Wego Countries API
Country-keyed reference data an agent can call before any search, and combine. `getCountryHolidays` returns a market's public holidays for spotting long weekends; `getVisaFreeDestinations` returns where a passport travels without a visa, as one complete list. Both take an ISO 3166-1 alpha-2 code as their only path key, which is what groups them under one tag – their results combine (visa-free supplies the destinations, holidays the free dates), rather than intersecting on a shared row field, since a holiday row carries no country code of its own. The visa list carries no visa type and no permitted stay – an absent country means absent from Wego's list, not that a visa is required.
