validate_nifValidates a Portuguese NIF (Número de Identificação Fiscal) — the 9-digit tax identification number issued by the Portuguese Tax Authority (AT) to individuals and companies. Applies the official modulo-11 checksum algorithm to verify the check digit. Returns { valid: true, nif: string } for valid NIFs, or { valid: false, reason: string } for invalid format or failed checksum. First-digit rules are enforced: 1–3 for individuals, 5 for corporations, 6 for public entities, 7–8 for other entities, 9 for occasional taxpayers. Use when processing Portuguese invoices (faturas), onboarding suppliers, validating user registrations, or any fiscal compliance workflow. Does not query the AT database — offline format and checksum validation only.
validate_ibanValidates an IBAN (International Bank Account Number) using the ISO 13616 MOD-97 algorithm. Supports 18 European countries: PT, ES, FR, DE, IT, NL, BE, PL, SE, DK, FI, AT, IE, GR, HU, RO, CZ, HR. Returns { valid: boolean, country: string, iban: string } — country is extracted from the 2-letter prefix. Returns { valid: false, reason: string } for malformed input. Spaces are automatically stripped before validation. Use when validating supplier bank details for SEPA transfers, processing direct debit mandates, verifying payment data in e-commerce checkouts, or any workflow requiring a verified EU bank account number. Validates structure and checksum only — does not confirm account existence.
get_vat_rateReturns all VAT (Value Added Tax) rates for a given EU country — standard, reduced, intermediate, and super-reduced rates where applicable, as numeric percentages. Returns { country, standard, reduced?, intermediate?, superreduced? } for supported countries, or { error, available } listing all valid codes if the country is not found. Supports 18 EU member states: PT, ES, FR, DE, IT, NL, BE, PL, SE, DK, FI, AT, IE, GR, HU, RO, CZ, HR. Use when calculating EU cross-border invoice tax, determining correct rate for e-commerce checkout by customer country, generating compliant VAT breakdowns, or any workflow requiring accurate and current EU VAT rates per jurisdiction.
get_portugal_holidaysReturns all Portuguese national public holidays for a given year as a structured list. Each holiday includes { date: 'YYYY-MM-DD', name: string, name_en: string }. Returns 10 mandatory national holidays defined by Portuguese law. Use when calculating business deadlines, delivery dates, payment due dates, SLA periods, or scheduling tasks that must avoid non-working days in Portugal. Does not include municipal or regional holidays (e.g. Lisbon June 13, Porto June 24) which vary by city.
format_number_europeanFormats a number using the locale conventions of a specific European country, applying the correct decimal separator and thousands separator. Returns { original: number, formatted: string, locale: string, country_code: string }. Different European countries use different conventions — Portugal and most of continental Europe use '1.234,56' (dot as thousands, comma as decimal), while Ireland uses '1,234.56'. Supports PT, ES, FR, DE, IT, NL, BE, PL, SE, DK, FI, AT, IE, GR, HU, RO. Use when displaying prices, measurements, or any numeric value to end users in a specific European country.
validate_nif_esValidates Spanish tax identification numbers — NIF (DNI, 8 digits + check letter, for Spanish citizens), NIE (Número de Identidad de Extranjero, starts with X/Y/Z, for foreign residents), and CIF (Código de Identificación Fiscal, letter + 7 digits + control, for companies). Automatically detects the document type. Returns { valid: boolean, type: 'NIF'|'NIE'|'CIF', id: string }. Use when processing Spanish invoices, e-commerce orders, supplier registrations, or any document requiring a verified Spanish fiscal identifier.
calculate_working_daysCounts the number of working days between two dates (inclusive), excluding Saturdays, Sundays, and all 10 Portuguese national public holidays. Returns { start_date, end_date, working_days: number }. Use when calculating Portuguese invoice payment deadlines (30/60/90 days), legal notice periods, project milestones, SLA response times, or any business process governed by Portuguese working days. Input dates must be in YYYY-MM-DD format.
get_spain_holidaysReturns all Spanish national public holidays for a given year as a structured list. Each holiday includes { date: 'YYYY-MM-DD', name: string, name_en: string }. Returns 9 mandatory national holidays defined by Spanish law. Use when calculating business deadlines, delivery dates, or scheduling tasks that must avoid non-working days in Spain. Does not include regional holidays that vary by autonomous community (Catalonia, Madrid, Andalusia, etc.) — only nationally mandated holidays are returned.
validate_siretValidates a French SIRET (Système d'Identification du Répertoire des Établissements) number using the official Luhn algorithm. SIRET is a 14-digit number — the first 9 digits are the SIREN (company identifier) and the last 5 digits identify the specific establishment. Returns { valid: boolean, siren: string, establishment: string, siret: string }. Use when processing French invoices (factures), validating supplier registrations, or any B2B transaction requiring a verified French business establishment identifier. Handles the La Poste special case automatically.
validate_tva_frValidates a French TVA intracom (VAT) number — the EU VAT identifier for French companies. Format is 'FR' + 2 alphanumeric key characters + 9-digit SIREN. Returns { valid: boolean, key: string, siren: string, tva: string }. When the key is numeric, validates using the official formula: key = (12 + 3 × (SIREN mod 97)) mod 97. Use when validating French supplier VAT numbers, processing cross-border EU invoices, or any intra-EU transaction requiring a verified French VAT identifier.
get_france_holidaysReturns all French national public holidays for a given year as a structured list. Each holiday includes { date: 'YYYY-MM-DD', name: string, name_en: string }. Returns 11 mandatory holidays defined by French law. Easter-dependent holidays (Easter Monday, Ascension Thursday, Whit Monday) are dynamically calculated for the requested year using the Anonymous Gregorian algorithm. Use when calculating French business deadlines, delivery dates, or scheduling tasks that must avoid non-working days in France.
