Flagship.** EU/EEA VAT: `{country_code, vat_number}` → per-country format + checksum pre-check AND a **live VIES lookup**, returning valid/registered plus the registered company name & address when VIES has them (cached ~1h to shield the flaky VIES).
validate_iban
{iban}` → ISO 13616 length + **mod-97 checksum**, country, human-formatted grouping, and bank identifier (German Bankleitzahl, UK bank code + sort code, …) extracted from the BBAN where derivable. Pure-offline.
validate_email
{email}` → RFC-ish syntax + **live MX-record (DNS)** existence + **disposable/throwaway-domain** detection (bundled blocklist) + role-address flag (`info@`, `admin@`). Stateless & non-PII: the address is never stored and no SMTP mailbox is probed.
geo_lookup
{query:"Munich, Bavaria, Germany"}` or `{country,state,city}` → normalized names, **ISO 3166-1/-2 codes**, country→subdivision→city hierarchy, population and coordinates, over a bundled open dataset (no per-day API limits).
decode_vin
{vin}` → 17-char format + North-American **check-digit** validation and a full **NHTSA vPIC** decode: make, model, year, body class, engine, plant country. VIN-only (never plate→owner).
