Reference data your agents won't hallucinate: time zones, public holidays and business days, sunrise and moon phases, unit conversion, country, currency and language facts, airports, US ZIP codes, NAICS codes, daily ECB exchange rates, and validators for IBAN, email, phone and card numbers. One key, every endpoint, JSON only, with an MCP server for agents. Operated by APIDirectory.
