Three ways to use it

- Call the API. One API key, JSON in and out, from your CRM, dialer or form.
- Ask Claude. Add TrueSearch as a connector in Claude, ChatGPT or Cursor and ask it to clean a list.
Upload a CSV or Excel file. Get back every number marked valid or dead, mobile, landline or VoIP, with carrier.
Starter: $97/month for 5,000 numbers after the 7-day trial. Cancel anytime.
Questions
Can TrueSearch replace NumVerify?
For phone validation (valid or dead, line type, carrier) by bulk file, API or Claude connector, yes. If you rely on NumVerify for anything else, such as Do Not Call or litigator checks, TrueSearch does not offer that yet.
How do I move a list over?
Export your list as CSV or Excel and upload it. The phone column is found automatically, and the clean file comes back with valid, line_type and carrier columns.
How much does it cost?
Starter is $97/month for 5,000 numbers after a 7-day free trial (250 numbers). Growth is $299/month for 12,500 and Pro is $799/month for 33,000. A one-off list is $20 per 1,000 numbers.
Is my list stored?
No. Lists are processed and returned. We keep usage counts, not your numbers.
