What this server can do
5 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.
decode_vin(vin, x_payment)- PAID $0.002 (x402, USDC on Base). Decode a Vehicle Identification Number: give {vin} and get a 17-char format + North-American check-digit validation and a full decode via NHTSA's public vPIC API — make, model, year, body class, engine, plant country and more. VIN-only (never plate→owner). Without payment returns the x402 challenge; pass x_payment to settle. Required: vin.
geo_lookup(city, query, state, country, x_payment)- PAID $0.002 (x402, USDC on Base). Resolve a place against a bundled open dataset (no per-day API limits). Give {query:"Munich, Bavaria, Germany"} OR {country, state, city} and get normalized names, ISO 3166-1/-2 codes, the country→subdivision→city hierarchy, population and coordinates, and confirmation the place exists. Without payment returns the x402 challenge; pass x_payment to settle.
validate_email(email, x_payment)- PAID $0.002 (x402, USDC on Base). Validate an email address: give {email} and get RFC-ish syntax validation, a LIVE MX-record (DNS) existence check, disposable/throwaway-domain detection (bundled blocklist), and a role-address flag (info@, admin@…). STATELESS and non-PII — the address is never stored and no SMTP mailbox is probed. Without payment returns the x402 challenge; pass x_payment to settle. Required: email.
validate_iban(iban, x_payment)- PAID $0.001 (x402, USDC on Base). Validate an IBAN: give {iban} and get ISO 13616 length + mod-97 checksum validation, the country, the human-formatted grouping, and the bank identifier (e.g. German Bankleitzahl, UK bank code + sort code) extracted from the BBAN where derivable. Pure-offline. Without payment returns the x402 challenge. Required: iban.
validate_vat(x_payment, vat_number, country_code)- PAID $0.003 (x402, USDC on Base). FLAGSHIP. Validate an EU/EEA VAT number: give {country_code, vat_number} and get a per-country format + checksum pre-check AND a LIVE lookup against the official VIES service — returning valid/registered plus the registered company name & address when VIES provides them (cached ~1h to shield the flaky VIES). Without payment returns the x402 challenge; pass x_payment to settle. Required: country_code, vat_number.

Signals
These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.
