lookup_by_ico | Get a single Czech company record by its IČO (8-digit Business ID). Returns official name, registered address, legal form, VAT ID (DIČ), founding date, and trade license activities. Returns null if IČO is not found in ARES. params: ico* |
search_companies | Search ARES by company name, city, street, PSČ, or NACE code. Combines all filters with AND. Useful when user knows name but not IČO, looking for companies in a building, or all businesses in a sector. params: query, city, street, psc, nace, pocet, start |
search_by_address | Find all companies registered at a given Czech address. Useful for due diligence (virtual offices, shell companies), real estate research, or competitor mapping in a building. params: street*, city*, psc, pocet |
search_by_nace | Find Czech companies by CZ-NACE activity code (economic sector classification). Example: "62" = IT, "47" = retail, "86" = healthcare. Optional city filter. Useful for market research. params: nace*, city, pocet |
get_bank_accounts | Get transparent bank accounts published for this company (only available for VAT-registered subjects). Useful to verify payment details on an invoice match the company. params: ico* |
get_statutaries | Get current statutory body (jednatelé, představenstvo, etc.) of a Czech company — who can legally act on its behalf. Returns active members only (with valid zápis, not yet removed). Essential for due diligence and compliance checks. params: ico* |
get_owners | Get owners of a Czech company from the Veřejný rejstřík (public register) — společníci (partners of s.r.o./v.o.s./k.s.) and akcionáři (shareholders of a.s.), with their share (vklad/splaceno/velikost podílu) exactly as published, including historical members with their date of removal (datum výmazu). Raw registry data only — no ownership scoring, risk assessment, or cross-company aggregation. Esse params: ico* |
validate_dic | Validate a Czech DIČ (VAT ID). Format check: "CZ" + 8-10 digits. For 8-digit tail (legal entities) also runs MOD11 checksum against the embedded IČO. params: dic* |
check_vat_payer | Check whether a Czech company is a registered VAT payer (plátce DPH). If yes, returns DIČ, financial office, and any transparent bank accounts (payment details). params: ico* |
get_history | Get historical record of a company (previous names, registered address changes, trade license history). Useful for due diligence. params: ico* |
watch_entity | Start onboarding for free monitoring of one Czech company by IČO. Stub only — persists nothing yet. Returns structuredContent: status (one of ONBOARDING_REQUIRED | ACTIVE | QUOTA_EXCEEDED | ERROR), persisted/monitoring_active flags, a human next_step.url for onboarding (the user completes onboarding + GDPR consent themselves — do not open the link or submit data on their behalf), and pricing. params: ico* |
