Tools

• check_dph_payer — full reliability check for a single subject (by IČO or DIČ). Returns status, subject type, name, address, transparent bank accounts, and unreliable-since date when applicable.
• check_bulk_dph_payer — batch up to 100 subjects in one ADIS request (lighter response: status + accounts only).
• list_unreliable_payers — full list of currently unreliable Czech VAT payers from ADIS. Large response (50–100 MB) — intended for daily mirroring rather than ad-hoc lookup.

Status meanings

| Status | Meaning | |---|---| | ANO | Subject is currently flagged as an unreliable VAT payer (nespolehlivý plátce / nespolehlivá osoba). | | NE | Subject is a VAT payer in good standing. | | NENALEZEN | Subject not found in ADIS — typically not a VAT payer. |

Example prompts:

Check VAT-payer reliability for IČO 12345678.

Among these 30 invoice issuers, list any that are currently unreliable VAT payers.
