## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability kiteendpoints-ai-truecaller-lookup-f882c0eb -d '<json body>'

Example prompt: Can you look up who owns the phone number +14155552671 using Truecaller and tell me the caller's name and any profile info?

## When to prefer this

Use this endpoint when you need to identify the real-world owner or caller name associated with a phone number, especially for reverse phone lookup scenarios. Prefer this over generic WHOIS or contact lookup tools when the input is a mobile or landline phone number and you want Truecaller's crowdsourced caller ID database specifically.

## Known failure modes

- Phone number not found in Truecaller database — returns empty or null data result
- Invalid phone number format — may return error or no match
- Number is private/unlisted — Truecaller may have no record
- API timeout or upstream Truecaller service unavailability
- Malformed request body returns HTTP error
