The level of service we hold ourselves to
Regulation (EU) 2023/138 requires States to publish certain datasets — called high-value — free of charge, in machine-readable form, with an API and bulk download. We apply this level of service to this register, whether the law requires it or not.
- Free of charge — every page and every machine file on this site is open, with no account and no key.
- Machine-readable — manifest, field schema, real sample.
- With an API — 6 callable tools, described with their input schema, wired into the page for an agent, and the portfolio's MCP server.
- Bulk download — not served free here: the raw data can be downloaded free from the source, named in the footer; our normalised version is described on the data page.
This register is not designated “high-value” in law: it is a level of service we set ourselves, not a regulatory guarantee. Details for agents · catalogue.

Reading one record by its identifier
The lookup_record tool takes the dos id. For 7945326 it reads https://new-york-new-corporation-records.pages.dev/d/r/9f4.json (hash of the identifier: h = 0, then for each character h = (h*31 + character code) modulo 4096; in hexadecimal on 3 digits) and returns the record shown at https://new-york-new-corporation-records.pages.dev/search/#r=7945326.
