Phone Number Validation API

This server validates phone numbers globally using the phone-validation API at klymax402.com, exposing carrier detection, line type identification, country lookup, and E.164 formatting. It integrates x402 micropayments in USDC, so you're paying per validation request rather than subscribing to a monthly plan. Reach for this when you need to verify phone numbers in user input, clean up contact databases, or determine whether a number is mobile or landline before sending SMS. The remote SSE transport means it runs externally and bills as you use it. If you're building customer onboarding flows or contact verification systems and want global phone intelligence without maintaining your own validation infrastructure, this handles the heavy lifting.
