Publisher-provided text

• company_lookup Basic register (ARES) lookup: name, legal form, registered address, NACE, data-box, VAT DIČ. Input: IČO (8 digits) or DIČ (CZ+10).
• check_vat Plátce-DPH status from the ARES RZP record, cross-checked against the ARES DPH source flag. RZP is a HISTORICAL register (records can stop updating in 2016), so
• entity_status KYC-style snapshot: active/cancelled, which registers the entity appears in (VR, RZP, IR insolvency, NRPZS, RCNS, SZR...), plus an insolvency presence flag (IR)
• search_company Company-name search in ARES (prefix match, case-insensitive; no wildcards). Returns IČOs + names + addresses for further lookups.
• validate_cz Checksum/format validation: IČO (mod-11), DIČ (CZ+IČO or birth number), IBAN (mod-97, CZ-specific), variable symbol. Pure local, no network.
• address_check Free-text Czech address -> RÚIAN-standardized (full KOD ADM, codes for obec/část/ulice, correct PSC).
