How this service works
Don't burn tokens on deterministic work. Go/no-go jobs first: payout preflight, text firewall (PII/secrets), budget check — then rails, calendars, finmath. x402 USDC on Base. UK + global. agent402.co.uk — not agent402.tools. $0.001–$0.002 USDC on Base. No API keys.
Output
Returns a JSON object with a 'valid' boolean, the 'country' code used, and 'business_days' integer representing the count of non-weekend, non-holiday days in the requested range.
Example use cases
SLA deadline calculation for contracts
“We signed a contract today, April 1 2025, with a 30-business-day delivery window in Germany — what's the actual calendar date that deadline falls on? Can you first tell me how many business days there are between April 1 and May 31 2025 for DE?”
Payroll processing day estimation
“Our payroll team in Singapore needs to know how many business days fall between January 1 2025 and January 31 2025 for SG — can you calculate that including local holidays?”
Trade settlement working day check
“I need to verify how many business days there are between June 10 2025 and June 20 2025 in Japan for a bond settlement calculation — please exclude weekends and JP public holidays.”
Technical details
Endpoint
GEThttps://agent402.co.uk/v1/time/business-days-staticWhen to prefer
Choose this endpoint when you need a fast, cheap ($0.001), deterministic business-day count using static holiday calendars — ideal for SLA math, settlement calculations, payroll windows, or any offline scheduling logic across US, Germany, France, Ireland, Japan, Australia, or Singapore. Prefer it over general-purpose date libraries when you need a consistent, pre-validated holiday dataset for multiple regions without maintaining your own holiday lists.
Side effects
- Invalid or missing date format (not YYYY-MM-DD) returns validation error
- Unsupported country code outside US/DE/FR/IE/JP/AU/SG returns error
- End date before start date may return zero or error
- Network timeout on rare occasions
- Payment failure via x402 protocol returns 402 before any computation
