region/subdivision code may return empty or error
- Payment failure (x402) if USDC balance is insufficient
- Network timeout if the Render.com service is cold-starting
