About this API
BORME (Boletín Oficial del Registro Mercantil) is the official gazette of the Spanish commercial register. The BOE open-data API exposes a daily summary — the day's company registry events (incorporations, capital and board changes, dissolutions) with links to the PDF and XML documents. Access is free and requires no key.

What data does this API return?
The daily BORME summary: the day's registry entries for Spanish companies — incorporations, capital and board changes, and dissolutions — with links to the PDF and XML documents.
Can this API be called directly from a browser?
It is a plain GET returning JSON, but the BOE service usually does not send CORS headers, so a server-side call is more practical.
