## 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 phone-intelligence-lookup-68ab4a9d -d '<json body>'
```

Example prompt: Can you validate the phone number +14155552671 in the US and tell me whether it's a real active mobile line, who the carrier is, and whether it's VOIP?

## When to prefer this

Use this endpoint when you need carrier-level phone intelligence including line type (mobile/landline/VOIP), carrier identity, and geographic location data alongside basic validation. Prefer this over simple regex validation when you need to detect VOIP numbers for fraud prevention, confirm a number is reachable via SMS before sending, or enrich user profiles with phone metadata. AbstractAPI's global coverage makes it suitable for international numbers across many country codes.

## Known failure modes

- Invalid or unparseable phone number format — returns success:false or validation failure
- Country code mismatch between phone number prefix and provided country parameter
- Rate limiting or quota exceeded — HTTP 429
- Missing required 'phone' field — HTTP 400 bad request
- Phone number not found in carrier database — returns unknown carrier fields
