Environment variables
  • COMPANIES_HOUSE_API_KEYsecretCompanies House REST API key, required for the United Kingdom (GB). Free from developer.company-information.service.gov.uk. Unset means GB lookups return an upstream_error naming this variable; every other country still answers.
  • BOLAGSVERKET_CLIENT_IDsecretBolagsverket OAuth 2 client id, required for Sweden (SE) together with BOLAGSVERKET_CLIENT_SECRET. Free, no contract: request both from Bolagsverket's kundanmälan form. Unset means SE lookups return an upstream_error naming both variables; every other country still answers.
  • BOLAGSVERKET_CLIENT_SECRETsecretBolagsverket OAuth 2 client secret, the other half of BOLAGSVERKET_CLIENT_ID. Both are needed before Sweden (SE) can answer.

A starting point — check the repository for exact arguments and setup. Restart your client after editing the config.
