info:
  title: DatoCapital Health API

  summary: Commercial company-data REST API.
  description: 'Read-only access to companies, directors, and filings across the

    major European business registries plus a long tail of offshore

    jurisdictions.


    Authenticate with a bearer token (`Authorization: Bearer dc_…`).

    a page size limit; `/v3/whoami` shows the limits of your plan. See
