## 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 whatchuneed-phone-number-validation-3548f122 -d '<json body>'
```

Example prompt: Can you check if +14155552671 is a valid phone number and tell me what country and carrier it belongs to?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call phone number validation without committing to a subscription API like Twilio Lookup or Numverify. Ideal for agents that only occasionally need to validate phone numbers, want to avoid managing API keys for a dedicated telecom service, or are already operating within the x402 payment ecosystem.

## Known failure modes

- Invalid or unparseable phone number string returns an error status
- Missing 'input' field in request body causes a 400-level error
- Ambiguous local numbers without country code may fail to parse
- Rate limiting or payment failures via x402 protocol may reject the call
- Very obscure regional numbers may return incomplete carrier data

## How this service works

320+ pay-per-call API endpoints across accommodation, LLM, code execution, crypto, medical, finance, and more. One API, one payment. Powered by x402 protocol.

## Output

Returns a result object containing the validation status of the phone number, its parsed/normalized form (e.g. E.164 format), country code, region, carrier, and line type (mobile, landline, VoIP, etc.), along with an overall status field indicating success or failure.
