How this service works
X402 micropayments server — AI agents pay USDC for OFAC screening, rates, and billing verification.
Output
Returns a JSON object with a 'result' field containing phone number intelligence data (such as carrier, line type, country, and validation status) and a 'success' boolean indicating whether the lookup succeeded.
Example use cases
Validate customer phone during signup
“Before we complete this user's registration, can you check if +442071234567 is a real, valid phone number and tell me what type of line it is — mobile, landline, or VoIP?”
Enrich CRM contact record
“I have a contact in my CRM with the phone number 2025550123 in the US — can you look up the carrier and line type so I can update their record?”
Screen phone number before SMS campaign
“We're about to send an SMS campaign — can you check if +49301234567 is a mobile number and which carrier it's on so we know if it's reachable by text?”
Technical details
Endpoint
GEThttps://x402helper.xyz/89e509/phone/intel?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need per-call phone number intelligence at low cost ($0.006 USDC) and are already operating in an x402 micropayment-enabled agent environment. It is suitable for one-off lookups, CRM enrichment, pre-send validation for messaging campaigns, or fraud screening pipelines where paying per lookup is preferable to a monthly subscription. Supports both E.164 and national format inputs with optional country code.
Side effects
- Missing required 'number' query parameter returns an error
- Invalid or unrecognizable phone number format may return an empty or failed result
- Number provided without country code in national format without 'country' param may fail to parse
- Payment failure via x402 protocol blocks access entirely
- Rate limiting or quota exhaustion may return a 402 or 429 error
