Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Czech VAT-payer reliability check (nespolehlivý plátce DPH). Use whenever the user asks about VAT status, transparent bank accounts (§ 96a ZDPH), or "is this company a reliable VAT payer?". Backed by the official MFČR ADIS SOAP service. Status meanings: NE = reliable (good), ANO = unreliable (red flag, must use a published account to avoid joint-liability under § 109 ZDPH), NENALEZEN = subject is not in the VAT registry. Free tier rate-limited; higher limits at https://cz-agents.dev/pricing.html.

Check VAT-payer reliability for a single Czech subject. Returns reliability status (ANO/NE/NENALEZEN), subject type (VAT payer / identified person / VAT group / unreliable person / not found), name, address, published bank accounts (§ 96a ZDPH), and the date the subject became unreliable (when applicable). Returns null when the DIČ is not in the VAT registry.

Bulk reliability check for up to 100 Czech subjects in one ADIS request. Lighter than the single-subject check — returns reliability status, accounts, and tax office, but no name/address. Useful for screening invoice-issuer lists or supplier portfolios. Returns one entry per input DIČ; entries with reliability NENALEZEN indicate the subject is not in the VAT registry.

Return the full list of currently unreliable Czech VAT payers from ADIS. WARNING: response can be 50–100 MB (tens of thousands of entries). Intended for daily mirroring into a local database, not for ad-hoc inspection. For "is this specific company unreliable?" use check_dph_payer instead.
