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.
Validates Indian GSTIN numbers with structural checks, embedded PAN extraction, state-code lookup, and mod-36 check character validation, all via local compute.
Validates phone numbers and provides country calling codes, enabling AI agents to look up international dialing codes and filter by country name, ISO code, or calling code.
Validates EU and Northern Ireland VAT numbers against the official VIES service, returning validity, company name and address, and distinguishing invalid from unavailable. Supports bulk checking up to 100 VAT IDs.
