About this API
INE (Instituto Nacional de Estadística) is the Spanish equivalent of Poland's GUS — its Tempus3 database exposes the entirety of Spain's official statistics through a simple REST API returning JSON, with no registration required.
Frequently asked questions
Do I need an API key?

Can this API be called directly from a browser?
Yes — the API returns a CORS header allowing calls from any domain, so it works directly from frontend code (hence the live "Try it" button above).
