SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Verifying Czech companies and sole traders requires manually searching multiple public registers. This Skill wraps the official ARES v3 REST API into a single CLI so you can look up any economic subject by IČO or name and get structured JSON data instantly. ## Core Features & Use Cases - Company Identification: Retrieve basic identification records (name, address, legal form, dates of establishment/termination) by IČO or name search. - Register-Specific Lookups: Query the business register (statutory bodies, partners, capital), statistical register (NACE, employee counts), and trade licence registry (živnosti) via dedicated flags. - VAT Payer Verification: Check DIČ and current VAT-payer status from the basic detail record. - Use Case: Before signing a contract, verify a counterparty by running a detail lookup on their IČO to confirm the company is active, see who its statutory representatives are, and check whether it is a registered VAT payer. ## Quick Start Ask the AI to verify the company with IČO 27082440 in ARES, including its address, statutory body, and VAT payer status.

Frequently Asked Questions about ares

FAQPage Schema
How do I look up a Czech company by IČO in ARES?▼

Run ares-cli detail followed by the IČO, for example ares-cli detail 27082440. The tool left-pads shorter inputs to 8 digits and returns the full ARES JSON record, which you can filter with jq for fields like obchodniJmeno and sidlo.textovaAdresa.

How to find statutory bodies and partners of a Czech company?▼

Use ares-cli detail with the --register vr flag to query the business register. Statutory bodies appear under zaznamy[].statutarniOrgany and partners under zaznamy[].spolecnici; iterate over the arrays since multiple records can exist.

Can I check if a Czech company is a VAT payer through ARES?▼

Yes, VAT status is available in the basic detail record since ARES v3 has no dedicated VAT endpoint. Read the dic field and seznamRegistraci.stavZdrojeDph, which reports AKTIVNI, UKONCENY, or NEEXISTUJICI.

Can I search ARES companies by city or postal code?▼

No, the ARES v3 search endpoint has no address, obec, or PSČ filter. Search by name, IČO, or legal form code with --pravni-forma, then read each result's address from sidlo.textovaAdresa.

What should I do when ares-cli returns an ERROR?▼

Read the ERROR line, which includes the HTTP code and the verbatim ARES error body, then report it rather than guessing workarounds. When looking up multiple subjects, run each independently since one failure does not affect the others.
