OpenRegistry is a live proxy to 25 national company registries. Type a company name or registration number, pick a jurisdiction, and you get the registry's own response - verbatim, no aggregator markup, no stale cache. Each result row deep-links to a permanent company-profile page that's stable to cite or share.
Every search and company page is also served in machine-readable form for LLMs - no API key, no setup. Append a format extension to the URL:
GET /search.md?q={company}&jurisdiction={ISO} Markdown
GET /search.jsonld?q={company}&jurisdiction={ISO} Schema.org JSON-LD
GET /api/v1/search?q={company}&jurisdiction={ISO} JSON
Per-company data takes the same .md / .jsonld variants (or via Accept-header content negotiation):
GET /company/{cc}/{id} profile
GET /company/{cc}/{id}/officers directors
GET /company/{cc}/{id}/shareholders shareholders
GET /company/{cc}/{id}/financials financials
GET /company/{cc}/{id}/filings filing history
e.g. /company/gb/09446231/officers.md.
The full machine manifest - endpoints, jurisdictions, examples - is at /llms.txt.
