Business Day & Deadline API
Business Day & Deadline API
All endpoints are GET with query parameters and cost $0.001 via x402 (USDC on Base). Use /v1/check to test if a date is a business day, /v1/add to add or subtract N business days to a date (deadline calculation), /v1/between to count business days between two dates, /v1/next and /v1/previous to roll to the nearest business day. Dates are ISO YYYY-MM-DD, country is ISO 3166-1 alpha-2 (DE, US, JP), region is an optional ISO 3166-2 subdivision suffix (BY for Bavaria, CA for California). Every response carries verifiedAt and source for auditability. GET /v1/schema and GET /health are free.
Indexed from this operator's public /.well-known/x402.json. Found is not operator-owned and is not attested. Claim or opt out.
