## 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 delx-commerce-phone-number-e-164-normalizer-9be2dc40 -d '<json body>'
```

Example prompt: Can you normalize '(415) 555-0100' into E.164 international format, assuming it's a US number?

## When to prefer this

Choose this endpoint when you need a cheap, no-signup, pay-per-call phone normalization service that settles instantly in USDC via x402 — ideal for AI agents that process user-submitted phone numbers in varying formats and need reliable E.164 output before passing to SMS, voice, or CRM systems. Prefer this over building your own libphonenumber integration when you want zero infrastructure overhead.

## Known failure modes

- Ambiguous phone number with no default_region provided may fail to parse or produce incorrect country code
- Invalid or nonsensical input string returns an error or empty candidate
- Unsupported or unknown region code defaults may cause misformatting
- Very short or partial number strings may not be resolvable to a valid E.164 number

## How this service works
