Machine access and service level

The service level we impose on ourselves

Regulation (EU) 2023/138 requires Member States to publish certain datasets — so-called high-value — free of charge, machine-readable, with an API and bulk download. We apply that level to this register, whether the law requires it or not.

  • Free of charge — every page and every machine file on this site is freely accessible, with no account and no key.
  • Machine-readable — manifest, field schema, real sample.
  • With an API — 6 callable tools, described with their input schema and wired into the page for an agent.
  • And as a bulk download — 97 fragments covering the whole dataset, enumerable and free.

⚠️ This register is not designated « high-value » in the legal sense: it is a service level we impose on ourselves, not a regulatory guarantee. Details for agents · catalogue.

Machine access8/9

This is not a badge: every line points to the file that proves it, and the only missing one is listed too.
