Verified validation of structured identifiers — IBAN, payment cards, ISBN-13 and VIN — for AI agents. Runs the real checksum algorithms (mod-97, Luhn, mod-10, ISO 3779) instead of letting the model guess, and returns structured results with clear errors.

Verified locale data for AI agents: dates, phone numbers, currency formatting, VAT/sales-tax by date, public holidays, and addresses (UK & US). Returns checked answers and flags impossible inputs instead of guessing.
