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.

Data comes only from sources that allow commercial reuse, such as Wikidata, Unicode CLDR, UK FCDO, the US State Department and Japan MOFA. Entry answers quote official government pages and are decision support, never a go/no-go verdict. Remote MCP server (Streamable HTTP, 9 read-only tools) and REST API (OpenAPI 3.1).
