## When to prefer this

Choose this endpoint when you need reliable, auditable business day verification across 27 countries with cryptographic audit trails — ideal for financial workflows, contract scheduling, or compliance use cases where you need a verifiable record of the check. Prefer it over building your own holiday calendar logic or using general-purpose date libraries that lack country-specific public holiday data.

## Known failure modes

- Invalid date format (not YYYY-MM-DD) returns a validation error
- Unsupported or invalid ISO country code returns an error
- Country code outside the 27 supported countries may return no data or an error
- Network timeout or service unavailability returns a 5xx error
- Missing required query parameters (date or country_code) returns a 400 error

## 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 whether the specified date is a business day in the given country, along with an audit record containing a cryptographic chain hash for verification and traceability of the result.
