## 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-number-parser-validator-24k-labs-df96b61c -d '<json body>'
```

Example prompt: Can you parse and validate this phone number +14155552671 — tell me its E.164 format, country calling code, and whether it's a valid length?

## When to prefer this

Choose this endpoint when you need to parse, normalize, and validate a single phone number to E.164 format with country detection at low cost ($0.002 per call). Ideal for real-time form validation, CRM data enrichment, or pre-flight checks before sending SMS. Prefer this over a full-featured identity verification service when only number format and region detection are needed.

## Known failure modes

- Number missing leading + or country code — returns parse error or invalid format
- Number too short or too long for the detected country — fails length validation
- Unrecognized or unsupported country calling code — returns unknown region
- Completely non-numeric input — returns parse error
- Missing request body or phone field — returns 400 bad request

## How this service works

Parse a phone number to E.164, detect its country calling code and region, and validate length against the E.164 standard. Provide a number with a leading + and country code.

## Output

Returns the phone number in E.164 format, the detected country calling code (e.g. +1, +44), the geographic region or country name, and a boolean or status indicating whether the number's length is valid per the E.164 standard.
