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. Every value comes with its sources (publisher, URL, license, verbatim quote), a last-verified date and a 0-1 confidence score with reasons. 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). Answers in English, Japanese, Simplified and Traditional Chinese. Free: static facts need no key; a free key adds 1,000 calls/month. Paid: Builder $19/month, Pro $99/month, or x402 pay-per-call in USDC on Base.
SimFuse is a travel eSIM storefront covering 200+ countries and regions. This connector lets an AI assistant plan a trip, compare live prices and open a checkout for eSIM data. Browsing needs no authentication. What it does: - plan-trip: give the stops (country code and days in each) and it compares one plan covering the whole route against one plan per country against a mix, on live prices, then flags the cheapest complete option and lists any country it cannot cover. - list-destinations: search every country and region SimFuse sells for, with the cheapest plan price per destination. - list-plans and get-plan: browse a destination's plan ladder, filter by data amount, validity and price, and inspect a single plan in detail. - get-plan-coverage: check every country a plan works in before buying. - create-checkout-session: open a checkout for the selected plans at frozen prices. Nothing is charged by that call; payment, completion and cancellation happen over the agentic HTTP API with the returned key. Good to know: prices come back in minor units of the currency you ask for, data allowances are in megabytes, and quotes are offers rather than reservations, so the charged total is computed at checkout. Operated by Qorinx OÜ. Buy directly at https://simfuse.app, agent documentation at https://simfuse.app/agent/.
