#cities

Geographic data for AI agents — 250+ countries, states, cities, IP geolocation, and live exchange rates (161 currencies) updated every 4 hours.

cityparity gives AI agents real cost-of-living and quality-of-life comparison tools. Point it at two cities and it returns take-home pay, a full cost breakdown (housing, healthcare, childcare, food, transit, travel home, property tax), and the equivalent salary you'd need in the target city to come out even. It also surfaces the non-cash deltas people actually move for: vacation days, parental leave, universal healthcare. Beyond two-city compares, it ranks cities by a composite quality score and looks up inbound-worker tax regimes (Italy impatriati, Portugal IFICI, and a few others). Over 165 cities across 69 countries. Free, no API key, hosted Streamable HTTP.
