How this service works
320+ pay-per-call API endpoints across accommodation, LLM, code execution, crypto, medical, finance, and more. One API, one payment. Powered by x402 protocol.
Output
Returns a result object containing the validation status of the phone number, its parsed/normalized form (e.g. E.164 format), country code, region, carrier, and line type (mobile, landline, VoIP, etc.), along with an overall status field indicating success or failure.
Example use cases
Verify user phone at signup
“Before I save this new user's profile, can you validate the phone number they entered — +447911123456 — and confirm it's a real, properly formatted UK mobile number?”
Sanitize a contact list
“I have a contact entry with phone number '(212) 555-0198' — can you validate it and give me back the properly formatted E.164 version along with the country and line type?”
Fraud screening on checkout
“A customer just submitted order with phone number +919876543210 — can you verify that number is valid and tell me what country and carrier it's associated with so I can flag anything suspicious?”
Technical details
Endpoint
POSThttps://whatchuneed.vercel.app/api/util/phone-validateWhen to prefer
Choose this endpoint when you need a quick, pay-per-call phone number validation without committing to a subscription API like Twilio Lookup or Numverify. Ideal for agents that only occasionally need to validate phone numbers, want to avoid managing API keys for a dedicated telecom service, or are already operating within the x402 payment ecosystem.
Side effects
- Invalid or unparseable phone number string returns an error status
- Missing 'input' field in request body causes a 400-level error
- Ambiguous local numbers without country code may fail to parse
- Rate limiting or payment failures via x402 protocol may reject the call
- Very obscure regional numbers may return incomplete carrier data
