What AI says about World Data API

World Data API provides a single, unified API for global data—countries, cities, airports, timezones, holidays, currencies, languages, and climate—accessible via one endpoint and one API key with a consistent JSON schema. It cross-references data across domains so you can traverse relationships in one query, delivering sub-30ms responses and a single billing model instead of juggling multiple providers. The platform offers a free API key with 60 requests per day and tiered paid plans for higher usage, targeting applications in e-commerce, fintech, travel, scheduling, HR, and more.
