# Global Trade Alert

> Global Trade Alert (GTA) documents government interventions that affect international commerce, and its API serves two families: the GTA data endpoints (the policy database: what governments announced) and the US tariff endpoints (TAU: the applied rate a shipment pays, computed from the full US tariff stack). Demo API keys are self-serve at https://globaltradealert.org/api-access.
