Travel plug fit, outlet types, voltage and packing checklists. Free, read-only, no key.
Scored across 4 tools
Each tool occupies a distinct query shape: one country, two countries, plug type to countries, or plug type description. The descriptions explicitly cross-reference each other (e.g. 'for one country alone use country_plugs', 'to compare two countries use check_trip'), eliminating overlap.
All names are snake_case and readable, but two are verb-led (check_trip, find_countries_by_outlet) while two are noun phrases (country_plugs, plug_type). The mix is minor and each name still clearly signals its purpose.
Four tools is a tight, well-scoped surface for a narrow domain, and each tool maps to a distinct query direction with no redundancy. Nothing feels padded or missing at the count level.
The surface covers the four natural query directions (country lookup, country-pair compatibility, plug-to-countries, plug description) plus adapter/voltage/frequency details. Minor gaps exist, such as searching countries by voltage/frequency or bulk-listing all countries, but core workflows are fully served.
Check whether devices from one country will work in another, for questions like "do I need an adapter for Japan?" or "will my UK charger work in the US?". Use when both a home country and a destination are known; for one country alone use country_plugs. Takes an English country name or ISO code for each. Returns which plugs fit, whether an adapter is needed, whether a voltage converter may be needed, frequency differences, local notes, a packing checklist and a page url.
Inputs: to (required), from (required). Returns: to, fit, url, from, +12 more
Look up the outlet and plug types, mains voltage and frequency of one country, for questions like "what sockets does Italy use?". Use when no home country is given; to compare two countries use check_trip. Takes an English country name or ISO code. Returns the types, voltage and frequency, regional notes for travellers and a page url.
Inputs: country (required). Returns: credit, country, version
Search for every country whose wall outlets are of one plug type, for questions like "which countries use Type G?" or "where else does my Type C plug work?". Use when the question starts from a plug type rather than a place; for one known country use country_plugs. Takes an IEC letter from A to O. Returns the matching countries with their voltage, frequency and page urls.
Inputs: type (required). Returns: credit, version, countries, outletType
Describe one plug type itself: its standard, pin layout, whether it is earthed and which plugs its socket accepts, for questions like "what is a Type F plug?" or "does a Type C plug fit a Type F socket?". Not about any country: to list where a type is used call find_countries_by_outlet. Takes an IEC letter from A to O. Returns the plug and socket standards behind the letter.
Inputs: type (required). Returns: type, plugs, credit, sockets, +2 more

CitedTravel gives AI agents and developers travel facts they can cite. It covers plug types and voltage, currency, emergency numbers, driving side, public holidays (3 years) and tipping norms for 195 countries, plus a visa/entry pilot for GB, US and JP passport holders.
