Example use cases
Verify unknown caller identity during sales calls
“I just got a call from +1-415-229-3500 and I'm not sure who it is. Can you look them up on Truecaller and tell me if they're a legitimate business or if that number's been flagged as spam?”
Screen incoming leads before customer engagement
“We have a list of phone numbers from recent form submissions. Can you quickly check a few of them like +44-20-7946-0958 using Truecaller to verify they're real people and not spam callers before we follow up?”
Identify mystery contact in support ticket
“A customer support ticket came in from someone at +81-3-1234-5678 but we can't figure out who they are. Can you do a reverse lookup using Truecaller to find out their name and verify if that number is legitimate?”

Endpoint
POSThttps://blockbuster-ai.vercel.app/api/truecaller-lookup?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to identify the owner or caller identity behind a phone number using the Truecaller database, especially for reverse phone lookups, spam detection, or caller verification. Prefer this over generic WHOIS or carrier lookup tools when you need crowd-sourced caller name data from Truecaller's global database.

- Invalid phone number format — query rejected
- Number exists but has no public identity data
