Tools
check_dph_payer
Use it to check one Czech subject’s VAT-payer reliability, registered accounts, and tax-registry details by IČO or DIČ. Do not use it for a supplier portfolio; use the bulk tool instead.
check_bulk_dph_payer
Use it to screen a list of Czech IČOs and/or DIČs in one request, up to the service limit. Do not use it when full name and address details for one subject are required; use check_dph_payer.
list_unreliable_payers
Use it for a scheduled mirror or local-data refresh of all currently unreliable VAT payers. Do not use it for an ad-hoc lookup: the source list is 50–100 MB and may contain tens of thousands of entries; use check_dph_payer instead.
Status meanings
Example prompts:
