Overview

DatoCapital v3 is a read-only REST API serving companies, directors, and filings — densest in the major European registries (Spain, UK, Netherlands, Luxembourg, Malta, Gibraltar) and well-covered for offshore centres (BVI, Cayman, Panama, Bermuda).

What's here

• /v3/companies — list (filterable, geo-aware, full-text), single profile, secondary URL form by registry id, filings sub-resource.
• /v3/individuals — full-text person search, single profile by opaque id.
• /v3/suggest — typeahead against company and individual cores.
• /v3/reference/* — country and company-type catalogs.
• /v3/whoami — your plan + every entitlement rule the catalog applies to your tier.

Conventions

• Authentication — bearer token in Authorization: Bearer .... Read more.
• Identifiers — public ids are opaque (UEC for companies, id_cod for individuals and filings). Internal numeric ids never leak.
• Pagination — opaque cursors. No page / offset parameters.
• Errors — RFC 9457 problem documents on every non-2xx response.
• Tier gating — endpoints return 403; fields silently suppress. Inspect /v3/whoami.entitlements to learn what your plan unlocks.
• Localisation — pass ?language=en|es|fr|nl for status / inscription type labels where supported.

Versioning

The major version is in the URL (/v3). We add fields and endpoints freely; we never remove or rename a field within a version. Deprecation goes through a header with a sunset date.
