CitedTravel

Turns a country name, alias or code (English, Japanese or Chinese) into ISO 3166-1 codes. Returns matches[] (iso2, iso3, name, matched, score 0-1), best first, at most 5; empty when nothing matches. Use it first whenever you only have a name: every other tool (get_country_facts, check_entry_requirements, get_trip_brief and the rest) takes ISO codes. Skip it when you already have an alpha-2 or alph

Cited facts for one country in one call: power (plug_types, voltage_v, frequency_hz), currency (currencies), emergency (numbers), driving (side), this calendar year's public holidays and tipping (norms). Returns data.<category>.<field> = fact. Use it when you want several of these facts for one country at once (e.g. a destination overview), or to pick a subset with categories. For a single topic u

Whether a traveller from home_country needs a plug adapter or a voltage converter in destination, computed deterministically from cited plug, voltage and frequency facts. Returns verdict {adapter: not_needed | needed | depends_on_plug, converter: not_needed | usually_not_needed | needed_for_single_voltage_devices | unknown, plug_fit[] (home plug -> destination sockets it fits), frequency_note, gui

Emergency phone numbers for one country. Returns data.numbers.value {police, ambulance, fire, general, all_numbers}; a service without its own number is null and reached via general. Use it when only the emergency numbers are needed, e.g. a safety question. For several fact types of one country use get_country_facts; for a whole trip use get_trip_brief, which includes these numbers per destination

Tipping customs for one country. Returns data.norms.value {overall_context, situations: {<situation>: {display, expectation, guidance_type, percent_min, percent_max}}}; percentages are given only where the source states them. Use it for "should I tip, and how much?"; pass situation to get one situation only. For several fact types of one country use get_country_facts; for a whole trip use get_trip

National public holidays of one country between two dates (at most two years apart). Returns data.holidays[] {date, name, fact_id} sorted by date, and data.facts[] with the citation of each calendar year covered (holiday_count instead of the list). Use it to check whether travel dates hit holidays (closures, crowds, prices). For this year's holidays together with other facts use get_country_facts;

Visa/entry information for a short tourist stay, for a pilot set of passports, from official government sources, with verbatim quotes, official links and a mandatory advisory. Decision support only: never a go/no-go verdict. Returns status (visa_free, visa_free_with_requirements, visa_on_arrival, eta_required, evisa_required, visa_required or unclear), status_by_source, prior_application_needed, m

Whole-trip brief for 1-5 destinations in one call. For each destination, in request order: entry (the check_entry_requirements answer, if passport is given), power (adapter/converter verdict from home_country), currency, emergency numbers, driving side, tipping, and public holidays between from and to. Use it to summarise a whole trip. When only one fact is needed use the single-topic tool instead

Change feed of the dataset: facts added, updated or removed since a date, newest first. Returns data[] {seq, changed_on, dataset_version, fact_id, country, category, change: added | updated | removed, old_value, new_value, source_url}. Use it to refresh a cache or alert users when something changed (e.g. a visa rule). To read current values with full citations, call the matching tool for that coun
