## Tools
- validate_vat (Validate an EU VAT number via VIES (paid $0.003)) - 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. Endpoint: https://valid.fabtally.com/mcp
- validate_iban (Validate an IBAN (mod-97) + extract bank code (paid $0.001)) - 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. Endpoint: https://valid.fabtally.com/mcp
- validate_email (Validate an email: syntax + MX + disposable + role (paid $0.002)) - 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. Endpoint: https://valid.fabtally.com/mcp
- geo_lookup (Resolve a country / state / city to ISO codes (paid $0.002)) - 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. Endpoint: https://valid.fabtally.com/mcp
- decode_vin (Decode a VIN via NHTSA vPIC (paid $0.002)) - 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. Endpoint: https://valid.fabtally.com/mcp
