Prompt given to every model

Z přiloženého dokladu vytěž údaje a vrať pouze JSON s těmito klíči:

supplier_name      název dodavatele (přesně jak je na dokladu, včetně diakritiky a právní formy)
supplier_id        IČO dodavatele
vat_id             DIČ dodavatele
invoice_number     číslo dokladu
payment_reference  variabilní symbol
issue_date         datum vystavení (YYYY-MM-DD)
tax_point_date     datum uskutečnění zdanitelného plnění, DUZP (YYYY-MM-DD)
due_date           datum splatnosti (YYYY-MM-DD)
net_by_rate        základ daně podle sazeb DPH, např. {"21": 18450.00, "12": 1200.00}
vat_by_rate        DPH podle sazeb, např. {"21": 3874.50}
total              celkem k úhradě (číslo, záporné u dobropisu)
currency           měna podle ISO 4217 (CZK, EUR, …)
bank_account       číslo účtu dodavatele (tvar předčíslí-číslo/kód banky) nebo IBAN

Pravidla:
- Údaje odběratele nevracej, jen dodavatele.
- Pokud údaj na dokladu není, vrať null. Nic si nedomýšlej.
- Pokud doklad neobsahuje rozpis DPH (neplátce, zálohová faktura), vrať net_by_rate a vat_by_rate jako null.
- Částky jako čísla s desetinnou tečkou, bez oddělovačů tisíců a bez měny.

How we score
