Example use cases
Verify caller identity before accepting calls
“I just got a call from an unknown number +1-202-555-0147. Can you look it up on Truecaller and tell me who it is and whether it's flagged as spam?”
Screen incoming calls for business support
“We're getting a lot of inbound calls from numbers we don't recognize. Can you check +1-415-555-0123 against Truecaller to see if it's a legitimate contact or potential spam before I call them back?”
Enrich customer records with identity data
“I have a list of phone numbers from new sign-ups and I want to match them with real names. Can you look up +1-212-555-0198 on Truecaller and pull back the registered owner's name and location info to verify their account?”
Technical details
Endpoint
POSThttps://kite-hub-v2.vercel.app/api/truecaller-lookupWhen to prefer
Use this endpoint when you need to identify the owner of an unknown phone number, especially when Truecaller's crowdsourced caller ID database is the preferred source. Best for reverse phone lookups on mobile numbers, spam detection, or enriching contact records with caller name data. Prefer over generic CNAM lookups when crowdsourced identity and spam scoring are important.
Side effects

- Invalid phone number format — API returns validation error
- Number exists but has no public name listing — partial result returned
- Rate limiting or quota exceeded — HTTP 429 or payment error
- Unparseable or non-E.164 phone number input
