```

## When to prefer this

Use this endpoint when you need to programmatically verify whether a specific date is a valid working/business day in a particular country, especially when scheduling payments, contract deadlines, or automated workflows that must land on a business day. Ideal for multi-country business logic where public holiday calendars vary.

## Known failure modes

- Invalid date format (not YYYY-MM-DD) returns a 400 error
- Unsupported or invalid ISO country code returns an error or unexpected results
- Dates far in the future may have incomplete public holiday data
- Network or service unavailability returns a 5xx error
- Payment failure via x402 protocol prevents access

## How this service works

Check if a specific date is a business day in a given country. Accounts for weekends and public holidays. Also returns the next business day if the given date is not one.

## Output

Returns a boolean indicating whether the queried date is a business day in the given country, along with the next business day date if it is not, accounting for both weekends and country-specific public holidays.
