Check a Spanish company by API: what BORME gives

BORME gazette (BOE); Registradores by agreement only · not covered yet · checked 11 November 2026

The official route

The open route in Spain is BORME, the gazette that publishes registered company acts. It is part of the BOE's open data and has an API without any application:

https://www.boe.es/datosabiertos/api/borme/sumario/{yyyymmdd}

That returns the summary of one day. For section A (registered acts) you get one document per province, each listing that day's acts under the company name. Reuse is allowed if you name the source: "Fuente: Agencia Estatal BOE".

The per-company source is the service of the Registradores. It works by agreement only, and we have not found its terms. Insolvency itself is published in the Registro Público Concursal.

Where it gets hard

BORME is a gazette, so it cannot answer "what is the status of company X". We looked at it on 2026-11-09 and decided not to build on it. The reasons:

There is no query by company. Acts are listed by name only, without the NIF.
A status is the sum of every act since the company was founded, and BORME online starts in 2009. Companies founded earlier have no starting act.
The volume adds up. One day had 37 province documents of about 240 KB each. We estimated about 10,000 documents a year and about 170,000 since 2009.
Matching is by name and province, so namesakes and renames get in the way.
BORME only echoes insolvency for registered acts.

Scanning just the last few days would return "nothing found". People read that as "active", and that is false comfort.

One call

Bosco Labs does not read a Spanish register. A counterparty-check call for a Spanish company uses these sources today:

Check	Source for this country
Register status	The LEI record (GLEIF); companies without an LEI are not found
LEI status	GLEIF
Recent accounts	ESEF annual reports, listed companies only
VAT number	VIES
IBAN	ISO 13616 check digits
Company on sanctions lists	OFAC, UN, UK, EU and US export lists

Insolvency comes back unverified. If Spain matters to you, a short mail to support@boscolabs.dev helps: we order the next registers by what people ask for.
