  1. """Zefix (Swiss central business index) collector — INTERFACE ONLY until token.
  3. The public REST API requires a registered (free) API token:
  4. - Request access / info: *** (official Federal Office of
  5. Justice contact, verified on bj.admin.ch 2026-09-23)
  6. - API docs (Swagger): https://www.zefix.admin.ch/ZefixPublicREST/swagger-ui/index.html
  7. Unauthenticated calls return 401 (verified 2026-09-23).
  9. Token-free alternative (official): opendata.swiss dataset "Zefix – Zentraler
  10. Firmenindex" exposes daily core data (name, seat, domicile of active entities)
  11. queryable via SPARQL on Lindas.
  13. Set the token in the environment variable configured under
  14. config/sources.json -> zefix.auth_env_var (default LEASH_ZEFIX_TOKEN),
  15. then flip zefix.enabled to true.
  17. Data (c) Swiss Confederation / cantons; respect Zefix terms of use.
