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 the format and check character of 18-character Unified Social Credit Identifier codes offline, while clearly stating what a passing code does not establish about the company.
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.
